| If 1.b3 then 1... Kxc8 draws, so White needs a more urgent move... | |
| 1.Nb6+ | Kc6! |
| The best defence. If 1... Nxb6 2.Bxb6 h4 3.Kg6 h3 4.Bg1 Kc6 5.Kg5 Kb5 6.Kg4 Kb4 7.Kxh3 Kb3 8.Bd4 | |
| 2.Nxa4 | Kb5 |
| Now White must lose a piece | |
| 3.Bc3! | Kxa4 |
| 4.Ke6! | h4 |
| 5.Kd5 | h3 |
| Otherwise the White king can catch the pawn | |
| 6.Kc4! | h2 |
| 7.Bb4 | h1=Q |
| 8.b3# | |
