Very clear description, Gustavo. Now for the chess part, since in my opinion it's an interesting problem. That's the winning line: Troitzky,A 1.h6! gxh6 2.e7 Rb1+ 3.Kd2 Rb2+ 4.Kd3 Rb3+ 5.Kd4 Rb4+ 6.Kd5 Rxb5+ 7.Kxd6 Rb6+ 8.Kd5 [8.Kd7? Rb1] 8...Rb5+ 9.Kd4 Rb4+ 10.Kd3 Rb3+ 11.Ke2 Rb2+ 12.Kf3 Rb3+ 13.Kf4 Rb4+ 14.Kf5 Rb5+ 15.Kf6 Rb6+ 16.Kf7 1-0 It takes a very deep search to find 1.h6. Enrique
