Torneo de Linares 2009: Anand y Carlsen, ¡frente a frente! (7)

Terminó la primera vuelta del Torneo de Linares. La clasificación final justo en el ecuador del evento está como sigue:

1 5.0 GM Alexander Grischuk RUS 2733

2 4.0 GM Vassily Ivanchuk UKR 2779

3 4.0 GM Magnus Carlsen NOR 2776

4 3.5 GM Levon Aronian ARM 2750

5 3.5 GM Viswanathan Anand IND 2791

6 3.0 GM Leinier Dominguez CUB 2717

7 2.5 GM Teimour Radjabov AZE 2761

8 2.5 GM Wang Yue CHN 2739

Mientras el comienzo de la segunda vuelta está previsto para este sábado, vemos que Carlsen le saca medio punto de ventaja a Anand, pero sin embargo de nuevo hoy, la partida más vistosa de las que disputaron ambos en esta séptima ronda, correspondió a Anand, que entabló con el líder Grischuk en un complejo encuentro plagado de sutilezas en el medio juego.

Así pues, en nuestro marcador particular el campeón del mundo domina a su rival en el aspecto “artístico y creativo” por el siguiente resultado:

Anand: 5 – Carlsen: 2,5.

¡Vivir para ver!.

Anand,V (2791) - Grischuk,A (2733) [E84]
Linares Linares, 26.02.2009
[Jimenez,A sobre notas de ICC y Rybka]

1.d4 Cf6 2.c4 g6 3.f3 Un experto en la Defensa Grunfeld, el GM polaco Michal Krasenkow ha analizado a fondo esta jugada 3.f3, con actuales ejemplos de la alta práctica magistral, evaluando que este sistema blanco no causa problemas a las negras. Grischuk desea pasarse por trasposición a esquemas de la Defensa India de Rey, que entonces será Ataque Samisch. 3...Ag7 I wonder what Anand prepared after 3.f3 d5 . Recently I looked at these lines and it all seems great for Black. especially after Vallejo-Navara. 4.e4 d6 5.Cc3 0-0 6.Ae3 a6 7.Cge2 Cc6 8.Dd2 Tb8 Diagram

Estamos en el "corazón" de la línea conocida como Samisch-Panno. 9.Tc1!? Anand opta por una de las tantas jugadas posibles en esta "jungla" de variantes. [9.h4; 9.Cc1; 9.g4; 9.Ah6; 9.Tb1; 9.a3; 9.0-0-0; 9.d5; 9.a4; 9.Cg3; 9.Td1] 9...e6 without 0-0-0 available h4-h5 is risky [9...Te8; 9...Cd7] 10.b3 Cd7N [10...Ce7 11.Cg3 Ce8 12.Ae2 c6 13.0-0 b5 14.f4 f5 15.e5 g5 16.exd6 Dxd6 17.fxg5 e5 18.dxe5 Dxd2 19.Axd2 Axe5 20.Af4 Axf4 21.Txf4 Cg7 22.Tf2 Cg6 23.cxb5 axb5 24.Af3 Ce5 25.Te2 Cxf3+ 26.gxf3 Ce6 27.Ch5 Rf7 28.h4 h6 29.gxh6 Th8 30.Td1 Txh6 31.Cg3 Cf4 32.Te5 Ae6 33.Td4 Txh4 34.Cxf5 Tg8+ 35.Rf2 Th2+ 36.Re3 Cg2+ 37.Re4 Th1 38.Td2 Te1+ 39.Te2 Ad5+ 40.Rd4 1-0 Van der Sterren,P (2535)-Nijboer,F (2475)/Netherlands 1996/CBM 054] 11.h4 h5 12.g3 Whites position seems fairly dominant, he has more space and better pieces, g5-square weak too. 12...Ce7 Black intends b5 now i guess, but that will hardly solve anything, just bg2 and 0-0 and white is clearly better. 13.g4 hxg4 14.fxg4 Maybe the crazy nf6 g5!?. Maybe e5 for black now. 14...Cf6 Diagram

15.g5 Actually this bh3 e5 h5 is looking really promising for white in my opinion, h6-h7+ big threat and if black takes with knight on g4 white can eliminate important defensive piece. [15.Ah6 Cxg4 16.Axg7 Rxg7 17.h5 Th8 18.Dg5 Ch6 and maybe black holds, though it seems like interesting idea; 15.h5 Cxg4 16.h6 Af6 17.e5 dxe5 18.Ce4 actually doesn't look half bad, now that I'm taking it more seriously. And there are pretty bad for black: 18...Rh7 (18...exd4 19.Cxf6+ Cxf6 20.Axd4; 18...Cf5 19.Cxf6+; 18...Cc6! Rybka. Con ventaja.) 19.Ah3; 15.Ah3!? e5 16.h5 interesting line and life seems difficult for black there. 16...Cxg4 17.Axg4 Axg4 18.h6 Af6=/+ Rybka.] 15...Ch5 looks pretty forced [15...Cg4 and if black manages to exchange e3-bishop, he will go for f6 or f5 soon 16.h5 Cxe3 17.Dxe3 gxh5 18.Dh3= Rybka.] 16.Ag2 and bf3-xh5 is coming, looks really risky for black. Not: isn't such a huge threat since then Black can play ...Ng6 and ...Bg4. 16...e5 Yes, black is fine.... he was probably fine after 13. g4 in general. I dont like d5 idea, white knight could be well placed in d5 in many lines, as opening c-file for white isnt ideal for black. 17.Af3 Why is bf3 stupid?. If black manages bg4 whites kingside play will come to complete stop and his entire preceding play looks stupid. 17...b5 looks too slow in my opinion, it doesnt do anything. White will concretely try to stop his king from being massacred in the lonely center. 18.dxe5 Axe5 19.Cf4 [19.Axh5 gxh5 20.Cd5 It seems that black must take on d5 in view of nf6+ threat. 20...Cxd5 21.cxd5 whites king is weak there, but black has serious positional defects.] 19...Axf4 Tiempos: 00:44:00 - 00:18:37 . 20.Axf4 Well i think black must take on f4 twice otherwise whites darksquared bishop will be too strong. 20...bxc4 21.bxc4 Could be that Ws advantages on the K-side more than compensates for his structural weaknesses. 21...Ae6 22.Cd5!? black has to take on d5 with either piece and both takes have some problems. The white king seems safe for now. The more i look at this better it looks for white, difficulties with king for black. 22...Axd5 [22...Cxd5 23.cxd5 Ad7 24.Axh5!+/= (24.Ae3!? con idea de Ad4.) ] 23.cxd5 Dd7 Diagram

Makes some sense but there some long term problems with both knights having problems finding good square. 24.0-0 [24.Axh5 gxh5 25.0-0= (25.De2 Cxd5!=/+ (25...Cg6!?) ) ; 24.Ae3 c6 25.Ad4 cxd5 26.Aa1=/+ (26.Axh5 gxh5 27.g6 brutal deluxe.) ] 24...Cxf4 25.Dxf4 c6 doesnt seem like white has much anymore, and he could easily get some positional problems with that bishop 26.h5 cxd5 27.h6 De6 28.exd5 Cxd5 29.Axd5 [29.Dd4 De3+ 30.Dxe3 Cxe3 31.Tfe1 Cf5 white has definite compensation for pawn but its bit unclear if theres anything more] 29...Dxd5 30.Df6 De5 31.Dxe5 dxe5 32.Tc5 Tb5 [32...Tb5 33.Txb5 axb5 34.Te1 Te8 35.Tb1 Tb8 36.Te1 Te8 37.Tb1=] 1/2-1/2

Un saludo!,
