Ceskoslovensky Sach – 2014
1.Nf6! Sacrifices the knight due to stalemate and simultaneously overlays the important sixth row, as in Matous. And it’s not like overlay column g?
1.Ng5?! Bxg5 2.Bf5 Kc8! (2…g1Q?! 3.Rb7+ Ka8 4.Be4= with same draw) 3.Rd2+ Kc7 4.Rd7+ Kc6 5.Be4+ Kxd7 6.Bxg2 Be3 7.Kb5 Kd6 8.Kc4 Ke5 9.Kd3 Kf4 10.a6 Kg3 11.Bc6 Kf2–+
1.Nf8? g1Q 2.Rb7+ Kc8 3.Bf5+ Kd8 4.Ne6+ Ke8 5.Be4 h1Q-+
1…Bxf6 2.Bf5 g1Q
2…Kc8 3.Rd2+ Kc7 4.Rd7+ Kc6 5.Be4+ Kxd7 6.Bxg2= compare variant with black bishop on g5, when black wins 6…Bd4 7.Kb5 Kd6 8.Kc4 Ke5 Here a black bishop is attacked (in variant 1. Ng5? stands in this position black bishop on e3) and white has time for move 9.a6!=
3.Rb7+ Ka8 4.Be4! followed by fireworks stalemats 4…h1Q
main 4…h1B 5.Bc6! Bxc6 (5…Qf1+ 6.Rb5+ Bxc6 pat) 6.Rb8+ Kxb8 stalemate
5…Qf1+ 6.Rb5+ Qxd5 stalemate
6.Rb8+ Kxb8 stalemate
This works perfectly summarizes long research of old study of Matous , which appeared incorrect and also the possibility to combine effective stalemates with new subtleties in the endgame unequal bishops.
