25.1.Rxf7!! Nxf7 2.Rxf7 Kxf7 (2...Bd8 3.Ra7! Qxa7 4.Ne7+ followed by 5.Ng6#) 3.Nb6+ Kg6 (3...Kf8 4.Nd7#; 3...Kf6 4.Nd7+! Kg6 5.Bh5+ leads to a position similar to the one reached via 3...Kg6) 4.Bh5+! Kxh5 5.Qf7+ and Black Resigned as 5...Kg4 6.h3+ Kh4 7.Qf4+ Kh5 8.Qg4# and 5...Kh4 6.g3+ Kh3 (6...Kg4 7.Qf5#) 7.Qh5+ Bh4 8.Qxh4# both lead to mate.

26.1.Nxd5! exd5 (Here, White will win because Black has moved his a-pawn already, whereas White hasn't, and therefore can move the pawn either 1 or 2 squares) 2.Kb4 Kd7 3.Kc3 and now both 3...Kc6 4.Kd4 a5 5.a4 and 3...Kc7 4.Kd4 Kc6 5.a3 a5 6.a4 lead to reciprocal zugzwang with Black to move, therefore Black Resigned.

27.1.Rxd4! Rf7 (1...exd4 2.Be2! +-) 2.Qh8+ Rf8 3.Qh5+ and Black Resigned.

28.1.Bxh7+! (A classic example of the Greek Gift Sacrifice) 1...Kxh7 2.Ng5+ Kg6 (Forced!! 2...Kg8 3.Qh5 and mate can't be avoided) 3.Qg4 f5 (Common, thematic move in the Greek Gift) 4.Qg3 Qc8 5.Rc3 f4 6.Qg4 Nf5 7.Rh3 (Preventing Black from escaping via Kg6-h7-g8 when the White knight moves) Rh8 8.Ne6+ Kf7 9.Qxf5+ Ke7 10.Qg5+ Kxe6 11.Qg6+ Ke7 12.Qxg7+ and Black's about to lose his rook because 12...Ke6 13.Qf6 is mate.

29.1.Bxc4! wins a pawn for White as 1...dxc4? 2.Nxc4 Qc7 3.Nd6+ Kd8 4.Nf7+ wins White a rook. 1...Qc7, giving up the pawn, is necessary.

30.1.Rxf7+! Kg8 (1...Kxf7 2.Re7+ Qxe7 3.Qxe7+ winning; 1...Ke8 2.Rexe7+ winning) 2.Rxg7+ Kf8 3.Rexe7 and Black will be mated soon.

31.1.Rh8+!! Kxh8 2.Bxe5+ Qxe5 3.Qxd8+ Kg8 4.fxe4 and White has a won endgame.
