17. Qg4 Nf4 18. Rfe1 Rg8 19. Qf3 Rd8 20. Be4?! A novelty of dubious value instead of 20. Rad1 c5 21. Be4 Bxe5 22. dxe5 Rxd1 23. Rxd1 Bxe4 24. Qxe4 Ke7 25. h4 Rd8 26.

Bf2 ½ : ½ Anand – Wojtaszek, 33rd German Schach Bundesliga, Baden-Baden 2007. 20. ... f5! 21. Bxc6 Bxe5? Strong and consistent was 21. ... Bxc6! 22. Nxc6 g4 23. Qc3 Rc8 with a quasi-winning game. 22. Bxb7 g4?? (22. ... Bxd4!⩱) 23. Qc6 Qxc6 24. Bxc6 Bxd4?! After 24. ... Bf6 25. c3 White has the Bishop pair and an extra Pawn — not a good deal for Black, but the text move is a much worse one. 25.

51. Bg3? This was maybe 侯逸凡 (Hóu Yìfán)’s only slip in an otherwise well played ending. 51. b4 Rb3 (51. ... b5 52. Be6!+−) 52. Bd6 should win for White. 51. ... b5!= 52. Kf3 bxc4 53. bxc4
53. ... Kc5? All’s well that ends well. 53. ... Kd3, 53. ... Rh5, 53. ... Rh7 or 53. ... Rh8 are tablebases draws. 54. Kf4+− Kb4 55. Be1+
