Caruana Scores First Win

Fabiano Caruana scored his first win today at the Tashkent Grand Prix. His opponent Boris Gelfand blundered badly in a position which was seemingly equal:

Exciting Draw in Round Four

All the games ended peacefully in round four of the Tashkent Grand Prix which does not necessarily mean that there was no show for the spectators.

Was the Initiative Enough?

Round three in Tashkent saw three decisive games. In the following one White sacrificed a pawn early in the opening. Was the sacrifice good enough for an advantage? Or at least for a level game?

Maxime's Revenge

Starting from yesterday I will do regular analyzes on the most interesting event for chess.com
Currently the attention is focused on the Grand Prix tournament in Tashkent which gathers together some of the top players in the world.
The game that everyone expected was between Maxime Vachier-Lagrave and Fabiano Caruana. The French GM is showing constant progress in his play but was defeated twice recently by Caruana (in Saint Louis). Maxime also had a birthday that day and he obviously decided to take care of the present himself.

The solution of the problem would be the proper equipment with a base of knowledge. You do not need to know every single endgame by heart. It is hardly possible (except perhaps for a genius like Ivanchuk) but more importantly it is not worth memorizing countless endgames which are very unlikely to happen.
On the other hand each player should owe an existence minimum of exact positions in every major endgame (pawns above all but also knight/bishop/rook/queen) endgames. This will help the players a chance to orientate in most of the situations, will suggest them which pieces to trade and which to keep and naturally will support the calculation.
Best of luck in building your own memory library!

Know How in the Pawn Endgames (1)

The knowledge of exact positions is the cornerstone in the understanding of the pawn endgames.
The pawn endgames have their own specifics. Contrary to the other endgames where we can use approximate evaluations like slightly better/worse or much better/worse without definite conclusion, in the pawn endgames we use only three evaluations- win/draw/loss.
The lack of material enables us to calculate the lines till the end but this is easier said than done. At the end of the game players are usually tired and tend to make more mistakes. The time troubles also do not contribute to the proper calculations.
To sum the things up- pawn endgames can be easily compared to mathematical task where you have only one true answer. In order to find this answer the knowledge of a concrete theorem is needed in mathematics, while in chess that would be the knowledge of a concrete exact position.
Let's have a look of a case where one of the opponents is lacking essential exact knowledge. The following game was played at the first Metropolitan open tournament in Los Angeles three years ago. The player who has the white pieces is a strong national master Mikhail Langer. His opponent is a young and promising IM from Canada, Raja Panjwani. It was actually Raja who showed me the game immediately after it was over. It is a strange coincidence as you will see in a moment. In the diagrammed position White chose the natural looking:
