Karpov likes this method of dealing with the English. One line for White now continues 4PxPNxP5 P-KN3, but Smyslov decides on a Queen's Gambit Declined type of position with an isolated QP.

4 P xP NxP

10 R-Kl N-B3 Smyslov suggests 10 ... B-B3 as an alternative in his notes to this game in Informator.

The text move is played to avoid the difficulties arising after 10 . . . P-QN3 11 B-K4!, but it involves a clear loss of time for Black and White's next move gives him the edge.

10 . . . NxN, as pointed out by Yudovich, is also possible.

This prevents the manoeuvre . . . N-QN5-Q4 and prepares to line up the queen and bishop against the black king. Now Black will have trouble blockading the QP.

He should have played 13 ... P-N3. Now the isolated pawn gets its chance for a glorious death. . ..

But Smyslov misses it! He should have played 14 P-Q5!:

(a) 14 ... PxP 15 B-N5 P-N3 16 RxB QxR 17 NxP NxN 18 BxQ N3xB with a substantial material plus for WTiite;

(b) 14 . . . N-QR4 15 B-N5 R xN (15 . . . P-N3 16 P-Q6!±±) 16 PxR QxP±.

15 QR-Q1

White still has much the better game, and it is hard for Black to find a move which does not allow his opponent to improve his position.

Preparing to drive away the bishop with . . . P-QN4, but this move falls in with White's idea.

'On 17 ... NxN White had the choice between the solid 18 Q x N or a promising pawn sacrifice with 18 P XN B x P 19 P-B4, having in mind a later P-Q5. The text leads to difficulties of another kind.' - Keres.

Korchnoi gives 17 . . . NxN 18 PxN BxP 19 P-B4 B-Bl 20 Q-K3± or20B-KN5±.

'It is understandable that Black does not want to remain in a slightly inferior position after 18 . . . PxN, but that may have been the lesser evil. Now he has to be alert to the possibility of a breakthrough with P-Q5, which finally brings the decision.' - Keres.

Now the point of White's seventeenth move is shown; without the interposition of 17 B-R4 P-R3, Black could meet the threat of 20

B-N3 with 19 ... N-R4! White's last move covers the QB so that 20 B-N3 Q-KR4 21 P-Q5! is possible.

'This leads by force to material loss, but Black's position is already difficult. After 19 . . . Q-KR4 the continuation 20 P-Q5! PxP 21 QXP is very strong, but 19 ... R/ Kl-Ql was probably his best practical chance. Now Smyslov finishes the game with a few strong blows.' - Keres.

'This Sword of Damocles has been hanging over Black's head for some time, and now it falls with decisive effect. Even Tarrasch mentioned that isolated central pawns can sometimes change from weaknesses into formidable striking forces!' - Keres.

BxN, as 23 P-Q7! would then cost him a whole rook. But with 22 . . . R-Rl, Black could probably put up tougher resistance, protecting his first rank.' - Keres.

The decisive mistake. He can hold out a little longer by 23 . . . R-KB1 24 B x R K x B, but it hardly matters any more. Korchnoi recommended 23 . . . R-KB1 (23 . . . R68 sic) as better.

'A move of terrible strength. The double threat 25 QxB and 25 Q-N8 cannot be stopped simultaneously!' - Keres.

25 Q-N8 QxB

26QxN+ B-KB1

27R-K3!

A rather cruel touch; Smyslov sees no reason to allow his pawns to be broken up (as they would be after the immediate 27 QxB+, which also wins), since his next move cannot be prevented.
