Your judgement, please - Pt. 50
Su valoración, por favor
El rey en el centro es un tema clásico. En esta partida clave de la Bundesliga Alemana, el actual Campeón del Mundo sub-20 había sacrificado un peón para abrirse paseo hacia el rey negro, lo cual fue respondido con 16...f6. ¿Cuál es su veredicto sobre esa continuación?
A) Es un error: las blancas podrán penetrar la posición de manera decisiva.
B) Una buena jugada: las negras repelen al alfil y consolidarán su peón de más.
C) Mucho ruido y pocas nueces. La posición sigue equilibrada.
La solución está aquí, pero antes de mirarla le sugerimos que reflexione sobre el problema
Las negras han jugado 16...f6. ¿Cómo valoraría Ud. esta continuación?
A) Es un error, las blancas podrán penetrar la posición de manera decisiva.
B) Una buena jugada, las negras echan atrás al alfil y consolidarán su peón de más.
C) Mucho ruido y pocas nueces. La posición sigue equilibrada.

Zugzwang
10.02.2010 – Although there are of course beautiful examples of zugzwang in the middlegame, it is much more a motif from endgames, many of which could not be won without zugzwang. Even when there is a clear superiority in material, as for exampe in the duel between a rook and a bishop, it is often only possible to make progress by employing zugwang. Here is a typical example. After 68.Kb5 Black could, with the correct continuation, have retained his chances of a draw. What that was and the instructive winning method used by White after 68...Bc5? are things you can find out from Karsten Müller's analysis in ChessBase Magazine Online.
Position after 68.Kb5. How can White make progress after 68...Bc5? ?

Sherlock Holmes chess
06.02.2010 – A very original sequence happened in this Sicilian encounter from the recently finished festival in Wijk aan Zee. The black knight is attacked, but onto which square it should go now is only one question (A).
The other interesting issue is: what was actually White's last (and best!) move (B),
as a reaction in turn to which black move (C)?
What do you think, Watson?
The solution is here, but first ponder over it with a larger version of the diagram.

Fire on board...
04.02.2010 – ... has become Alexei Shirov's trademark. In the tournament in Wijk aan Zee, which Shirov started with five wins in a row, the 37-year-old chess magician from Riga once more justified this reputation. In many middlegame positions he managed to put his opponents under pressure with inventive attacking play. And even in the endgame, one always has to take into account that Shirov might set the board on fire. This happened in the eleventh round in his game against Vladimir Kramnik, where he played 35.c5! in the diagram position. GM Karsten Müller has analysed the endgame for ChessBase Magazine Online.

The wrong choice of ending
27.01.2010 – In round 7 in Wijk, Nigel Short was within touching distance of a win over Ex-World Champion Vladimir Kramnik. In the position in the diagram he had to decide whether to exchange queens or to gobble up another pawn with Qxc5. Short chose 50.Qxc5, but after 50...Be6! 51.g4 Bxf5 52.Qxf5 Qb2+ the activity of the black queen turned out to be the decisive drawing factor, despite Black being two pawns behind. But how should the minor piece ending after 50.Qxf6 gxf6be evaluated? Can the extra pawn be made to tell in the struggle of knight against bishop? Yes, says GM Karsten Müller in ChessBase Magazine Online.

Wijk aan C
28.01.2010 – Seeing all these superstars at the Corus Tournament 2010, one can easily forget that also the C-group provides a wealth of highly interesting chess. For example this game, where White after Black's last move 23...Bg7-f6 had to parry the attack on his queen. The strike 24.Rxf5 in your opinion leads to what?
A) advantage for White;
B) balanced play;
C) advantage for Black.
The solution is here, but first ponder over it with a larger version of the diagram.

A stunning exchange sacrifice...
24.01.2010 – ...in the Marshall Attack was unleashed by Peter Leko in the 4th round in Wijk aan Zee versus Lenier Dominguez. Playing black, here he was facing the question of whether it would be advisable to immediately occupy the long diagonal with 23...Bc6 despite the riposte 24.d5, blocking it with tempo. What do you think?
A) this wins for White;
B) Black prevails;
C) the position eventually remains balanced.
The solution is here, but first ponder over it with a larger version of the diagram.
How do you assess the position after 23...Bc6 24.d5?
