The draw with white pieces might prove costly for Anand especially because the position was clear better. This was second straight draw for the Indian ace in as many games after splitting the point with world number two Fabiano Caruana of Italy in the opener.
Meanwhile World champion Magnus Carlsen of Norway showed no mercy and defeated Michael Adams of England in his legendary torturous way. The Norwegian shot in to sole lead on 1.5 points following the victory as the other two games in the eight-player round-robin tournament also ended in draws.
Levon Aronian could do little against lowest ranked David Baramidze of Germany and had to sign peace while Fabiano Caruana achieved the same result against Etienne Bacrot of France.
 With six rounds still to come, Carlsen is now followed by Anand, Caruana, Aronian, Baramidze and Naiditsch on one point each while Adams finds himself at the bottom of the tables on just a half point from his two games.
Anand faced the Tarrasch defense in his white game in the tournament. The opening has been going through a renaissance lately but the variation played by Naiditsch got in to troubles as Anand had an ace up his sleeves.
Uncorking a new idea on the 13th move, a definite improvement over a recent rapid game between Boris Gelfand of Israel and Hao Wang of China, led to a worse endgame in almost no time for Naiditsch who agreed in the post-game conference that the opening went 'horribly wrong'.
Anand reached a double rook and pawns endgame where black had weaknesses in pawn structure but the Indian could not find the best path to victory even though he remained better a long time. Naiditsch took the chances in his stride to force a draw after 53 moves.
