Prima partita patta: Caruana resiste a Carlsen per 115 mosse!

A Londra nella prima partita del match del campionato del mondo Fabiano Caruana (giocando coi pezzi bianchi) e Magnus Carlsen (giocando coi pezzi neri) hanno fatto subito fuoco e fiamme! La partita si è aperta con una difesa siciliana da parte di Carlsen e la variante Rossolimo da parte di Caruana anziché con la siciliana aperta che prevede uno scambio di pedoni in d4. Tutto ok per le prime 15 mosse ma poi lo sfidante gioca un attacco di cavallo sbagliato e finisce in posizione inferiore, altre due o tre mosse imprecise nei pressi del primo controllo del tempo alla 40a mossa danno un vantaggio decisivo a Carlsen ma il campione non lo concretizza non vedendo un sacrificio di qualità (la propria torre in cambio del cavallo avversario) alla 38a mossa. Da qui Caruana comincia a respirare, il materiale si semplifica notevolmente e si arriva alla 55a mossa a un finale di re, torre e tre pedoni per Carlsen contro re, torre e due pedoni per Caruana (i pedoni sono tutti sul lato di regina), che poi diminuiscono a due pedoni per Carlsen e a uno per Caruana. Un finale che a gioco corretto il campione in carica non può vincere a gioco corretto dello sfidante, ma pur cozzando contro la difesa leonina dell’avversario si intestardisce a voler vincere a tutti i costi prima di accettare finalmente la patta alla 115a mossa (non è record perché Karpov e Korchnoi nella settima partita del 1978 andarono avanti per 124 mosse e lo sfidante, Korchnoj, non vide uno scacco matto in poche mosse) e 7 ore di incredibile battaglia. Qui di seguito lo svolgimento completo della partita coi commenti in inglese su ChessBase di uno dei più promettenti giovani Grandi Maestri, il 20enne polacco Jan-Krzysztof Duda. Foto: World Chess

The position becomes a pretty manoeuvre one, where a stronger player is likely to win. Computers give modest edge for White, but Black has also an easy play on his own: to re-route the knight and then start the pawn offensive on the kingside: 1/2 (44) Caruana,F (2787)-Nakamura,H (2793) Saint Louis USA 2015} )9. 0-0 ({Usually White starts with} 9.

I thought he was going to play Ne6-Nd4 asap, but this is even nicer, as it controls all important squares} 13. Rf2 h6 14. Qd2 g5 $5 {Restraining White pieces. Honestly, I don't know what is White's best bet here, as he lacks visible improvements. It would be lovely to get the h2-knight to f5, but how? Also loosening Black's queenside is not at all that easy. a4 can always be parried by a5, while it's not easy to achieve b4 in a comfortable way. Therefore I think Magnus won the opening duel, and now the Challenger move by move was using a large amount of time} 15. Raf1 (15. Nf1 Qd6 16.

Black intends b5, and if White opens the a-file, Black is always on time with Kb7-Ra8} )(17. e5 {is an easy-to-play sacrifice for everyone but White player.

The kingside is so far locked, and White gains space.} f6 20. b3 Bf7 21. Nd1 ({I would prefer} 21.
