Torneo Dortmund 2010

Dortmund 2010: Ponomariov supera a la oposición

En la octava ronda, el ucraniano Ruslan Ponomariov esta a dos rondas de completar lo que ha sido una actuación virtuosa.
Mientras que sus adversarios no habían podido tener cualquier momento fuera de la parrilla de salida, que consolidó su liderato superando superior al alemán Arkadij Naiditsch en un partido fuerte, que concluyó con técnica impecable.

Le Quang jugando una calmada catalána abierta contra Mamedyarov. Con ambos empatados en el segundo, a medio punto del líder, no había duda de que se juega mucho, en un final bastante tranquila, al parecer sólo intentos de suicidio se mecía el barco lo suficiente para cualquier persona a hundirse, pero ambos mantuvieron sus nervios.

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 0-0 5.Bd3 d5 6.Nf3 c5 7.0-0 Nc6 8.a3 Bxc3 9.bxc3 dxc4 10.Bxc4 Qc7 11.Bb2 e5 12.h3 e4 13.Nd2 b6 14.Bb5 Na5 15.c4 cxd4 16.Bxd4 Qe7 17.c5 a6 18.Ba4 bxc5 19.Bc3 Nb7 20.Bc6 Ra7 21.Qb1 Qc7 22.Bxe4 Nxe4 23.Nxe4 Qc6 24.Ng5 Qh6 25.f4.

25...Nd6?! The simplest way to kill White's initiative here, was to just exchange queens with 25...Qg6 Possibly the German player entertained ambitions for more, but considering how poorly placed his pieces are (the fianchettoed knight is hardly textbook) it was time to undertake safety measures. 26.Qxg6 hxg6 27.e4 f6 28.Nf3 Nd6 and Black is ok. 26.Qb6 Rb7?! Better was 26...Rd7 27.Qxc5 Qg6 28.Rad1 Re8+/= The difference is that with the move played, Black gains a few tempi harrassing White's queen, but doesn't gain much for it. With 26...Rd7 would finish developing his pieces and regroup to fight for the center. 27.Qxc5 Rb5 28.Qc7 Rb7 29.Qc6 Nb5 30.Qxh6 gxh6 Black is in a world of pain: down a pawn, shattered structure, and still uncoordinated. 31.Ne4 f5?

This tactical mistake will quickly put an end to Black's misery. The Ukrainian makes no mistakes and is ruthless in his efficiency. 32.Nf6+ Kg7 33.Be5 Rxf6 34.Rfc1! Bd7 35.Rab1 Ra7 36.a4 Nd6 37.Bd4 Ra8 37...Rb7? 38.Rxb7 Nxb7 39.Rc7+/- 38.Rd1 Ne4 39.Rb7 Rd8 40.Be5 Kg6 41.Rdxd7 Rxd7 42.Rxd7 Rc6 43.g4 Rc1+ 44.Kg2 Rc2+ 45.Kf1 Not 45.Kf3?? Rf2# 45...Nd2+ 46.Ke1 It is over. After 46.Ke1 Nf3+ 47.Kd1 Nxe5 White was threatening Rg7 mate. 48.Rd6+ Kf7 49.Kxc2+- 1-0
