BxN 13 PxB BxN 14PxBN-K4 15 Q-B4 with an unclear position, and probably rather better chances for White. 9 . . .

36 . . . P-N4? Black had to play 36 . . . R-QN4. Now his rook is in trouble. 37 P-QB4 P-B4 And now 37 ... P x P would prevent matters getting too much worse. 38 K-N2 P-B3 39 P-B3 P xP 40 PxP B-B5 41 R-K4 1-0

20 N x N 20 N-B7 + RxN21 BxQ B X B is unclear, but probably Black's three pieces would be better than the queen. 20 ...

Black has a constricted position with a weakness at d6 which, as the game shows, is of more consequence than White's at d5.14 B-B4 N-B315 0-B2 N-Q4 16 B-06! Now if Black elects to trade his dark square bishop for this unwelcome guest, a white knight will soon take up residence with even more unpleasant consequences. 16 • •. P-B3 17 P-QR3 Q-02 18 N-02! Going ahead with his knight manoeuvre, for if 18 . . . BxN White is left master of the dark squares. 18 . . . B-Ql 19 R-Kl P-QR4 20 B-R3! Q KB2 21 Q. K4 B B1 22 P-B4 Black is now getting slowly strangled - a little more preliminary work and there comes a breakthrough. 22 . . .

30 B-R3 R-KN1 31 B-N2 QR-K1 32 R-KB1 K-R2 33 P-KN4! This pawn advance, in conjunction with the further weakness created on move 29 is sufficient to give Karpov decisive threats. 33 ... B-Ql 34 Q-

B x B 36 P X B Q-Bl 37 Q-R4 P-R4 38 P x P followed by a knight entry at e5 leaves Black's position in a state of disarray. 36 P X BP B x P 37 N-K5 Q N2 38 R2-KB2! Doubling rooks on a closed file which will later be opened. 38 . . . B-Bl 39 Q-R3 B x N Though this exchange allows the white rooks to penetrate, it was forced sooner or later owing to the threat of piling up on g6 with B-K4 and R-KN1. 40 BPxB QrRl To save the lady. 41 R-B7+ R-N2 42 B-B8! 1-0 A picturesque finale: after 42 . . . RxR 43 Q xRP+ K-N1 44 QxP+ R-KN2 45 BxR QxB 46 QxR+ K-R2 47 R-B7 and Black loses all his pieces.
