Be3 Nxe4 (30. ... Qg6!?) 31. Rc6 Ra8!

32. Qa4. White forces simplification in search of a laborious balance. More interesting may be 32. Rb6 Qf5 with approximate dynamic equality, Blomqvist – Brynell, 29th Politiken Cup, Copenhagen 2007. 32. ... d2! 33. Nxd2 Nxd2 34. Rxa6 Qxb2 35. Bxd2 Rxa6 36. Qxa6 Qxd2 37. Qc4 Qd1+!?

52. Ne4? It is likely that due to the proximity to the goal 侯逸凡 (Hóu Yìfán) fell into an incorrect assumptions about the inevitability of a draw. 52.
