Deac - So: 0.5-0.5

Lupulescu - Mamedyarov: 0-1

Lupulescu was playing fine till Mamedyarov made a strong breakthrough.

Position after 33.Bf1

Black went for the obvious 33...e5 break. White could have tried to hold a bit longer 34.Nh4 exf4 35.exf4 or even 34.Rb2 was fine. 34.fxe5 spelled doom for white as after 34...Rg6 white has no way to defend the g3-pawn and the kingside gets completely annihilated. Thus Mamedyarov scored his first victory of the event.
