侯逸凡 (Hóu Yìfán) – Radoslaw Wojtaszek
Biel/Bienne, July 21, 2014
5rk1/5ppp/1rNq1b2/1P1b4/Q2PB3/4R1P1/2p2P1P/4R1K1 w - - 2 29


Hóu Yìfán had an excellent chance to take over solo second, but spoiled a winning position against Wojtaszek. Her 29. Qxc2 was very natural, eliminating a dangerous passed Pawn and consolidating her material advantage, but after a long series of exchanges her winning chances were minimal. Instead 29. Bxd5 Qxd5 30. Re8 (threatening 31. Qa4-a3!/Qa3-b4!) would have won. After 30. ... g5 (30. ... g6 31. Qa3! mates) 31. R8e5! (not 31. Qa3 this time, because after 31. ... Rxe8 32. Rxe8+ Kg7 33. Qf8 isn’t mate; here Black is even winning) 31. ... Qf3 (not 31. ... Bxe5?? 32. Ne7+) 32. Rc5 and now White will be two Pawns up, not just one, and will win.
