Turning The Tables
A player must be ever alert since chess offers sudden reversals of fortune. Here are two games from the 1972 USA championship illustrating this doctrine of the second chance. In the first I was ready to resign but got a gift; in the next my opponent was ready to resign but refused my gift.

King's Indian Defense
White: FEUERSTEIN 1 N-KB3 2 P-KN3 3 P-Q4 4 B-N2 5 0-0 6 P-B4 7 P-Q5 8 KN-Q2 9 P-QR3 10 P-QN4 11 R-R2 12 B-N2 13 RxB 14 PxP 15 N-QB3 16 RxP 17 Q-B2 18 KR-N1 19 N-B3 20 P-R4 21 N-Q4 22 N-B6 23 P-B4(b) 24 PxN 25 RxB 26 N-Q5?(c) 27 P-B7(d) 28 NxR 29 K-R2 30 Q-R4 31 P-K4 32 R-N5 33 Q-N4	Black: EVANS N-KB3 P-KN3 B-N2 0-0 P-Q3 N-B3 N-QR4 P-B4 P-N3 N-Q2 N-N2 BxB PxP PQR4 PxP QN-B4(a) B-R3 Q-B2 BR-B1 N-N2 BxP!? N-K4 NxN N-R4 NxR Q-R2 RxP QxN Q-B4 P-Q4 PxP Q-B3 R-R1 Resigns
(a) Correct is 16 … N-R4! followed by … B-R3. (b) Simpler is 23 RxB, NxR 24 N-N5, Q-Q2 25 QxN, etc. (c) 26 N-N5! wins outright. (d) Now he sees 27 QxN? P-QN4ch! winning the Queen. But 27 NxPch, QxN 28 QxN offers drawing chances.

Sicilian Defense
White: EVANS 1 P-K4 2 P-KB4 3 N-KB3 4 P-KN3 5 B-N2 6 0-0 7 P-Q3 8 N-B3 9 B-K3 10 P-Q4 11 R-K1 12 BPxP 13 NxP 14 QxN 15 Q-R4 16 QR-Q1 17 Q-N3 18 P-QR4 19 PxP 20 K-R1 21 QxNP 22 Q-R3 23 Q-N3 24 B-N6! 25 B-B1 26 B-Q4 27 Q-R2 28 BxB 29 N-Q5 30 QxB 31 P-B3 32 Q-B4 33 QxQ 34 R-K3 35 P-QN4 36 P-R4 37 R-Q5 38 B-R3 39 R/3-Q3 40 RxP 41 R-QB5 42 B-B1 43 R-K3 44 R-QR5 45 R-Q5 46 P-B4 47 P-N5 48 R-KB3(b) 49 R-Q8ch 50 R-Q7 51 R/3xP 52 K-N1 53 R-N7ch 54 R/Q-B7ch 55 R-R7 56 KxN 57 K-K1(d) 58 RxRP 59 R/R-N7ch 60 R/N-Q7	Black: LOMBARDY P-QB4 N-QB3 P-Q3 P-KN3 B-N2 P-K3 KN-K2 0-0 P-N3(a) B-QR3 P-K4 PxQP NxN1 BxP B-QN2 P-QR3 P-QN4 B-QB3 PxP P-N5 R-N1 R-R1 Q-R4 Q-R3 Q-B1 R-N1 N-B4 PxB BxN N-Q5 R-Q1 N-B6 KRxQ N-N4 R-B2 N-K3 R-R1 R-R7 N-Q5 N-K7 R/2-R2 N-B8 R-QB7 R-Q2 R-R2 R/2-R7 R/R-N7 N-K7 K-N2 K-N1 NxPch NxB(c) K-B1 K-K1 R-N7ch R/QN-B7ch K-B1 K-N1 K-R1 Resigns
(a) Stronger is 9 … N-Q5. (b) The win is 48 P-B5! N-N6 49 P-B6, R-B8 50 K-N1, N-Q7 51 R-K2! RxBch 52 K-N2, R-Q8 53 P-B7. (c) 52 … R-KR7! forces a draw. (d) Now White wins. Black, with split seconds left, checked with the wrong Rook. 56 … R/KN-B7ch would have drawn by perpetual check, preventing the King from escaping to QR1.

PROBLEM SOLUTION: 1 Q-Q2! threatening 2 K-N3. If 1 … BxN 2 Q-Q8. If 1 … KxN 2 Q-QR2

Stockfish Analysis.

21st USA Championship
14 top players, including 7 grandmasters, recently vied for the title in New York City. The defending champ Sammy Reshevsky led most of the way. Then he lost to Robert Byrne and Lubomir Kavalek, both undefeated, who managed to overtake Reshevsky in a 3-way tie for first prize. Since this tournament was a zonal, the first leg of the triennial world championship challengers cycle, a playoff will determine which two of these grandmasters will represent the USA at the interzonal in 1973.

Final Standings
1 Byrne 2 Kavalek 3 Reshevsky 4 Evans 5 Benko 6 DeFotis 7 Lombardy 8 Mednis 9 Bisguier 10 Martz 11 Kaufman 12 Feuerstein 13 Horowitz 14 Popovych	9 9 9 8½ 8 7½ 7½ 7 6½ 6½ 5 3 2½ 2

This instructive example of play on both wings is a candidate for the best game award. White achieves an early space advantage and breaks through on the Queenside but Black's defense is tenacious. Finally White switches to a Kingside invasion.

King's Indian Defense
White: EVANS 1 P-Q4 2 P-QB4 3 N-QB3 4 P-K4 5 B-K2 6 N-B3 7 0-0 8 B-K3 9 P-Q5 10 BxB 11 P-QN4 12 P-QR3 13 Q-N3 14 B-K2! 15 B-Q2 16 P-B3 17 N-R4 18 PxP 19 Q-B3 20 P-B5 21 P-N5! 22 QxKP 23 Q-B5 24 B-B3 25 KR-Q1 26 P-K5 27 P-K6 28 NxB 29 Q-B2 30 P-R3(b) 31 B-B4 32 N-K4 33 QxN 34 Q-K5 35 R-R4! 36 B-Q3 37 R/1-R1 38 QxQ 39 K-B2 40 P-R4 41 PxP 42 R-R1 43 R-KR5 44 P-N3 45 KxP 46 R-KN4 47 R/5xP 48 RxR 49 B-R7 50 K-B4 51 PxP 52 P-B7! 53 K-K5 54 R-N8ch 55 R-N7ch 56 RxN 57 R-QN7	Black: POPOVYCH N-KB3 P-KN3 B-N2 P-Q3 0-0 B-N5(a) KN-Q2 P-K4 BxN P-KB4 P-QR4 N-R3 K-R1 P-85 N-B3 R-KN1 PxP B-B1 P-KN4 PxP N-N1 QN-Q2 R-N3!

(a) Inferior. Usual is 6 … P-K4 7 0-0, N-B3 8 P-Q5, N-K2 (b) Unclear is 30 R-R7, P-N3 31 P-Q6, QxKP 32 RxP (or 32 PxP, R-B1 33 R-Q8, R-N2!), P-N5! (c) Better is 39 … P-R4. (d) Missing a draw: 50 … N-B6! 51 R-N8ch K-K2 52 RxR. KxR 53 K-K5, K-K2 54 K-Q4, N-N4ch 55 KxP. N-Q3ch 56 K-Q4, K-B3 with a blockade. (e) Looks natural, but 51 … N-B2! is the only drawing chance.

PROBLEM SOLUTION: 1 Q-K8! threatening 2 PxP. If 1 … P-Q3 2 N/5-Q7. If 1 … R-Q3 2 P-KB4

Problem Composing Contest
A $600 prize fund has been announced by the Piatigorsky Foundation for its 3rd international endgame and problem contest, open to composers anywhere in the world. Deadline for entries is December 31, 1972. All submissions must he originals never before published, accompanied by 2 diagrams with full solutions and all variations. No material will he returned. Submit to Pal Benko, Box 313, Gracie Station, NY, NY 10028.
The art of composing is alive and well; several prizes are offered in each of the four categories: 1. Endgame Studies ($75 $50 $35 $20 $10) 2. Two-move direct mates ($50 $40 $30 $20 $10) 3. Three-or-more-move direct mates ($50 $40 $30 $20 $10) 4. Helpmates ($40 $30 $20 $10).
In addition the best in each class by a U.S. composer will earn $25 credit for merchandise in the U. S. Chess Federation catalog (write Box E, 479 Broadway, Newburgh, NY 12550).
One of the judges is Benko, a grandmaster whose interest has drifted towards the realm of problems. He composed today's teaser in the shape of the numeral nine. But he also plays a mean game of chess, distinguished by an ultra positional style. Behold!

Curacao 1962 King's Indian Defense
White: BENKO 1 P-KN3 2 B-N2 3 P-K4 4 P-Q4 5 N-K2 6 0-0 7 QN-B3 8 P-QR4 9 P-R5 10 NxP 11 P-R3 12 R-K1 13 B-K3 14 P-B4 15 Q-Q2 16 PxPe.p. 17 P-QN4! 18 P-N5(d) 19 BxN 20 QxB 21 Q-Q2 22 QR-Q1 23 P-K5(e) 24 KxB 25 K-B2 26 PxP 27 RxR 28 Q-K2 29 Q-B3 30 N-K4 31 QxN 32 Q-B6 33 K-B3 34 P-N4 35 PxP 36 K-N2 37 R-KB1 38 KxR 39 Q-N2 40 Q-K2	Black: FISCHER N-KB3 P-KN3 P-Q3 B-N2 0-0 P-K4 P-B3 QN-Q2(e) PxP(b) N-B4 R-K1 KN-Q2 Q-B2 R-N1(c) P-QN4 PxP N-K3 NxN BxBch P-QB4 B-N2 R-K3 BxB Q-N2ch R-Q1 N-B3 PxR K-B2 Q-N1 NxN R-Q2(f) Q-Q1 K-N2 P-K4 R-B2ch Q-R5 RxR QxPch Q-K6 Resigns
(a) Getting cramped. Better is 8…P-QR4 to hold White back. (b) More prudent is 9…Q-B2 to stand fast in the center. (c) A faulty idea. Necessary is 14…N-B3 15 B-B2, B-Q2 followed by…QR-Q1, holding tight. (d) To create a “hole” on Black's Q4 square. (e) Snaring the backward QP, for if 23…PxP? 24 QxN wins. (f) If 31…RxP 32 Q-K5, R-Q1 33 R-Q7ch! forces a win.

PROBLEM SOLUTION: 1 N-K4! BxR/N6 (or 1…BxR/K6 2 R-N5) 2 R-K5 mate..
