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.Bd5! Qxd5
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.
