Un'altra difesa siciliana con la variante Rossolimo e un'altra patta, la quinta su cinque partite del Mondiale di scacchi di Londra tra Magnus Carlsen e Fabiano Caruana. La novità però, almeno per questo match, è che lo sfidante italostatunitense coi pezzi bianchi stavolta alla quarta mossa non scambia il proprio alfiere delle caselle chiare col cavallo avversario ma opta per la mossa più giocata in quella posizione, e cioè l'arrocco corto sul lato di re. La partita è quantomeno molto più movimentata (ma bastava molto meno...) della quarta giocata martedì, col Bianco che a un certo punto ha due pedoni di vantaggio, oltretutto dopo averne dato in pasto uno all'avversario alla sesta mossa (attacco Gurgenidze), e il campione in carica col Nero verso la fine ne ha uno ma la patta per i motori scacchistici è evidente fin dalla 18a-20a mossa. Entrambi sbrogliano ogni situazione giocando sempre le mosse giuste e gli scacchi a raffica di Caruana al re nero, entrato abbondantemente nella metà campo avversaria (quando il materiale è poco sua maestà diventa un pezzo molto forte!), non preoccupano minimamente Carlsen, dopo l’ultimo dei quali, col pedone g bianco, viene sancita l’ennesima patta alla 34a mossa quando i due giocatori hanno quasi tutto il materiale sul lato della scacchiera dei rispettivi monarchi: re, torre, alfiere delle caselle scure e tre pedoni per ciascuno. Oggi la sesta partita in cui Carlsen avrà il Bianco così come nella settima, i due ragazzi prodigio si inventeranno qualcosa di clamoroso?

1. e4 {Not surprisingly, Caruana sticks to his usual first move.} c5 {Again a
Sicilian by Carlsen, which is logical considering the fact that Black was
doing quite OK in the previous games.} 2. Nf3 Nc6 3. Bb5 (3. d4 cxd4 4. Nxd4 {
I would be very interested in which variation Carlsen would chose here, and I
hope we will see this in one of the upcoming games.} )g6 4. 0-0 $5 {
White diviates from games 1 and 3, where he played Bxc6. This logical move is
also very popular, and played many times on the top level.} Bg7 5. Re1 e5 {
As in the earlier games, Magnus likes to put his pawn on e5 as early as
possible, not allowing e4-e5.} 6. b4 $5 {Played instantly by Caruana and
clearly his preperation. This move made me happy to watch, as it looks sharp
and interesting. The most dangrous scenario for Carlsen would now to be
unprepared for this move. But actually he had faced it before!} (6. c3 {
is how White usually continues when they don't take on c6.} )Nxb4 {
Played after only a few minutes thought, which means that Carlsen was probably
ready for this line.} (6... cxb4 {is what Carlsen answered as a young kid many
years ago, and the move which seems most logical. The game followed:} 7. a3 Nge7 (7... b3 {Played recently by Grischuk with success against Bacrot in
rapid. The point is just to sacrifice the pawn back and keep the a-file closed,
and then to just develop.} 8. cxb3 Nge7 9. Bb2 0-0 10. d4 (10. b4 {0-1 (48)
Bacrot,E (2708)-Grischuk,A (2761) Paris 2017} d5 $1 $146 {And Black is first
to strike in the center with a good game.} )d5 {with a complicated battle
} )8. axb4 0-0 9. Bxc6 bxc6 10. Bb2 d6 11. d4 f6 12. Nbd2 $14 {Where Black was
quite passive and the White posistion looks very nice. ½-½ (52) Stellwagen,D
(2524)-Carlsen,M (2553) Wijk aan Zee 2005 CBM 105 [Finkel,A]} )7. Bb2 {Simply
developing the bishop to a good square and threatening a pawn. Other moves do
not make much sense.} (7. c3 Nc6 8. d4 exd4 9. cxd4 Nxd4 $1 $17 )a6 {
Again played quite fast, probably meaning that Carlsen was just spending some
time remembering his analyses.} (7... Qc7 {is also a move to consider, just
protecting the pawn.} 8. c3 Nc6 9. d4 d6 {I would be curious to see what
Caruana had planned here, but it looks easier to play White as he has the
attacking chances.} (9... Nf6 10. dxc5 $14 { looks nice for White} )10. d5 a6 11. Na3 Ke7 $13 {With an unclear and very sharp game. I believe that
White has compensation for a pawn at least, but if he is better or not remains
a question. Black went on to win a fighting game in 0-1 (44) Rapport,R (2676)
-Granda Zuniga,J (2665) Camarinas 2013} )8. a3 {The only challenging move,
still in Caruana's preperation.} (8. Bf1 $2 {Just does not make sense, and
after} Nc6 {White cannot play Bxc6 and Black remains a pawn up.} )axb5 {
Played after 5 minutes of thought, and I believe it was still in his
preperation. This leads to some simplifications, which is usually beneficial
for the defending side:} (8... Nc6 9. Bxc6 dxc6 10. Nxe5 Nf6 11. Nf3 { Was also a possibility, but I would chose White as he has the better
structure here.} )9. axb4 Rxa1 10. Bxa1 d6 {Defending the important e5 pawn.} (10... cxb4 11. Bxe5 $1 {Does not look so healthy for Black} Bxe5 12. Nxe5 Ne7 13. Qe2 $14 {} )11. bxc5 Ne7 {Finally Black gets time to develop his
knight and is preparing to get the king to safety. White must try to create
something fast, as if Black gets one more developing move he has a perfectly
fine posistion with the bishop pair.} 12. Qe2 {Forcing the play. Still blitzed
out by Caruana and his prep, although it does not lead to much:} (12. cxd6 Qxd6 13. d4 {Looked very logical to me, opening up the game before Black has
castled.} exd4 14. Bxd4 (14. e5 Qb4 15. Nxd4 (15. Qxd4 Qxd4 16. Nxd4 b4 {
Black will castle next and have nothing to worry about.} )0-0 { Black has activity and a nice posistion} )0-0 15. Bxg7 Qxd1 16. Rxd1 Kxg7 {A critical posistion. The question remains if
White can create something against Black's doubled pawns in this ending, but
probably Black is too active.} 17. Na3 (17. Nd4 b4 18. Nd2 Rd8 $132 )b4 18. Nc4 Nc6 $11 )b4 {The only move which saves the pawn.} (12... 0-0 $2 13. Qxb5 $16 {Would just lose a pawn.} )13. Qc4 {Renewing the threat and
stopping Black from castling.} (13. c3 Nc6 14. cxb4 dxc5 15. bxc5 Qa5 {} 16. Nc3 Qxc5 )(13. Qb5+ Nc6 { and Black should be OK as
he gets to castle next!} )Qa5 $1 { Forcing the
queens off:} (13... Nc6 14. d4 $1 {Seems dangrous for Black:} exd4 15. Nxd4 Bxd4 (15... Nxd4 16. Bxd4 {would lead to collapse of the Black posistion} 0-0 17. Bxg7 Kxg7 18. Rd1 $16 { and White wins a pawn.} )16. Bxd4 Be6 (16... 0-0 $2 17. cxd6 Qxd6 18. Bc5 $18 {loses the exchange.} )17. Qb5 0-0 18. Be3 {White has a risk-free advantage.} )14. cxd6 (14. Bb2 $2 Be6 $17 {} )Be6 (14... Nc6 15. d4 $1 $36 Qxa1 16. d5 { Looks
only fun for White} )15. Qc7 (15. Qe2 Qxa1 16. dxe7 Qa6 $1 { Black
is doing great} )Qxc7 16. dxc7 Nc6 $11 {Protecting the important e5-pawn
before planning to eat the pawn on c7 with Kd7. I guess that probably around
here the notes of the players ended, and they are on their own. We have
reached a position where White has a healthier structure, but at the same time
Black has the bishop pair and some activity - I would say enough counterplay
for being OK. Still White needs to spend some tempi to bring the b1-knight to
life. Black should be happy about the outcome of the opening!} 17. c3 {
Prepares to bring the b1-knight into the game.} (17. Rd1 { What I
was expecting. Simply preparing to open up with d2-d4.} Kd7 18. d4 b3 $1 {
A surprising move, but it solves the problems mainly because of the activity:} (18... exd4 19. Nxd4 Nxd4 20. Bxd4 Bxd4 21. Rxd4+ Kxc7 22. Rxb4 Kc6 {and the
question is if Black has enough compensation for the pawn, but it is clear
that White is in the driver's seat at least:} 23. Nc3 Ra8 24. Kf1 $14 {And
Black is the one who has to play precisely in order to make a draw.} )19. Nxe5+ (19. dxe5+ Kxc7 {} 20. cxb3 Bxb3 $44 {Black is too active and
has a nice b-pawn. I would definetly take Black in this posistion.} )(19. cxb3 Bxb3 $15 {} )Kxc7 $1 (19... Nxe5 20. dxe5+ Kxc7 21. cxb3 Bxb3 22. Rc1+ $14 {} )20. cxb3 Ra8 {} 21. Nd2 (21. Nc3 Bxb3 $1 )Bxe5 22. dxe5 Ra2 {Although Black is two pawns down, he has
enough compensation: Extremely active and good king, and the b3 pawn should
fall at some point. The White pieces are rather stuck.} )Kd7 (17... b3 $2 18. d4 $18 { is a killer!} )18. cxb4 Ra8 {Annoying move. Although
he could take on c7, it makes more sense to get the rook to a better square
first.} 19. Bc3 (19. Nc3 $2 Nxb4 $1 )(19. Bb2 Ra2 $1 )Kxc7 {Black
remains a pawn down, but still White did not solve the b1-knight problem, and
Black has a much better king + bishop pair. Carlsen definetly has an easier
posisiton here} 20. d3 {Gets a new square for the b1-knight.} (20. Ng5 {
Actually the only move that reaches equality. But quite desperate and not so
logical..} Bc4 21. Nxh7 {Obviously an ice-cold way for a human to play...} )(20. Rc1 Kd7 $15 {} )Kb6 $6 (20... b5 $1 $15 {
The only chance Carlsen had in the game to be better. The b4-pawn is weak, and
this just seems as a more comfortable posistion to play for Black. At least
Caruana would have to be precise here. Usually Carlsen is always taking these
small chances when he gets them, so I'm a bit curious what he missed. As the
game continued, there was not much happening.} 21. Kf1 (21. Bd2 Rd8 $1 {
} 22. Nc3 Rxd3 23. Nxb5+ Kb6 24. Nc3 Nd4 $17 {maybe the line Carlsen
missed?} )Ra4 22. Bd2 Nxb4 )21. Bd2 $1 {Preparing Nc3, and kind of
profylactic against Kb5.} (21. Ng5 Kb5 22. Nxe6 fxe6 23. Kf1 Bf8 $1 )Rd8 (21... Kb5 $6 22. Nc3+ Kxb4 23. Rc1 {} (23. Na4+ $1 ))22. Be3+ Kb5 (22... Kc7 23. b5 $1 )23. Nc3+ {White finally gets to develop his knight and
the posistion gets simplified:} Kxb4 24. Nd5+ $1 {Basically a draw is forced.} Bxd5 (24... Kb3 25. Rb1+ {} )25. exd5 Rxd5 26. Rb1+ Kc3 27. Rxb7 Nd8 $1 28. Rc7+ Kxd3 { Black is a pawn up, but White is too active and
the d8 knight is stuck to protect f7. One of the pawns will be lost.} 29. Kf1 h5 (29... e4 $4 30. Ne1# {Would be a funny mate!} )30. h3 Ke4 31. Ng5+ Kf5 32. Nxf7 $11 Nxf7 33. Rxf7+ Bf6 34. g4+ {Black offered a draw as there is nothing to play
for with 3 against 3 pawns on same side.} 1/2-1/2
