The one that I posted yesterday Chess tactics #5: Yugra Governor's cup wasn't the only blunder that happened yesterday in this tournament. In the game between Alexey Sarana (2426) and GM Pavel Ponkratov (2604) the following position was reached:
[fen "5rk1/1bn1q1bp/p2p4/2pP1P2/1rB5/2NQ2BP/RP3PK1/5R2 w - - 0 1"]
White has just played 25. exf5. How did Ponkratov win the game?
