Muzychuk, 2nd Trophée Anatoly Karpov, Cap d’Agde 2013. 12. ... Rc8 13. Bd2 Qb6 14. Qxb6 axb6 15. Be1 Rfd8 16. e3 Be4 17. Ng5 Bxg2 18. Kxg2 h6 19. Nf3 Ne4 20. Rab1 cxd4 21. cxd4 Nc3 22. Bxc3 Rxc3 23.

Objectively speaking, Black has not sufficient compensation for the Exchange, and after the comparatively better 45. ... Kc6 (threatening to trap the Rook by ... Kc6-b7) 46. Ra8 Kb7 47. Rg8 a4 48. Ke2 a3 49. Kd3 f4 50. exf4 Bxf2 51. Kc2 White also wins in a similar manner to the text. 46. Ra8 a4 47. Ke2 e5 48. Kd3 e4+ 49. Kc2 f4 50. exf4 Bxf2 51. Re8 e3 52. f5 e2 53. Rxe2 Bd4 54. Re4 Kc4 55.
