The playing hall in Biel, Switzerland
The centrepiece of the day was the clash between the two leaders. Carlsen snatched a pawn early on, but with his knight in some trouble on b7, and Black's pieces extremely active, it looked as though White had nothing. However, just when everyone thought the draw was inevitable, Carlsen produced the devilish trick, 29.b4!, and within two more moves, it was clear that Black was losing a piece to the lethal pin on the b-file.

Bu-Motylev was a very obscure game. The forcing sequence between moves 11-20 saw White emerge with an extra pawn, but the position became very messy as Black's pieces penetrated the enemy position. An attack of "wrong rook syndrome" at move 30 saw Black miss his last chance of salvation, however.

Polgar's 4.d3, avoiding the Berlin Wall, never brought any advantage in a typical quiet Spanish. Indeed, by move 25, it was even Black who had a small initiative, although a draw always looked far the most likely result.

Israeli grandmaster Boris Avruhk
Grischuk's simplifying 13...Ne4 forced an endgame where White retained some pressure. Van Wely looked to be making progress, but the advantage slipped away around moves 30-35, without it being entirely clear how else he should have played.

Finally, Pelletier-Radjabov was a short draw, with few features of interest.
