1…Nd6+
1…Bf4 2.Ke8 Bb8 3.Kd7 Nd6 4.Nc5+-
1…Be1 2.Ke7+-
1…Bb4 2.Ke8! Nd6+ 3.Kd7 Nxb7 is as main line

2.Ke7 Bb4 Moving the bishop from an attack and preparing for the capture of b7 pawn
2…Nxb7 3.Nxd2 Na5 4.c7+-

3.Kd7! Nxb7 4.Na3!! First sacrifice on a3 (which black can’t accept)
4.c7 Nd6= with Ba5 threat

4…Nd6
4…Bxa3 5.c7 Nd6 6.Nd4! Kb7 7.Nb5! Nc8 8.Nxa3 Nb6+ 9.Kd8+-

6…Nxb5 7.Nxb5 Ba5 8.Kc8 Bb4 9.Na3!! Again – kni ght sacrifice on the same square. This time unexpected move with the knight backward. Looks strange, but I didn’t find any study in this basic position. This is the only winning move. Other moves will only waste time and White needs to return to this position
