What turned out to be a dull game by Tomashevsky, Anand was in complete control right through but the Russian lived up to his solid reputation too.
This was the only drawn game of round six as players with white pieces ruled the roost in the sixth round.
Armenian Levon Aronian opened the tournament after tormenting Dutch Grandmaster Anish Giri in a fairly one-sided game while Russian Ian Nepomniachtchi was in his element to eke out a fine victory against Shakhriyar Mamedyarov of Azerbaijan.
Luck-less till this round, Peter Svidler of Russia joined the party too at the expense of Li Chao of China while another Russian Vladimir Kramnik handed Israeli Boris Gelfand his fifth defeat in as many games.
Nepomniachtchi became the biggest gainer of the day regaining the sole lead on 4.5
Anish Giri remained in striking distance on four points while Anand, Kramnik and Aronian now share the third spot on 3.5 points apiece, Svidler and Li Chao are not far behind on three points.
With three rounds still remaining in the 200000 US$ prize money tournament, Tomashevsky is in ninth spot on two points while Gelfand with five loses and a solo draw has garnered just a half point.
Anand has been solidly playing the Queens gambit declined with black and it came as no surprise to anyone yet again.
Tomashevsky got nothing when he opted to exchange a couple of minor pieces earlier on and the players were down to a minor piece endgame by move 24th itself. The peace was signed after 49 moves.
