now game in forced way is switched into known pawn end, 16.Bxf6 [Tatjana did not like her last handling of Dragon 16.Nd5 Nxd5 17.Bxg7 Kxg7 18.exd5 Rc7 19.h4 Rac8 20.a4 Qb6 21.Re2 h5 22.Qd3 a5 23.g4 Rh8 24.g5 Qb7 25.Rde1 Re8 26.Re4 Rc5 27.Rd4 Qd7 White had more opawn weaknesses,but was able to save the game later, Kosintseva,T (2532)-Cmilyte,V (2508)/Kazan 2012] 16...bxc3 17.Bxc3 Bxc3 18.bxc3 Rxc3 19.Re3 Rac8 20.Rxc3 Qxc3 [Black would really suffer in the Rook endgame after 20...Rxc3 21.Kb2 Rc5 22.Qxa5 Rxa5 23.Rc1] 21.Qxc3 Rxc3 22.Rc1 Rxc1+ 23.Kxc1 Kf8


This pawn end was extensively and I would say ultimately analysed by IGM Karel Van Der Weide & IM Jeroen Bosch few years ago in New in Chess in brilliant article.I remember conclusion ,that Black achieves draw after very bad suffering,if I am not mistaken.

28...f6? Viktoria believed that it is the decisive mistake and possibly best way to draw was [28...h5] 29.a4 e6 30.g4 g5 31.hxg5 fxg5 32.b5+ axb5+ 33.axb5+ Kc7 34.Kb4 Kb6 35.Ka4 h6 [Black cannot play 35...d5 36.exd5 exd5 37.Kb4 h6 38.Ka4 d4 39.Kb4 d3 40.Kc3 Kxb5 41.Kxd3 Kb4 (41...Kc5 42.Ke4) 42.Ke4 Kc3 43.Kf5 Kd3 44.Kg6 Ke3 45.Kxh6 Kxf3 46.Kxg5] 36.Kb4 Kc7 37.Ka5 Kb7 38.b6 Ka8
