Wang Hao is still leading the Biel Chess Festival after round 6, but runner-up Anish Giri is just 2 points behind the leader. On Saturday the Dutch grandmaster defeated Victor Bologan in a game that lasted just over seven hours. Long before this result, the games Nakamura-Carlsen and Bacrot-Wang Hao had ended in draws. Bologan, who substituted for Alexander Morozevich after round 2, thus lost three games in a row and faces Carlsen tomorrow, when the other players enjoy a rest day.

The 6th round of the GM tournament in Biel started slightly disappointingly. A game between Hikaru Nakamura and Magnus Carlsen always generates certain expectations, but in this particular case the two top GMs played arguably the least interesting game so far in the Swiss town. But that's also chess, as Nakamura pointed out in his traditional post-game tweet:

When your opponent finds all the right moves, the game will inevitably be a draw. Pretty standard result going into the rest day.

Like Carlsen, tournament leader Wang Hao used the Grünfeld to draw with Black. His opponent Etienne Bacrot said afterwards that he was happy to see his opponent's third move.

I was afraid I would lose four games in a row in the King's Indian!

Obviously the game of the round was the one between Victor Bologan and Anish Giri, and not just because it was the only decisive result. At move 16 the Dutchman won a pawn and finally, at move 92 and after seven hours (and a few minutes) of play, the game. Giri's tweet was short and sweet:

Won. Happy. Tired.
