1.1...Qf3!! and White resigned as there is no good way to avoid mate. 2.Qxf3 exf3 3.Nd5+ Bxd5 4.cxd5 Rxg2+ 5.Kf1 Rh1# is just one of many examples.

2.1...d4 2.Rxd4 Re1+ 3.Rd1 Rxd1+ 4.Qxd1 Qxc3+ 5.Kb1 Qxh3 with a winning queen ending.

3.1...cxd2 2.Rxc7+ (2.Qxd2 Bf1+ -+) Kxc7 3.Rxd3 Rxd3 4.Qc4+ Bc5!! (4...Kb8 5.Qxd3 Be3 6.Bc3 +-) 5.Qd3 (5.Qxc5+ Kd7 6.Bd4 Rc8 29.Qd6 Ke8 -+) Rd8 6.Bd4 Rxd4 and White resigned.

4.1...e2 2.Bxf2 (2.Ba5+ Kc6 3.Ra1 Be3 -+; 2.Rxf4 Rxf4 3.Bg3 Kc6 -+) Be3 winning

5.1...Nfxd4! wins material for Black, and removes White's key pawn that holds everything together. 2.Rac1 (2.Nexd4 Qxc5 leaves black up a pawn and an exchange) Nxf3+ 3.Qxf3 (3.gxf3 Nxe5 also leaves Black 2 pawns up) Nxe5 4.Rxc8+ (4.Qg3 Rxc5 gains Black even more material) Rxc8 5.Rxc8+ Kxc8 6.Qc3 Qc7 leaves Black 2 pawns up.

6.Black can force the queens off and win with 1...Rxe5 2.Qxe5 Qf5 3.Qc3 Rd1+ 4.Kh2 Qf4+ 5.Qg3 (5.g3 Qf2 is mate) Qxg3 6.Kxg3 Rd2.

7.1...exd4! 2.Bxf7+ (2.Rxe7 is answered by Qxe1+ follwed by mate) Kh8! and White resigned as there is no way to avoid mate without losing material.

8.1.Qb2 and White resigned as his rook is about to drop. If 2.Rc2, then 2...Qb1+ followed by 3...Qxc2. Note that 1...Qb1+?? fails to 2.Qf1 doesn't work because Black can't do 2...Rd1 due to 3.Rc8+ followed by mate.

9.1...Nxf2!! 2.Rxf2 (2.Qc2 dxc3 -+) dxc3 -+.

10.1...Nc2!! 2.Rf1 (2.Qxc2? Bxf2+ 3.Kxf2 Ng4+ 4.Kf3 Qf6+ 5.Kxg4 Rc4+ 6.bxc4 Bc8+ 7.Kh5 Qh6#) Nxa1 3.Qxa1 Rfd8 4.Bf3 Ba3 -+.
