An upset win for White over USA's Olympiad top board. White gets into trouble early after opting to long castle against the Petroff, facing a furious queenside pawn storm. Black missed one resource to keep the pressure on, and afterwards her attack was slowed to the point where, even when she won material, it was too late. In the ensuing queen endgame, Black faced serious problems and was unable to solve White's king activity. } 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. Nc3 Nxc3 6. dxc3 Be7 7. Bf4 Nd7 8. Qd2 Nf6 9.
