Now White is able to exploit the first motif, the lack of protection of the c2-rook, with a double attack:
23.Qd3!
Attacking the rook and the h 7-pawn, while keeping an eye on the e2-square. 23.Qf5, which was played in the game, is slightly less accurate.
At this point Black resigned, though there was still a defensive try in 23…Re2!. We will understand the importance of this defence later: 24.Qxh7 Bf6 and now:
A) 25.Rg8+ Ke7 26.Ng6+ Kd6.
Here the win is achieved thanks to another motif, the forking distance between queen and rook: 27.Rxd8+ (27.Nf4 Qe4 28.Qxf7 Rxg8 29.Qxf6+ Kc7 30.Qf7+ Kc6 is not so clear, even after 31.d5+ Kb6 32.d6) 27…Bxd8 28.Nf4 Qe4 29.Qh6+ Kd7 30.Nxe2 Qxe2 31.Qxa6 Qxb2 32.Re1+− and the rook and three pawns are much stronger than the bishop and knight;
B) 25.Rc1!. This cool computer move, intending to penetrate via c7, is the strongest. Black has no defence. 25…Nc4 is the obvious try, trying to block the c-file while centralizing the awkward a5-knight. Nevertheless, the combination of these two moves is in Whites favour, in one variation only.. Here a computerish solution is available, thanks to a kind of domination/ deflection of the black queen: 26.Rg8+! Ke7 27.Ng6+ Kd6 28.Nf4!. Now f7 cannot be protected. Of course, this is very difficult to spot from a human point of view, which is why I prefer the more logical main variation (line A).
28…Qe4 29.Qxf7 and now:
B1) 29…Re1+ 30.Rxe1 Qxe1+ 31.Kh2 Rxg8 32.Qxf6+ Kd7 33.Qf7+ Qe7 34.Qxg8 and wins;
B2) Here is the variation in question: 29…Rxg8 30.Qxf6+ Kc7 31.Qf7+ Kc6 (31…Kb6 is worse: 32.Nd5+ Kc6 33.Qc7+ Kxd5
34.Qd7+ Nd6 35.Rc5+ Kxd4 36.Qxd6+ Qd5 37.Qxd5#) 32.Qxg8 Qxf4
33.Rxc4++−.
23…Rcc8
The best possible defence is 23…Re2, but even here, the concrete 24.Qxe2 is overwhelming.
24.Qxh7 Bf6
Now the e-file is available, so:
25.Re1!
1-0

Solution 4 (page 174)
Here the best move is a quiet one.
1…Qc5!
A famous, but wrong combination starts with 1…Rxh2!? (who could resist the temptation?) 2.Rxh2 Qxa3 3.bxa3 Bxa3+4.Kb1 Nc3+5.Ka1
5…Bb2+ 6.Kxb2 Nxd1+. The combination usually stops here. You get one consolation point if you spotted this sequence, but 2 points if you played 1…Qc5. Nunn, in his puzzle book, claimed that the position is not clear after 7.Ka2 Nxe3 8.fxg5 and White should hold the draw with best play.
2.Qxc5 Bxc5 3.Bxe4□
3.fxg5 Be3+4.Kb1 Nf2−+.
3…Be3+ 4.Kb1 Rxd1+ 5.Rxd1 fxe4 6.Bg1 Bxg1 7.Rxg1 gxf4−+
Back
Solution 5 (page 174)
The situation looks awkward for White: The c5-rook could easily be trapped, the a3-bishop is unprotected, and his king is still in the centre, which means that Black will have a check available.
Nevertheless, there is no forced win here (at least according to my 2012 computer, assisted by Houdini 1.5), partly because Black also needs a developing move, like castling, in order to have everything in order. Still, as the rest of the game shows, White has a long-term problem with his advanced rook, which he was not able to solve in the game.
13…Qd7 14.Qb3 0-0 15.hxg6 hxg6 16.Bc4
16.Be2∞.
16…Bf6 17.d4 b5 18.Bd5 Na5 19.Qd1 Nb7 20.Ne5 Bxe5 21.dxe5 Nxc5 22.Qd4 Nd3+ 23.Kf1 Qa7 24.Bxe7 Qxd4 25.cxd4 Nf4
0-1
Mark one point if you have spotted that there was no combination, and one more point if you decided to play a quiet move, like Karpov.

Solution 6 (page 174)
28.Qh4!
This wins by force, at least threatening Rxg6+ followed by Rh8+ and Rh7+, winning the queen. The right motif here is that the defence (i.e. Black’s other pieces) is too far away, and the relevant theme is elimination of the defender (i.e. the knight on g6).
28.Nxd6 was the game continuation, which led to an unclear position (according to the same computer!): 28…Rxa2 29.Be4 f5 30.Nxf5 Bxf5 31.Bxf5 Qxe2 32.Rxg6+ hxg6 33.Rh8+ Kg7 34.Qh6+ Kf6 35.Rxf8+ Ke7 36.Qg7+ Kd6 37.Rf6+ Kc5 38.Qc7+ Kd4 39.Qf4+ Kc5 40.Qc7+ Kd4 41.Qf4+ Kc3 42.Qg3+ Kd4 43.Bh3 Rd2 44.d6 Qe3+ 45.Qxe3+ Kxe3 46.d7 b5 47.Rf8 b3 48.Re8+ Kf3 49.d8Q.
28…Qg7
The only defensive try. But now White has the devastating
29.Rxh7! Qxh7 30.Nxf6+ Rxf6 31.Qxf6+− Bf5 32.Qxf5 Kg7 33.Be4+−
1-0

White wants to get rid of the annoying rook on c2, and tries to use the fact that the g7-bishop has the duty of protecting against the checkmate on g7. So he deliberately puts the knight en prise:
