25/03/2018 – La duodécima ronda fue dramática porque cambió por completo el foco de las previsiones sobre el próximo retador de Magnus Carlsen. Sergey Karjakin derrotó al hasta ahora líder, Fabiano Caruana en una partida muy dinámica, con un fantástico sacrificio de calidad y ahora se ha apuntado al mando, con la mejor valoración de desempate, de momento. Shakhriyar Mamedyarov perdió contra Ding Liren. Hoy es día de descanso en Berlín. La ronda 13 se disputará mañana, lunes 26 de marzo. | Foto: World Chess

Bxd5 $3 {Excellent decision from Sergey, who really knows how to handle decisive games. The value of this move lies in creating an extremely unpleasant situation for Fabiano. Objectively Black may not be much worse, but he finds it hard to develop any play.} ({Of course, not} 17. Qxd5 $2 Qxd5 18. Rxd5 Bxf3 19. Rxd8+ Rxd8 20. gxf3 Rd5) 17... Bxd1 18.

Eventually White can strike with b2-b4 or advance his h-pawn.} g5 $6 {I can understand why Fabiano played this move, but it's just not good enough.} 24. Ka2 Ree7 25. Qf3 Kd8 26. Bd2 Kc8 27.

Qg4 Re5 37. h4 Ke7 38. Rd2 {Not a bad move,} ({while both} 38. Qg3 Qf5 39. Rf3) ({and the immediate} 38. Bxf7 Qf5 (38... Qf5) 39. Rxd7+ Kxd7 40.

En noviembre: el Campeonato del Mundo en Londres 2018 "London2018.worldchess.com"
La página web london2018.worldchess.com de World Chess ofrece información adicional acerca de las entradas y anuncia que habrá un "paquete particular" y un "programa de referencia" y que estarán dipsonibles dentro de dos meses, apróximadamente.
No es la primera vez que Londres alberga un duelo por el Campeonato del Mundo. En el año 2000, Vladimir Kramnik arrebató la corona mundial a Garry Kasparov allí. Curiosamente, Vladimir Kramnik será uno de los Candidatos, 17 años más tarde. Los patrocinadores rusos sin duda se habrán llevado una ilusión cuando los organizadores anunciaron que el jugador de libre designación era Kramnik, hace un mes.
Además, la ciudad de Londres también fue sede del encuentro del duelo por el título mundial entre Garry Kasparov y Nigel Short en 1993 y allí se jugó parte del duelo entre Anatoly Karpov y Garry Kasparov en 1986.
