1. 1… Qxf5 2 gxf5 Rxe5! Wins a piece, but not here 2… Nxe5? When 3 Kf4 regains the piece. 2. White wins material by 1 Rxd4 since capturing the Rook by Pawn or Rook allows 2 Re5+ Kxg4 3 f3 mate. 3. 1… Nf3+ 2 gxf3 Bxc3+ 3 bxc3 Qxb5 winning the Queen. Note that Black can avoid the loss of his Queen by 2 Kf2 but then 2… Qxb5 3 Nxb5 Nxh4 leaves him a piece down in the ending. 4. The Bishop on f1 must be eliminated, so 1… Rxf1+ 2 Kxf1 Qxg2+ 3 Ke1 Nd3 mate. 5. 1… Bb1+ 2 Kxb1 Rxb3 wins the exchange. 6. 1… Nd4 wins White’s Queen, because 2 Nxd4 allows 2… Qxh2 mate and 2 Qd3 allows 2… Nxf3 Qxh2 mate. 7. Since Black’s Rook is preventing the advance of the Pawn, 1 Rg2+ Rxg2 2 h8=Q leaves White with Queen against Rook. 8. White’s Queen is pinned. However 1Rf3+ Kg8 2 Rf8+ not only unpins the Queen, but forces 2… Rxf8 3 Qg7 mate. 9. The Knight on d3 cannot guard both Bishop and Rook, so simply 1… Rxe1+ 2 Nxe1 Bxc5 wins a piece. This cannot be done in reverse order since after 1… Bxc5 the intermediate move 2 Rxe8+ saves the piece. 10. White exploits the fact that lack’s Queen must guard the Rook by playing 1 Nf6+ Kh8 2 Ne8 when White threatens both the Rook andmate on g7. Black is forced to give up the exchange by 2… Qxe8 3 Qxc7. 11. Black’s Rook cannot guard both the Queen and the back rank, so 1 Re8+ Rxe8 2 Qxd5 wins the Queen. 12. On its own, the Bishop cannot stop both the Pawns, which means that Black’s King has to stop the g-pawn. However, the King is overloaded, because it also has to guard the Bishop. This gives us 1 g6 Kf6 2 g7 Kxg7 3 Kxe5 and the b-pawn promotes.
