Radjabov surprised the spectators by agreeing a micro-draw with Motylev. Why would the co-leader waste his final White in such fashion? I guess they call it "tournament tactics"...

However, Radjabov's decision looked a good deal more sensible a few hours later, when Carlsen slumped to his second straight defeat. He was in trouble very early on against the hitherto winless Van Wely, and the upshot of the Dutchman's piece sacrifice was an ending where White had a veritable rain-forest of passed pawns on the kingside. Carlsen struggled on to the death, but there was no stopping the pawns.

Onischuk jumped into a share of the lead, by beating Avrukh. White achieved only a small edge against the Grunfeld, but the critical moment came at move 21. The Israeli GM traded his Grunfeld bishop, in order to snatch a pawn, but after the fine zwischenzug 27.Qxe7!, his king proved fatally exposed. He staved off mate by surrendering a pawn, but succumbed in the minor piece ending.

"Nothing succeeds like success", the saying goes. Yannick Pelletier proved the truth of this, by following up yesterday's win over Carlsen with a fine and thematic crush of Bu Xiangzhi's Slav. Black's Achilles' Heel in this variation is often the bishop on g6, which can be shut out by the white pawn on e4. Pelletier carried out the plan to perfection.

Polgar had a remarkable escape at the hands of Grischuk. Her Petroff Defence went horribly wrong inside 15 moves, and she was soon defending a technically lost ending. Tenacious defence could not prevent Grischuk reaching an ending of N+2Ps v N, which should have been an elementary win. However, just when the online spectators were wondering why Polgar was still playing on, she produced the fiendish resource 61...Ng4!!, and despite lengthy thought, Grischuk could not find a win.
