The prodigy-2

I understand that the rumoured Fischer v Botwinnik match will definitely take place in Holland next spring and that the conditions have been accepted by both players. it will be an eighteen game match, lasting six weeks. If Botwinnik gets off to an early lead, I think that he will win; but if Fischer holds his own in the early part, then age will probably tell and he should win. In any case it should be a fascinating match; I hope that it succeeds in starting—and finishing.

The following game is taken from Fischer's My Sixty Memorable Gaines reviewed in this column last week: notes based on those in the book.

White, Letelier (Chile). Black, Fischer (US). (Olympiad, Leipzig 1960). Opening, King's Indian Defence.

P-Q4 Kt-KB3 2 P-QB4 P-KKt3 3 Kt-Q133 B-Kt2 4 P-K4 0-0

5 P-K 59 Premature: this appears to gain

tinw, but much more is lost in defending the advanced pawns.

5 Kt-K1 6 P-B4 P-Q3

7 B-K3 . Better 7 Kt-B3,PxP; 8 QPxP!.

The delay in developing his king's side costs White dear.

P-01141 8 P x BP Kt-QB31

, 9 BP x P . . Too dangerous. Kt-B3 is correct.

9 .... P xP 10 Kt-K4"

Very weak; he must develop by Kt-B3.

10 .... B-B4 II Kt-Kt3? . .

Fischer gives as best 11 Kt xP, Kr x Kt; 12 QxKt, QxQ; 13 PxQ, BxP; 14 R-Q1, 110-Kt5 I; 15 K-B2, Kt xP and White 'may have drawing resources'.

11 .... B- K3 12 Kt-B3 Q-B2

13 Q-Ktl .... Still hoping to get an attack going with the remnant of his pawns; there is, however, no satisfactory move.

13' .... P P 14 P-KB5 P-K51

15 P x B 15 QxP, P1; 16 Kt xP?,

Q-R4ch! or 16 Q-R4, B X Kt?.

15 PxKt 16 KtPxP P-B41 17 P-B4 Kt-133 18 B-K2 K R-K I

19 K-B2 .... 19 0-0, RxP; 20 13B2, Kt-K5;

21 Kt x Kt, R x Kt followed by RxKBP.

19 • • • • R t P 20 R-K1 QR-KI 21 B-B3 Rx131 22 RxR RxR 23 K x R Q f Pch ! 'This must have been a horrible shock. If 24 K x Q? then 24 . . . B-R3 mate or 23 K-B2, Kt-Kt5ch; 24 K-Kt2, Kt-K6ch; 25 K-B2, Kt-Q5; 26 Q-R1. Kt-105ch; 27 K-BI, Kt x B winning very quickly. So . . . .
