Although all 4 games finished in a draw, players showed an incredible fighting spirit! In the game Ivanchuk-Carlsen – 11.Qa3 turned out to be a novelty, later on Black sacrificed a pawn to simplify and was never in any danger. Svidler got what seemed to be a huge positional advantage against Gelfand out of a 5.Bd2 Gruenfeld (some online sources may call it prosaic, but it never showed :)), with very good attacking possibilities. The 7.f4 & 8. Nf3 plan was new and looks very strong. Perhaps, one improvement is 14.g4 with the idea of Qh3 directly, keeping the d4-pawn protected well for the time being. In Kramnik-Aronian game 11…Qb8 was a new plan, which gave Black a very solid position. White sacrificed a pawn on a2 trying to activate the pieces on the kingside and get attacking chances, but Black managed to give the pawn back and neutralise the threats. One possible suggestion is 27…f6 exchanging part of white’s center, another is 32…Rc2 with the idea of b2. Radjabov played a new move 13…g6 against Grischuk, instead of 13…Ba6 played in the game Nakamura-Gelfand, 2011 or 13…Bf6 played in Wang Hao-Matlakov, 2012. Looks like Black got a very solid play on the queenside and then made an interesting piece sacrifice on c5 to get 3 passed pawns against the N. It was perhaps better to play 36…b4 directly although the N never looked too great against the pawns.

Aronian and Carlsen share 1st – 2nd places with 3.5 points, Svidler is 3rd with 3.

The World Chess Candidates Tournament – London 2013 4th round

Carlsen

The 4th round was again very interesting! Carlsen got a pleasant position with white against Grischuk, and kept on pressing until Black did a couple of inaccuracies (17…f5 and 18…Qg6). Then, Black got into time pressure and lost. Aronian drew Svidler, who played fast and got a very easy game for a pawn, admitting later that he had a rest day thanks to his preparation :). Kramnik got a good position with Black against Radjabov but in the end had to agree to a draw as he didn’t manage to breakthrough. Ivanchuk played the Chigorin Defense against Gelfand and offered many sacrifices until a perpetual check was found :).

So, Carlsen and Aronian share 1st-2nd with 3 points and Svidler is 3rd with 2.5.
