No. 183. S. LOYD (Boston Gazette, 1859)

BLACK (10 men)

WHITE (6 men) wimp: to play and mate in two moves; solution next week. Solution to No. 182 (Dawson): B-QR 3, threat Kt-B 7.1 ...P-K 3; 2 Kt X P.1... P-K 4;

2 Q X R. 1 . . .QR any; 2 B-K 6. 1 . . . P-Kt 5;

2 P X P. 1 ... Kt any; 2 Kt-Kt 4. Three good tries- 1 Q-Q 87, B-K 41, 1 B-Q 4?, PXPI, 1 P-Kt 4, Kt moves I-combine with actual play to make up an excellent problem.

Perhaps the best new Russia.n star to arise in the last few years is Leonid Stein; in this week's game he wins a fascinating struggle against Tal. This was won at a time when Tal-still in poor health-was going through a bad patch; in this game we see

equal brilliance and resource shown by the two players but Stein's is soundly based where Tal's is not. The latter's play is too impatient and ignores the realities of the position.

13 Q-B 4 B-K 2. 13 . . , P-1( 4; 14 QxBP, PxKt; 15 BXP ch, K-Q 2; 16 QXP or 16 Kt-Q 5 with more than enough for the piece. 14 Q-Kt 4! 0-0-0? Too bold: 14 . . . K-B 1; would be better though White's position is still preferable. 15 B-Q 5 P-Kt 5? Again too ambitious: he should either dislodge the powerfully placed WQ with P-R 4 or consolidate with Q-11 2. 16 BXB ch Exit 17 Kt-Q 5! PxKt The tempting 17 . .

27 Q--. K-B 1! . 13 meets4 beautifully simple rejoinder.
