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.

El caballo es mal defensor
Si tiene que actuar él solo, el caballo muchas veces tiene problemas en el final para defender uno de los flancos. Si los peones no tienen una posición muy particular que le favorezca, normalmente no suele servir para ello. A eso se debe el sacrificio de pieza 35.Txc4!? Txc4 36.Cxc4 Rxc4 37.Re4!, jugado en la partida Lock vs. Webb en el torneo magistral de Hastings. Las blancas causaron serios problemas prácticos al oponente negro. ¿Cuál es su valoración de la posición tras dicha secuencia? ¿Aún podrán empatar las negras o triunfarán los peones del bando blanco? El GM Karsten Müller ha analizado la posición para ChessBase Magazine Online...- Análisis de la partida Lock vs. Webb por el GM Karsten Müller... - DVDs de entrenamiento de finales en la tienda de ChessBase...

To sacrifice or not to sacrifice?!
19.01.2010 – A complicated position arose during time trouble in Tomashevsky (2708) vs Fier (2653). The pawn structure leaves us in no doubt: it was a King's Indian. The sacrifice 35...Bxg4 is on the cards, but calculating through all the consequences accurately is hardly possible. What does your intuition tell you?
A) The sacrifice is unsound. Black does not get sufficient compensation.
B) The sacrifice is playable. The position remains balanced.
C) 35...Bxg4 decides the game in Black's favour.
The solution is here, but first ponder over it with a larger version of the diagram.

'The best game of the last 20 years'...
16.01.2010 – ... Jan Timman wrote about this encounter between two absolute top grandmasters of the 70s and 80s. Here Black played 21...Bb5 and later succumbed in a remarkable attack. How would you assess the position after 21...Nxc7 instead?
A) The second player maintains his plus pawn without risk;
B) White gets the advantage;
C) the result is a draw by perpetual check.
