19... Ne4
Spassky places his knight on the e4 outpost and attacks the pinned knight. Is he starting to get counterplay?

 
20. Qe2 Nxc3 21. Bxc3
He is not. The maneuver, Bf3-e5-c3, gives White a clear positional advantage.

21... Rd8
A forced defense.

 
22. Rd3
Karpov prepares to load his heavy pieces on the weak pawn.

 
22... Rcd6 23. Rfd1 Rd6d7 24. Rd1d2 Qb5 25. Qd1
The Alekhine's gun on the d-file has Black tied down to its defense, but Karpov will need to open a new front to win the game. The usual way to win a pawn, e3-e4, does not work at the moment because d7 is protected 4 times. But the passivity of Black's pieces will ensure that Karpov will have the advantage when he finds a new plan.

 
25... b6 26. g3
Do not hurry when your opponent is tied down.

 
26... Bf8 27. Bg2 Be7 28. Qh5
White's queen reaches an active square, and e4 is threatened.

 
28... a6 29. h3 Qc6 30. Kh2
These 'quiet' moves are a key part of Karpov's play.

30... a5 31. f4
With the threat of f5 winning the bishop.

 
31... f6 32. Qd1 Qb5 33. g4
Karpov will force the e6-bishop away from guarding the d7-rook. Note that because Black's pieces are in a bind, there are no problems with pushing the pawns in front of the king.

 
33... g5 34. Kh1 Qc6 35. f5
Now the bishop will not control d7.

 
35... Bf7 36. e4 Kg7 37. exd5 Qc7
Now Karpov prepares the end of the game.

 
38. Re2 b5 39. Rxe7
The winning tactic.

 
39... Rxe7 40. d6
Forking the queen and rook.

 
40... Qc4
The d pawn is pinned, but there is a move that forces resignation.

 
41. b3
The black queen is deflected from d3. If 41...Qxb3??, then 42. Bxf6+, so black resigns.
