It found Kxh7 in just a few seconds and won the game without problem, but.. Looking into the position more deeply, letting the engines work with more time, I have reached the following position in which I´m not sure if white wins so easy. This is the principal line I have followed : 17... g6 18. Nxh7 Qh6 19. Nxf8 Bxf8 20. Bc1 Qh5 21. Rde1 Bg7 22. Qg3 c5 23. Re7 cxd4 * [D] r1b3k1/3nRpb1/p4np1/3p3q/NpPp4/1P1B2Q1/P6P/1KB3R1 w - - 0 24 Now I believe Bg5 is the move, but I don´t know if the advantage is enough. Regards, Fernando.
