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.

What do you think?
A) this wins for White;
B) Black prevails;
C) the position eventually remains balanced.

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?

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.

B) White gets the advantage;
C) the result is a draw by perpetual check.

Entrevista de Magnus Carlsen a revista Time

Magnus Carlsen en 'Time'
En muy poco tiempo, la prestigiosa revista "Time" ha publicado dos reportajes sobre Magnus Carlsen. El 25 de diciembre publicó una entrevista con la súper estrella de ajedrez en la cual nuevamente demostró un fino sentido de humor. Preguntado por el trágico destino de los que otrora niños prodigios Morphy y Fischer, el noruego de 19 años opinó que es fácil dejarse llevar por completo por el ajedrez, pero que por ahora no tenía la sensación de ir a volverse loco. A Magnus el ajedrez no le parece un arte, sino un tipo de combate. La meta para él siempre es vencer a su oponente y encontrar siempre las jugadas más desagradables posibles para el rival. Se suele entrenar exclusivamente en el ordenador. "A veces nos vienen a visitar a casa y piensan que deberíamos tener muchos tableros de ajedrez. Entonces les contesto: 'Puede que en alguna parte tengamos uno, pero ahora no sé muy bien, dónde está'". Ayer "Time" publicó otro retrato del noruego, titulado "A Bold Opening for Chess Player Magnus Carlsen" (Una apertura valiente para el ajedrecista Magnus Carlsen) escrito por Eben Harrell, que pueden leer en inglés en la web de Time...

Barriers
05.01.2010 – An active king often plays a decisive part in rook endings. If it can support a passed pawn in its advance, then the king and pawn form an extremely deadly duo. So the ability of the rook to cut off the king horizontally or vertically from one of the theatres of war and thus to restrict its activity is an important weapon in the arsenal of endgame technique. Karsten Müller has selected a recent endgame in which the theme of the barrier and the struggle against it are in the foreground.

The strongest players of all time

Retirado do site Chessbase.com.

05.01.2010 – According to the current FIDE rankings Magnus Carlsen is the strongest player in the world. But his rating of 2810 is not the highest ever. That was achieved by Garry Kasparov, who in the July 1999 FIDE list reached 2851 points. Two other players have at some stage had higher ratings than Magnus. Here's a list of all Super-GMs (over 2700) and their top ratings.

Top Ratings of Super-GM

Three years ago Przemek Jahr of Pila, Poland, sent us a list of all players who had reached a rating of 2700 or higher, giving their highest ever ratings and the year and the FIDE list in which it was achieved. Chess fan Kostantin Ikonomovski of Jankovec, Macedonia, has been updating this list meticulously and sent us the latest version that incorporates all list up to the January 1st 2010 FIDE rankings.

Konstantin is a member of the amater team of Alkaloid for many years; "That meant that I used to have four extra vacations every year on company expences," he writes, "always in some wonderful places throughout the former Yugoslavia. I carry beautiful memories of this."

Top ten players of all time

The highest rating ever, by Garry Kasparov, is 38 points more than any other player in history. Five players have crossed the 2800 mark, five players have come within twenty points of it. Here's the complete table.

The huge space advantage...
01.01.2010 – ... of White in the diagram position was obvious, yet with 24...Qb6 Black had produced the double threat 25...Bxa3 and 25...Nxe5 26.Bxe5 Rxe5. How would you assess the position now?
A) White can win material;
B) he is optically better, but there is nothing concrete;
C) looks are deceptive, the first player is on the defence.

The solution is here, but first ponder over it with a larger version of the diagram.
