Luke McShane joined world number one Magnus Carlsen in the lead on 8 points from four games after scoring his second win at the 3rd London Chess Classic. McShane defeated David Howell, who blundered in an equal position when he miscalculated a queen sacrifice.
Carlsen drew with Vladimir Kramnik after playing very much in the style of the the former world champion. The Norwegian held a definite edge in a position with rooks and opposite coloured bishops and Kramnik needed all his skill to draw the game by giving up a pawn to exchange the rooks. Nigel Short won a game at the Classic for the first time in eighteen attempts. Short defeated Mickey Adams who seems out of sorts and was slightly worse with the white pieces out of the opening. Short eventually landed both rooks on Adams' first rank and an exchange sacrifice yielded three pawns which gradually advanced to force a win on the 70th move.
The game of the day was a titanic struggle in the sharpest line of the Kings Indian as Vishy Anand and Hikaru Nakamura went all out for the win. Anand went astray from what looked a winning position. The world champion has not won for thirteen games and looks in very bad shape. I have tried to give a few clues in what was a hugely complex game
Scores: Carlsen, McShane 8/4 games, Nakamura 7/4; Kramnik 5/3, Aronian 4/3, Short 3/3 Anand 2/3, Adams 2/4 Howell 2/4
Nakamura has defeated three of the world's best players in this line; Boris Gelfand, Vladimir Kramnik and now the world champion. They have all been remarkable games. Nakamura on Twitter: "Live by the sword and die by the sword. I wonder how many of these games I can play in the KID before I die of a heart attack". Nigel Short once said that even though the King's Indian might be dubious positionally, Black always has counterplay even if he plays imprecisely whereas if White errs, Black's plan leads to mate.

(Dubious as it loses a tempo later when the h pawn goes to h5 but Nakamura didn't care. 13...f4)
14.f3 f4 15.Ba3 Ng6 16.b5 dxc5 17.Bxc5 Rf7 18.a5 h5 19.b6 g4 20.Nb5
White's queenside attack looks more potent than Black's kingside pawn storm at this stage
20...cxb6 21.axb6 g3 22.Kh1
(Also 22.Rxa7 is strong when22...Rxa7 fails 23.bxa7 Nxe4 24.fxe4 Qh4 25.hxg3 fxg3 26.Rxf7)

(25.h3 Bxh3 26.gxh3 Qd7! Wins)

(27.Be6 Nd7 Nakamura 28.Bg1 is fine for White)
27...Bxe6 28.Bxe6 gxh2 29.Nc4? Qe8!
The turning point an unusual motif Qe8-b5 causes major problems
