  Penguincw: According to chess24, 54...Qxf2+ was a blunder by Mamedyarov, but Grischuk returned the favour with 58.Bb2.

One possible finish: 64.Kc1 Ka2 65.Bd4 b2+ 65.Bxb2 d2+ 66.Kc2 d1=Q+ 67.Kxd1 Kxb2, and the c-pawn should promote.

Tough stretch for Grischuk here, as he has now dropped back to back games, although he might have fared better if he was better at time management...

Meanwhile, Mamedyarov improves to 3/4 with black, while remains 0.5/3 with white. :|

  HeMateMe: why does white allow 10...Qx-a2, losing a pawn? Is this to avoid exchanging queens early in the game? It seems that white got nothing out of this opening, was down two pawns most of the game and had zero counter play, except for desperation queen checks at the end.

  luzhin: Actually White was doing well before the appalling 17.Ra5?? clearly missing the force of 17...Qh6! After 17.dxe5 the two Bishops in such an open position are certainly worth the pawn.
Feb-22-15  Nf8: What a waste of great home prep by Grischuk with his 17th move - of which he thought for more than 40 minutes.

<According to chess24, 54...Qxf2+ was a blunder by Mamedyarov, but Grischuk returned the favour with 58.Bb2> It's according to the computer evals in their live broadcast (https://chess24.com/en/watch/live-t...), but neither of these moves is really a blunder - probably lack of sufficient ply-depth in the analysis. The comp's first choice is the elegant 54...d2, but the bishop endgame after the queen exchange is completely winning as well - White can't avoid an eventual zugzwang as the one he gets into on move 63.
