Un Mondiale a suo modo storico


Un Mondiale di scacchi come non si era mai visto, quello di Londra tra Magnus Carlsen e Fabiano Caruana. Da quando, nel match della riunificazione del titolo, vinto dal primo, tra il russo Vladimir Kramnik e il bulgaro Veselin Topalov, cambiò il regolamento di un match iridato dando vita a quello attuale, non era mai successo che, quando sono stati necessari, i quattro spareggi a tempo rapido si concludessero anzitempo senza bisogno di disputare il quarto perché uno solo dei due giocatori aveva vinto i primi tre, come invece ha fatto Carlsen quest’anno confermandosi sul trono per la terza volta dopo esservisi issato nel 2013. Ma soprattutto, non era mai successo che tutte e dodici le partite a tempo lungo si concludessero in parità. E sta proprio qui il punto del contendere. Dopo aver mancato la vittoria nella partita più bella, la prima, durata 115 mosse, Magnus è andato in tilt e da quel momento non ha più giocato al suo meglio, invece Caruana ha giocato quasi sempre in modo più preciso del suo avversario rischiando a sua volta di vincere la sesta partita. Magari le rivaluterò tutte in futuro, da semplice appassionato di scacchi che armeggia coi motori destinati al gioco essendo assolutamente incapace di giocare una partita a tavolino pur conoscendo bene le regole, ma quattro partite belle su dodici, e cioè la prima, la quinta, molto combattuta, la sesta e la dodicesima nella quale Carlsen ha buttato una posizione superiore proponendo la patta al suo avversario, sono troppo poche. Anche il match del 1984-1985, il primo tra Garry Kasparov e Anatoly Karpov, indubbiamente il più noioso dei cinque giocati dai due K, fu più combattuto di questo, dato che delle 40 patte su 48 partite tra i due (servivano 6 vittorie a uno dei due giocatori per vincere il match senza contare le patte) ci furono tante sfide combattute in cui i contendenti per errori reciproci mancarono qualche vittoria a testa. Dopo quel match la federscacchi internazionale ripristinò saggiamente il regolamento precedente al 1978 prevedendo 24 partite e se il match finiva pari il campione in carica manteneva il titolo. Sarebbe il caso di ripristinarlo anche adesso ed eliminare le partite di spareggio: i motori scacchistici hanno fatto diventare i migliori giocatori del mondo (e Carlsen e Caruana sono i primi due delle classifiche) quasi delle macchine, e il rischio che le 12 partite dell’attuale regolamento finiscano tutte patte c’è eccome, a maggior ragione se il match lo giocano due come Magnus e Fabiano. Sulla distanza di 24 partite a tempo lungo c’è invece la possibilità che uno o tutti e due i giocatori si stanchino e crollino (come successo a Caruana nelle partite rapide dove peraltro si è rivisto il vero Carlsen). Voi direte: ma c’è il rischio che anche le 24 partite finiscano tutte patte. Ma con la clausola che se il match finisce pari il titolo rimane al campione, lo sfidante, man mano che le partite passano, deve provare a fare qualcosa di più perché non avrebbe l’eventuale ancora di salvezza degli spareggi, e poi voglio vedere se uno dei due non commette degli errori decisivi! Insomma, un match, quello londinese, a suo modo storico per i motivi che abbiamo detto all’inizio, ma che deve far riflettere seriamente la federscacchi sull’attuale regolamento e sull’eventualità di cambiarlo. Così come va cambiato quello del Mondiale femminile, nel quale la campionessa del mondo cinese Jun Wenjun, a sei mesi dall’aver conquistato il titolo, ha dovuto rimetterlo in palio (ma per fortuna lo ha confermato) in un torneo a tabellone tennistico a 64 giocatrici.

Magnus Carlsen campione del mondo di scacchi per la quarta volta

Dopo dodici patte in tutte e dodici le partite a tempo lungo della sfida, nell’ultima delle quali il campione in carica, in una posizione superiore, alla 31a mossa ha incredibilmente proposto la divisione del punto allo sfidante che l’ha immediatamente accettata, negli spareggi a tempo rapido il match mondiale di scacchi di Londra è andato a finire com’era prevedibile, e cioè con la conferma del titolo iridato da parte del norvegese Magnus Carlsen che aveva già trionfato con l’indiano Viswanathan Anand nel 2013 e nel 2014 rispettivamente in dieci e undici partite a tempo lungo, due e una d’anticipo, e che nel 2016 aveva avuto la meglio sul russo di origine ucraina Sergey Karjakin, che dopo aver resistito e pattato le prime due partite a tempo rapido si dovette arrendere nelle ultime due. Oggi Carlsen ha letteralmente surclassato Fabiano Caruana vincendo tre partite su tre ciascuna con 25 minuti a disposizione sull’orologio con l’incremento di 10 secondi a mossa per giocatore e pertanto non c’è stato bisogno della disputa dell’ultima. Dopo le precedenti partite in cui entrambi avevano brillato più col Nero che col Bianco, ma Carlsen, che tuttavia nelle ultime fasi del match era letteralmente terrorizzato di perdere, era stato particolarmente passivo, oggi si è finalmente rivisto il vero Magnus, quello che tutti ammirano in ogni cadenza di gioco, ma è chiaro che in quella delle partite di oggi sarebbe partito avvantaggiato contro chiunque al mondo, e ancor più nelle partite lampo se si fossero disputate. Fabiano ha invece profuso una quantità enorme di energie nei giorni scorsi per tenere testa al suo avversario e purtroppo oggi è crollato: nella prima partita, un’inglese simil siciliana a colori invertiti, dopo un inizio a fasi alterne, ha cominciato a sbagliare poco prima della quarantesima mossa e la sua posizione si è letteralmente sbriciolata, Fabiano ha inutilmente provato a resistere e a provare a mandare fuori tempo massimo il suo avversario ma ha dovuto alzare bandiera bianca alla 55a mossa, in un finale di torre e con due pedoni in più da parte di Carlsen che giocava col Bianco. Nella seconda partita, una siciliana variante Sveshnikov, Caruana, dopo essere stato anche in vantaggio posizionale coi pezzi bianchi, nel centropartita ha commesso un errore alla 26a mossa e uno ancora più grave alla 28a, forse il più grave del match, quando ha portato un cavallo nella casella d5 invece della regina, per poi abbandonare subito dopo la risposta dell’avversario. Infine, nella terza partita, un’altra siciliana ma con variante Paulsen-Taimanov, Carlsen col Bianco ha giocato con l’evidente intenzione di pattare e assicurarsi il mezzo punto decisivo per conservare il titolo, ma Fabiano ha nuovamente sbarellato e nel giro di meno di dieci mosse la sua posizione è andata in pezzi con Magnus che ha potuto anche promuovere un suo pedone guadagnandosi una seconda regina e il match è finito alla 51a mossa. Di seguito lo svolgimento delle ultime tre partite a tempo lungo e delle tre a tempo rapido, per le quali domani metteremo i commenti in inglese degli esperti di ChessBase, già presenti invece per la 10a, 11a e 12a partita.

There were plenty of games where one side did not make the most of their chances, but this has been the only one where I thought both players at some point had very real winning chances.} 1. e4 c5 2. Nf3 Nc6 {Magnus stays true to his Rossolimo/Sveshnikov repertoire for the 5th time in a row. Starting from game 5, I have expected him to pivot every single game, and been wrong every single time. Perhaps he will just play this the whole way through?} 3. d4 {Caruana eschews Bb5, which he chose in his first 3 White games.} cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Nd5 {I was a bit surprised to see Caruana enter the same line as game 8. Even though he got an excellent position in that game, he had to figure Magnus would have come with improvements, and the line is supposed to be okay for Black.} (7. Bg5 {Leads to the mainline Sveshnikov.} )Nxd5 8. exd5 Nb8 9. a4 Be7 10. Be2 0-0 11. 0-0 Nd7 12. b4 $5 {The first major deviation. Caruana chose Bd2 in the previous game. Still, the move does not look too impressive to me.} (12. Bd2 { Carlsen misplayed the position and quickly ended up worse.} )a6 13. Na3 a5 $5 {A very commital decision, but not a bad one. Magnus forces the queenside open right away, a fearless decision against a prepared opponent, but he had other options.} (13... b6 {Appeals the most to me. Black tries to keep the queenside closed and will look for his own counterplay with f7-f5. In fact, I actually prefer Black in a practical game here.} )14. bxa5 Rxa5 15. Nc4 Ra8 16. Be3 {Caruana was still playing very fast. He probably was in his preparation.} f5 $1 {Black absolutely needs counterplay, and f5-f4 is coming. However, unlike game 8, here White cannot comfortabll play f2-f4 himself to keep his kingside secure.} 17. a5 (17. f4 {Black is absolutely fine after} exf4 18. Bxf4 Nb6 (18... g5 $5 {If Black is in a feisty mood} ))f4 $1 18. Bb6 Qe8 {The battle lines are drawn. White clearly has an edge on the queenside, Black's pieces (particularly the c8-bishop and d7-knight) look a little clumsy, and the b6 square could prove to be a problem. But Black's kingside pawn mass promises him decent counterplay.} 19. Ra3 {A not so mysterious rook move. It looks pointless now but Black's plan is clearly to launch a kingside attack, and the rook will be a good defender laterally along the third rank.} (19. Re1 {This is the computer's recommendation by a wide margin, but I don't really understand the move? I guess it just serves as some vague prophylaxis against e5-e4. It claims white is better but I am unconvinced because after} Rf6 $1 { Black is ready to challenge the b6-bishop via Be7-d8.} )Qg6 20. Bc7 e4 $1 {Carlsen is in burn the bridges mode. His pawns are vulnerable and could quickly fall if the center were to open at an inopportune moment, but he is looking for direct counterplay against White's king, truly in the style of the Sveshnikov.} (20... Ra6 {A quiet defensive move like this one was surely fine, but I think the World Champion was right to go for it.} )(20... b5 $5 {It was also possible to play in the same manner as the game, only without committing to e5-e4. This could make some sense as the central pawns proved weak.} 21. Nb6 (21. axb6 $2 {It's possible this move annoyed Magnus since e5-e4 no longer works, but it is also insufficient.} Rxa3 22. Nxa3 {The problem is here Black needs a new attacking plan since e5-e4 fails to bring its desired returns.} Nc5 $1 {The b-pawn is well under control, and most importantly, White's pieces are totally unprepared to defend his king. How will the c7-bishop ever contribute to a proper defense? Rf6-h6 is coming and Black should win.} (22... e4 23. Bh5 $1 Qg5 24. Qg4 $1 {White is doing well. Getting his queen to g4 will really lesse any attacking chances Black can hope for} ))Nxb6 22. Bxb6 {This leads to a similar position to the game, but Black does not need to play e5-e4 if he so desires. For instance, he seems to have a good position after} b4 23. Rb3 Bf5 $1 {When it is clear there are reasons the pawn is good on e5 as well.} )21. Kh1 b5 $5 {A very commital move, but not a bad one.} (21... Qh6 {The machines prefer a slower buildup with something like this. Black certainly will have attacking chances by lifting the f8-rook, but I don't mind Magnus's decision either.} )22. Nb6 $1 (22. axb6 $2 {This would be asking for trouble. I find it unlikely White will survive after the energetic} Rxa3 23. Nxa3 f3 $1 24. gxf3 Ne5 $1 {Black's attack looks devastating.} )Nxb6 23. Bxb6 Qg5 $6 {Technically, this move loses the game against best play, but it comes with a very nasty idea of playing Rf6-h6 and delivering mate on the h-file. A machine with its nerves of steel would have no trouble grabbing h5, but for a human, it looks absurdly dangerous.} 24. g3 {Caruana's move makes a lot of sense. Taking on f4 and bringing the rook to g3 should dispel any mating dreams.} (24. Bxb5 $1 {White could have gotten away with this.} Rf6 {Extreme precision is needed to beat back the attack, but it is possible.} 25. Re1 $1 {An important move. White hits the e4-pawn while simultaneously clearing f1 for the bishop.} Bf5 (25... Rh6 26. Rxe4 )(25... Rg6 26. Bf1 Bf5 (26... Ba6 27. Rxe4 $1 $18 )27. a6 Rh6 28. a7 Qh4 29. h3 f3 {This loks absolutely terrifying for a human, but apparently White wins with another only move:} 30. Qd4 $1 $18 {The point is to defend against the threat of Bxh3 followed by Qg4.} Bxh3 31. gxh3 Qg4 32. Rxf3 $1 {No more exf3 thanks to the pin exerted by the queen being on d4. After} Qxf3+ 33. Bg2 {The a-pawn will carry the day. One certainly cannot fault Caruana for not seeing all of this.} )26. f3 $1 e3 27. a6 Rh6 28. Re2 $3 { An incredibly difficult only move that would have to have been prepared in advance. White is ready to play Qg1 and hold the position together. Even then, the variation continues.} Qh5 29. Qg1 Bh4 30. g4 $1 fxg3 31. Raxe3 $1 {White wins. But this is really just a machine line, and outside of human capability.} )b4 25. Rb3 (25. gxf4 {I would have been tempted to clear the 3rd rank for defensive purposes, and this probably is an easier route to equality. Still, while Caruana's choice gives him some only moves to find, he did find the moves and he objectively was not worse.} )Bh3 26. Rg1 $1 {The rook is needed for defensive purposes.} (26. Re1 Bf6 $1 {Moves like Bc3 or Be5 could come next. White is in trouble.} )f3 {White is under a lot of pressure. Around here I thought Caruana might crack and give Magnus the first decisive result, but he defended very well.} 27. Bf1 $1 {This is a tough move. I would have been tempted to just let the bishop stay on h3, since White can always sacrifice an exchange on g2 very happily and otherwise it's not clear what active role the bishop plays. But it was absolutely critical to play Bf1.} (27. Bb5 $2 {A move like this looks sensible...} Rf6 $1 {Until you realize White will simply be mated on the h-file! Rh6 and Qh5 is coming, and there is nothing to be done.} )Bxf1 $1 (27... Qh5 {Caveman play does not work here since White is in better shape to keep the h-file under control. The queen coming to f1 is very important, for instance after} 28. Rxb4 Rf6 29. Bxh3 Qxh3 30. Be3 $1 {Black will not get Rh6 very easily, and e4 is hanging to boot. White should win.} )28. Qxf1 $1 {Another important decision. White cannot allow a disaster on the h-file. His position looks awful with the queen and the rook so passively placed and the d5-pawn falling, but he remains solid and can rely on the a5-pawn for counterplay.} (28. Rxf1 $2 {Keeping active pieces comes at a heavy price. After} Qg4 $1 29. Rxb4 Rf5 $1 {White will promptly be mated by Rh5 and Qh3.} )Qxd5 29. Rxb4 Qe6 30. Rb5 $11 {The position is dynamically balanced, but White has to be more careful than Black. He managed without a ton of trouble.} Bd8 31. Qe1 $1 {The queen returns to life.} Bxb6 32. axb6 Rab8 33. Qe3 Qc4 34. Rb2 Rb7 35. Rd1 Qe2 $1 {Setting a devilish trap, though it is not enough to claim an advantage.} 36. Re1 $1 {Far from the only holding move, but I am awarding an exclamation point for not falling for Black's idea.} (36. Qb3+ $2 Kh8 37. c4 {Looks like it traps Black's queen. But the nasty response} Rxb6 $1 $19 {Would promptly turn the tables!} )Qxe3 37. Rxe3 d5 {The position is balanced as neither side can easily mobilize their pawn majority. Black's center looks impressive, but he can't do anything with it so long as he is left with a passive rook on b7.} 38. h4 Rc8 39. Ra3 Kf7 40. Kh2 Ke6 41. g4 Rc6 42. Ra6 Ke5 43. Kg3 h6 44. h5 {The position is some kind of mutual stalemate where neither side can do anything. Magnus tried to make something happen with} Kd4 $2 {But only made trouble for himself after the strong response} 45. Rb5 $1 {When Black has to be somewhat accurate to not get into trouble. Still, he has more than one route to a draw, and Magnus found a very easy one.} Rd6 $1 {Overprotecting the d5-pawn White was planning to harass with Raa5.} 46. Ra4+ Ke5 47. Rab4 Ke6 {Nice and easy. White has no good way to challenge Black's central pawn mass without allowing liquidation.} 48. c4 dxc4 49. Rxc4 Rdxb6 50. Rxe4+ Kf7 51. Rf5+ Rf6 {Black loses a pawn but simplifies into an easily drawn 3 vs 2 on the kingside. Caruana did not even bother trying. His winning chances are approximately zero.} 52. Rxf6+ Kxf6 53. Kxf3 Kf7 54. Kg3 {With only 2 games to go, each player has only one game to try with White.

In order to be able to play such a sharp opening you have to come very well prepared; there are many pitfalls and traps that Black can easily fall into in the Sveshnikov.

Magnus must be really looking forward to the rapid tiebreaks, as he did two years ago against Sergey Karjakin. He missed great winning opportunities on move 25 and move 29 and I sort of suspect he came into the game with an eye on the tiebreaks. It's also posisble that he just wanted to make a lot of people happy (including myself). As two years ago we again get to see a four game rapid playoff! I am very excited to watch this match live.

Fake newspapers


Oggi non parlerò principalmente di scacchi poiché la decima partita del Mondiale di Londra tra Magnus Carlsen e Fabiano Caruana è stata un'altra noiosissima patta, la decima, malgrado la taglientissima variante Sveshnikov scelta per la seconda volta in questo match dal campione in carica che giocava col Nero. In ogni modo, se qualcuno si strappasse i capelli e volesse dare un'occhiata a questa partita la trova alla fine di questo post. Anzi, di scacchi oggi parlerò ancora perché si è concluso il Mondiale femminile, peraltro molto più combattuto di quello maschile malgrado la formula demenziale, con la conferma del titolo da parte della campionessa del mondo, la cinese Ju Wenjun. Volevo invece parlare, spero brevemente, della disinformazione che ormai da almeno un quarto di secolo c'è in Italia per quanto riguarda la politica, nel senso che tutti coloro che cercano di cambiare le cose in questo schifoso paese vengono puntualmente massacrati dai grandi media, che alla fine vincono regolarmente le loro battaglie. Ci hanno provato e ci stanno ancora provando coi 5 Stelle e coi loro governi, locali o nazionali. Ma questo modo di disinformare si sta purtroppo estendendo anche allo sport. Basandosi sulle "stories" pubblicate su Instagram sul suo profilo da parte della diretta interessata, sembrerebbe secondo alcuni media (Gazzetta, Ansa e Repubblica, quest'ultima fondata dal più parziale e più comunista dei giornalisti italiani, quello che voleva l'impeachment per Francesco Cossiga e non per Giorgio Napolitano, che ne ha combinate ben di peggio), sembrerebbe che Elena Fanchini annunci il ritiro. Ma la 33enne bresciana di Montecampione, che è appena guarita dal tumore che l'aveva colpita e che è caduta rovinosamente in allenamento pochi giorni fa, non menziona neanche lontanamente la parola RITIRO! Vi prego, non leggete più questi grandi giornali e non guardate più i loro siti internet! Leggete invece di più i blog come questo di questo povero sfigato, che magari esce più tardi degli altri con le notizie per i siti per i quali lavora ma almeno cerca di verificarle!

Ah dimenticavo, ecco qui sotto la decima partita del Mondiale di scacchi coi commenti per ChessBase del Grande Maestro campione in carica degli Stati Uniti Sam Shankland. Foto: Instagram Elena Fanchini.

There were plenty of games where one side did not make the most of their chances, but this has been the only one where I thought both players at some point had very real winning chances.} 1. e4 c5 2. Nf3 Nc6 {Magnus stays true to his Rossolimo/Sveshnikov repertoire for the 5th time in a row. Starting from game 5, I have expected him to pivot every single game, and been wrong every single time. Perhaps he will just play this the whole way through?} 3. d4 {Caruana eschews Bb5, which he chose in his first 3 White games.} cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7.

Still, the move does not look too impressive to me.} (12. Bd2 { Carlsen misplayed the position and quickly ended up worse.} )a6 13. Na3 a5 $5 {A very commital decision, but not a bad one. Magnus forces the queenside open right away, a fearless decision against a prepared opponent, but he had other options.} (13... b6 {Appeals the most to me. Black tries to keep the queenside closed and will look for his own counterplay with f7-f5. In fact, I actually prefer Black in a practical game here.} )14. bxa5 Rxa5 15. Nc4 Ra8 16. Be3 {Caruana was still playing very fast. He probably was in his preparation.} f5 $1 {Black absolutely needs counterplay, and f5-f4 is coming.

Bxf4 Nb6 (18... g5 $5 {If Black is in a feisty mood} ))f4 $1 18. Bb6 Qe8 {The battle lines are drawn. White clearly has an edge on the queenside, Black's pieces (particularly the c8-bishop and d7-knight) look a little clumsy, and the b6 square could prove to be a problem. But Black's kingside pawn mass promises him decent counterplay.} 19. Ra3 {A not so mysterious rook move. It looks pointless now but Black's plan is clearly to launch a kingside attack, and the rook will be a good defender laterally along the third rank.} (19. Re1 {This is the computer's recommendation by a wide margin, but I don't really understand the move? I guess it just serves as some vague prophylaxis against e5-e4. It claims white is better but I am unconvinced because after} Rf6 $1 { Black is ready to challenge the b6-bishop via Be7-d8.} )Qg6 20. Bc7 e4 $1 {Carlsen is in burn the bridges mode. His pawns are vulnerable and could quickly fall if the center were to open at an inopportune moment, but he is looking for direct counterplay against White's king, truly in the style of the Sveshnikov.} (20... Ra6 {A quiet defensive move like this one was surely fine, but I think the World Champion was right to go for it.} )(20... b5 $5 {It was also possible to play in the same manner as the game, only without committing to e5-e4. This could make some sense as the central pawns proved weak.} 21. Nb6 (21. axb6 $2 {It's possible this move annoyed Magnus since e5-e4 no longer works, but it is also insufficient.} Rxa3 22. Nxa3 {The problem is here Black needs a new attacking plan since e5-e4 fails to bring its desired returns.} Nc5 $1 {The b-pawn is well under control, and most importantly, White's pieces are totally unprepared to defend his king. How will the c7-bishop ever contribute to a proper defense? Rf6-h6 is coming and Black should win.} (22... e4 23. Bh5 $1 Qg5 24. Qg4 $1 {White is doing well. Getting his queen to g4 will really lesse any attacking chances Black can hope for} ))Nxb6 22.

Qh6 {The machines prefer a slower buildup with something like this. Black certainly will have attacking chances by lifting the f8-rook, but I don't mind Magnus's decision either.} )22. Nb6 $1 (22. axb6 $2 {This would be asking for trouble. I find it unlikely White will survive after the energetic} Rxa3 23. Nxa3 f3 $1 24. gxf3 Ne5 $1 {Black's attack looks devastating.} )Nxb6 23. Bxb6 Qg5 $6 {Technically, this move loses the game against best play, but it comes with a very nasty idea of playing Rf6-h6 and delivering mate on the h-file. A machine with its nerves of steel would have no trouble grabbing h5, but for a human, it looks absurdly dangerous.} 24. g3 {Caruana's move makes a lot of sense. Taking on f4 and bringing the rook to g3 should dispel any mating dreams.} (24. Bxb5 $1 {White could have gotten away with this.} Rf6 {Extreme precision is needed to beat back the attack, but it is possible.} 25. Re1 $1 {An important move. White hits the e4-pawn while simultaneously clearing f1 for the bishop.} Bf5 (25... Rh6 26. Rxe4 )(25... Rg6 26. Bf1 Bf5 (26... Ba6 27.

Rb3 (25. gxf4 {I would have been tempted to clear the 3rd rank for defensive purposes, and this probably is an easier route to equality. Still, while Caruana's choice gives him some only moves to find, he did find the moves and he objectively was not worse.} )Bh3 26. Rg1 $1 {The rook is needed for defensive purposes.} (26. Re1 Bf6 $1 {Moves like Bc3 or Be5 could come next. White is in trouble.} )f3 {White is under a lot of pressure. Around here I thought Caruana might crack and give Magnus the first decisive result, but he defended very well.} 27. Bf1 $1 {This is a tough move. I would have been tempted to just let the bishop stay on h3, since White can always sacrifice an exchange on g2 very happily and otherwise it's not clear what active role the bishop plays. But it was absolutely critical to play Bf1.} (27. Bb5 $2 {A move like this looks sensible...} Rf6 $1 {Until you realize White will simply be mated on the h-file! Rh6 and Qh5 is coming, and there is nothing to be done.} )Bxf1 $1 (27... Qh5 {Caveman play does not work here since White is in better shape to keep the h-file under control. The queen coming to f1 is very important, for instance after} 28. Rxb4 Rf6 29. Bxh3 Qxh3 30. Be3 $1 {Black will not get Rh6 very easily, and e4 is hanging to boot. White should win.} )28. Qxf1 $1 {Another important decision. White cannot allow a disaster on the h-file. His position looks awful with the queen and the rook so passively placed and the d5-pawn falling, but he remains solid and can rely on the a5-pawn for counterplay.} (28.

But the nasty response} Rxb6 $1 $19 {Would promptly turn the tables!} )Qxe3 37. Rxe3 d5 {The position is balanced as neither side can easily mobilize their pawn majority.

Kg3 h6 44. h5 {The position is some kind of mutual stalemate where neither side can do anything. Magnus tried to make something happen with} Kd4 $2 {But only made trouble for himself after the strong response} 45. Rb5 $1 {When Black has to be somewhat accurate to not get into trouble. Still, he has more than one route to a draw, and Magnus found a very easy one.} Rd6 $1 {Overprotecting the d5-pawn White was planning to harass with Raa5.} 46. Ra4+ Ke5 47. Rab4 Ke6 {Nice and easy. White has no good way to challenge Black's central pawn mass without allowing liquidation.} 48. c4 dxc4 49. Rxc4 Rdxb6 50. Rxe4+ Kf7 51. Rf5+ Rf6 {Black loses a pawn but simplifies into an easily drawn 3 vs 2 on the kingside. Caruana did not even bother trying. His winning chances are approximately zero.} 52. Rxf6+ Kxf6 53. Kxf3 Kf7 54. Kg3 {With only 2 games to go, each player has only one game to try with White. Carlsen gets to go first, and I'll be interested to see what first move he chooses, as well as if we will see a 6th 2.Nf3 Nc6 Sicilian in the final game.} 1/2-1/2

Mondiale di scacchi: stabilito il record (poco invidiabile) di nove patte su nove partite

A Londra, nel mondiale di scacchi tra Magnus Carlsen e Fabiano Caruana, è stato stabilito un record, ma non di vittorie consecutive, bensì di patte consecutive iniziali: nove. Chi ha letto i miei precedenti post sa di chi era il record precedente e quindi non lo ripeto. I due protagonisti hanno ripetuto l’apertura della quarta partita, guarda caso la più noiosa, e cioè la variante dei quattro cavalli col fianchetto sul lato di re di una partita inglese che in realtà è una siciliana a colori invertiti. Carlsen alla nona mossa è stato il primo a deviare il gioco rispetto alla suddetta quarta partita, ma questa, pur essendo durata 56 mosse invece di 34, è stata altrettanto noiosa. La patta, fatta eccezione per un temporaneo vantaggio posizionale per il campione in carica, non è mai stata in discussione, la partita è finita con re, alfiere delle caselle chiare e due pedoni per il Bianco (Carlsen) contro re, alfiere delle caselle scure e due pedoni per il Nero (Caruana), il cosiddetto finale di alfieri dalle caselle di colore contrario che quindi non si incontreranno mai. L’unico brivido di queste ultime ore è un occhio ferito di Carlsen, come si vede dalla foto da lui (e da me) pubblicata su Instagram, che si è procurato giocando a calcio. Francamente, per me che non capisco nulla di scacchi e che mi aiuto coi motori scacchistici visto che so solo muovere i pezzi, comincia a essere molto difficile commentare questa sfida iridata. Di partite realmente appassionanti ce ne sono state due, e altre due solo per metà, per il resto Magnus e Fabiano hanno giocato come due motori scacchistici contrapposti e francamente vedo durissima come nelle restanti tre partite a tempo lungo ci possa essere una vittoria di uno dei due, anche perché regnerà sovrana in entrambi la paura di perdere. Di più, questi sarebbero capaci di pattare anche tutte le eventuali partite a gioco rapido in calendario il 28 novembre, anche se Carlsen è nettamente favorito in quel format e lo sarebbe contro chiunque. Di seguito lo svolgimento della nona partita con, per fortuna, i commenti per ChessBase di chi ne capisce di scacchi molto ma molto di più di me, e cioè del Grande Maestro ceco David Navara, numero 39 del mondo. Oggi la decima partita.

After eight rounds, there remained four games and an eventual tie-break to be played to determine the winner. The finale of the Women’s World Championship looks quite similar in this respect, doesn’t it? The match has been quite tense, both players have been fighting hard and it is therefore surprising that all the games finished in draws. This shows high class of both players as well as their superb defensive abilities. Moreover, the permanent progress of the opening theory makes it increasingly difficult to achieve an advantage with White against a well-prepared opponent. We all have probably hoped to see more decisive games, but it is really very hard to beat a 2800-rated player.} 1. c4 e5 2. Nc3 Nf6 3. Nf3 Nc6 4. g3 d5 5. cxd5 Nxd5 6.

This seemingly unambitious variation with few long forced lines gives him decent chances to outplay his opponent in the subsequent course of the game.

Bc6 {, as} Bxe3 $2 {loses an exchange after almost any queen retreat.} )22. Bxb7 Rad8 23. Rad1 $14 {White has achieved a small but stable advantage. His king is safer and his bishop is more active than its counterpart. He should keep the queens on the board to maintain attacking chances. Magnus Carlsen has already won many equal-looking positions with rooks and opposite-coloured bishops on the board. On the other hand, Black's position is quite solid and the drawing margin is quite broad unless White launches a mating attack.

Kg2 Kf6 43. f4 Bb6 44. Kf3 h6 {Black does not advance his pawns to far to be able to protect them. Watching this endgame, I recalled an important game Aronian - Bacrot from the World Cup 2005 semifinal, where Black gave up in a similar position without his c-pawn and with White's bishop on h3 and pawn on f5. It looks like a dream scenario for White, but the final position of that game was still drawn! Needless to say, White cannot achieve it now.} 45. Ke4 Ba7 46. Bg4 {From here White's bishop blocks the h-pawn and protects the f4-pawn. White can win a bishop for the a-pawn, but then Black's c-pawn could run forward to save a draw (at least).} Bg1 47.

Mondiale di scacchi: ottava patta su otto partite e molto rumore per nulla



Poteva essere una partita in cui uno dei due protagonisti avrebbe finalmente potuto incassare un punto intero e non soltanto mezzo e invece l’ottavo atto della sfida mondiale di Londra tra Magnus Carlsen e Fabiano Caruana è finita ancora una volta patta. E’ stato così eguagliato il record di patte iniziali in un match iridato, quello finora detenuto da Garry Kasparov e Viswanathan Anand, che pareggiarono le prime otto partite del Mondiale PCA, la Professional Chess Association creata da Kasparov per gravi contrasti con la FIDE, la federscacchi internazionale, Kasparov perse la nona ma poi sconfisse il grande campione indiano in quattro delle successive cinque conservando il titolo. Eppure le premesse perché uno dei due potesse vincere c’erano tutte: lo sfidante italostatunitense coi pezzi bianchi deve affrontare ancora una volta la difesa siciliana ma finalmente alla terza mossa si decide a giocare la variante aperta che prevede uno scambio di pedoni in d4, il campione in carica norvegese da parte sua alla quinta mossa gioca la variante Sveshnikov, una delle più taglienti di tutta la teoria delle aperture nonché una delle più popolari. Il duello è molto interessante, tanto più che Carlsen, che stavolta dimostra finalmente di voler giocare per vincere, finisce in posizione inferiore per un attacco di pedoni troppo impulsivo sul lato di re, ma Caruana alla 24a mossa invece di attaccare l’alfiere avversario delle caselle scure in d6 portando il cavallo in c4 oppure, meglio ancora, di entrare nel campo avversario con la regina in h5, avanza di una casella il pedone h mancando la concretizzazione di un vantaggio che, seppur non decisivo, era pur sempre un vantaggio. Da lì in poi la partita non ha molta storia e dopo 38 mosse i due si accordano per l’ennesima patta quando Fabiano ha re, una torre, alfiere delle caselle scure e quattro pedoni e Magnus re, una torre, alfiere delle caselle chiare e quattro pedoni. Ricordiamo che il record di patte consecutive (non iniziali) in una sfida mondiale è di diciassette (17!) nell'epico match tra Kasparov e Anatoly Karpov che si protrasse a cavallo tra il 1984 e il 1985 prima di essere sospeso dalla FIDE dopo 48 partite, in quello stesso duello i due inanellarono un'altra serie di 14 patte consecutive: entrambe queste serie non saranno più ripetibili, almeno per le partite a tempo lungo, visto che l'attuale regolamento, a mio avviso molto discutibile, ne prevede solo 12. Oggi quarto giorno di riposo prima della nona partita di domani. Di seguito lo svolgimento della partita di ieri coi commenti per ChessBase del Grande Maestro statunitense di origini filippine Wesley So, numero 10 delle classifiche mondiali e grande avversario di entrambi.

[Event "World Chess Championship 2018"] [White "Caruana, Fabiano"] [Black "Carlsen, Magnus"] [Site "London"] [Round "8"] [Annotator "So, Wesley"] [Result "1/2-1/2"] [Date "2018.11.19"] [ECO "B33"] [WhiteElo "2832"] [BlackElo "2835"] [PlyCount "75"] {Game 8 of the Carlsen-Caruana match. Many questions are in the air. Are we going to see the same Sicilian Rossolimo or will we finally see 1.e4 e5? Will they break the drawing streak and someone draw first blood?} 1. e4 {Fabiano sticks to his openings as you can see from his games so far. With White he plays 1.e4 and with Black he does not change his lines. This is not really surprising as this flow is recommended in many top matches. Plus, Leinier Dominguez being one of his assistants and a fan of this same system himself, I think it's safe to assume we will see 1.e4 whenever Fabiano is White here in London.} c5 {I can't help wondering though why Magnus sticks to the Sicilian in these games. Against Sergey Karjakin two years ago he only played 1...e5 and had absolutely no problems. I suppose it's a matter of fashion and personal preference. Before this Championship match the Sicilian was never really the main opening of Magnus even less so the Sveshnikov.} 2. Nf3 Nc6 3. d4 {Checking what Magnus had prepared against the Open Sicilian, I must say I am surprised that Fabiano avoided going for 3.Bb5. He must have run out of good ideas there.} cxd4 4. Nxd4 Nf6 5. Nc3 e5 {Now we see the long-awaited Sicilian Sveshnikov! This opening became very popular during the late 90s and early 2000s thanks to the effort of Kasparov, Kramnik and Leko. These days it has a rock solid reputation and is often employed as a barricade to any White attempts at an advantage. It is obvious Fabiano expected this and accordingly prepared a special idea. The Sveshnikov holds good memories for me as back in the days of my youth it was my one and only opening against 1.e4. One of my first ever chess books was by Mikhail Krasenkow published in 1996! I also had books by Yuri Yakovich and Dorian Rogozenco on this specific opening. It is always a pleasure for me to annotate a game on an opening that has good vibes for me.} 6. Ndb5 d6 7. Nd5 Nxd5 8. exd5 Nb8 {This is the main retreat, the knight will be transferred to the kingside via d7 later on. Even though I have not checked the most updated theory here recently, it is known that this is the most solid option for Black.} ({Retreating to e7 is possible} 8... Ne7 { where Black's plan next consists of Nf5 followed by ...g6-Bg7.} )9. a4 { This is the first surprise. 9.c4 is the main move here. I wonder if Magnus' team preparation anticipated this. It is not clear yet if this idea poses any serious threat to the Sveshnikov. I am sure over the board it can be difficult to face.} ({The normal continuation for most games here is} 9. c4 Be7 10. Be2 0-0 11. 0-0 a6 12. Nc3 f5 {where we have a typical position. White has a grip on the queenside while Black has more space on the other flank. The position should be close to equal. I had this position in some of my games many years ago. One of them went} 13. f3 Nd7 14. Rb1 Bg5 15. b4 b6 16. a3 $14 {when White seems slightly better but the game ended in a draw later on. ½-½ (58) Wan,Y (2471)-So,W (2577) Manila 2008} )Be7 10. Be2 0-0 11. 0-0 Nd7 (11... f5 12. Bd2 f4 )12. Bd2 {Quiet, refined and dangerous moves like this one are very much Caruana! Remember 9.Bd2 in the Ruy Lopez against Aronian in the Candidates? (Though to be fair Grischuk played it first.) Anyway my point is, there is more to this move than meets the eye.} f5 {This looks like a most natural response.} (12... Nf6 {Seems like a good move that requires further research. After} 13. Be3 a6 14. Na3 Qa5 $5 {A funny instance that could work.} 15. c4 Qd8 $5 {The idea is to blockade the queenside dark-squares with a5 and b6.} 16. Nc2 (16. b4 a5 )a5 17. Na3 b6 {Black has accomplished his strategy and the position now looks very interesting to me.} )13. a5 a6 (13... f4 $5 14. Bb4 Nf6 15. c4 a6 16. Nc3 Bf5 17. f3 )14. Na3 e4 {I think Magnus is playing all the most logical moves here. He fixes the problem of needing more space for his pieces by securing the e5 post for his knight.} (14... f4 { is one of the suggestions I saw on the live book.} 15. Nc4 Rf6 {The idea is to attack on the kingside with Rh6 while keeping the b6 square protected for the moment.} )(14... Nf6 15. Bb4 Bd7 16. Nc4 Bb5 17. Nb6 Bxe2 18. Qxe2 Rb8 19. f4 $14 )15. Nc4 Ne5 16. Nb6 {Keeping the queenside in check. This protected knight is very annoying on b6 and it controls many squares. Now White can always grab the bishop pair if need be.} (16. Nxe5 dxe5 17. Bc4 Bd6 18. Re1 Bd7 19. Bf1 )Rb8 17. f4 exf3 18. Bxf3 g5 $6 {The best word to describe my thoughts when I first saw this move is "shocking"! This looks at first sight like utter desperation. With a powerful knight on b6 tying down Black's queenside and significantly more space, it looks like White's opportunities have a substantially higher chance to succeed.} ({It seems to me that much stronger is} 18... Bf6 19. c3 Nd7 {to get rid of the annoying White knight. The f6 bishop can then be posted on e5.} 20. Be3 Be5 )({Or Black can also start with} 18... Nd7 )19. c4 {While watching this game live I thought Magnus was in deep danger here. His attack does not seem to be going anywhere. At the same time Black has to be careful not to weaken his king's position. And White's play on the queenside is definitely faster. We might finally see a decisive result today!} f4 20. Bc3 ({Trading the light-squared bishops with} 20. Be4 {is a serious option too.} Bf5 21. Bxf5 Rxf5 22. Bc3 {White has a stable advantage.} )Bf5 (20... Bf6 {is met by the same c5} 21. c5 $1 { it is incredible how powerful this pawn sacrifice can be.} dxc5 22. d6 Nxf3+ 23. gxf3 Bxc3 24. bxc3 Be6 25. Re1 $18 {when White is just totally winning. The knight on b6 and the pawn on d6 totally bind up Black's forces.} )21. c5 $1 {Fabiano is playing accurately and powerfully. White wastes no time in mobilizing his forces at the cost of a pawn.} Nxf3+ (21... Bf6 22. c6 $16 )22. Qxf3 dxc5 23. Rad1 {This seems like a most natual move. What can be more instinctive than putting a rook behind a passed pawn? But here White had two great opportunities that would almost certainly lead to a win.} (23. g4 $1 { is an enormously powerful move. It kicks away Black's bishop from its ideal square on f5. After} Bg6 (23... fxg3 24. Qxg3 {leads to a winning attack. After } Bd6 {White has Be5, with irresistible threats.} )24. Rad1 Bd6 (24... Bf6 25. d6 $18 {Once the d-pawn reaches d6, it is over.} )25. Rfe1 {White is cruising to the win. Black cannot defend against the rook infiltration on e6. Nc4 is another huge threat.} c4 26. Re6 Qc7 27. Qh3 $18 )(23. Rae1 Bf6 (23... Bd6 24. Nc4 )24. h4 {also looks absolutely dominating. After} h6 25. hxg5 hxg5 { We have the now familiar motif} 26. g4 {which just crushes Black's defences. Of course although in both cases the lines are totally winning for White, lets be fair. It's easy to see it with a coffee in one hand, a sandwich in the other, and an incredibly powerful computer analyzing lines right in front of you. Poor Carlsen and Caruana have to do all the calculating in their heads over a board.} )Bd6 24. h3 $2 {I suppose Fabiano panicked a little in the face of the threat of g4. White can opt for more active possibilities at his disposal.} (24. Qh5 {looks like a natural move to me. If White is afraid of the g4 push then he can play this.} Qe8 (24... Bg6 {is met by} 25. Qh3 {Now} Bf5 {can be replied to by the typical} 26. g4 $1 {gaining time and dislodging the Black bishop.} Bg6 27. Rfe1 f3 28. Re6 {and now Rxg6 is a threat. It seems that once a White rook gets to e6 Black's defences fall apart.} )25. Qxg5+ Qg6 26. Qxg6+ hxg6 27. Nc4 {White still maintains a clear advantage in the ending.} )(24. Nc4 {could be stronger still. Albeit the lines look a bit more like computer variations. It is probably too hard for a human to find them over the board.} g4 25. Qf2 f3 (25... g3 26. Qd2 Qh4 27. h3 $18 )26. Rfe1 fxg2 27. Qxg2 {Black's king turns out to be much more vulnerable than White's.} )Qe8 $1 {Black more or less equalizes now and does not give White any second chance after his mistake.} 25. Nc4 Qg6 {Black manages to mobilize his forces very comfortably. Now he is ready to fight for control in the center and he is a pawn up. So Fabiano decides its time to trade pieces.} 26. Nxd6 (26. Rfe1 Rbe8 )Qxd6 27. h4 (27. Qh5 Qg6 28. Qxg6+ hxg6 {does not lead anywhere for White.} 29. d6 {could just be met by} Rbd8 )gxh4 28. Qxf4 Qxf4 29. Rxf4 h5 {The last accurate move. It secures the g4 square.} 30. Re1 (30. d6 Bg4 31. Rxf8+ Rxf8 32. Rd5 Rf5 $11 )Bg4 31. Rf6 Rxf6 32. Bxf6 Kf7 33. Bxh4 Re8 34. Rf1+ Kg8 35. Rf6 (35. d6 Re2 $11 )Re2 36. Rg6+ Kf8 37. d6 Rd2 38.
