Chess Strategy
12. QxKt Kt-R4
13. B-B2 Kt-B5
A very dangerous manoeuvre, as White can evade the exchange of
his Bishop and the Black Kt does not get back in time for the
defence of the K side, where White's attack becomes virulent. He
should have played P-QB4 followed by Kt-B3.
14. Q-Q3 P-Kt3
15. B-R6 KtxKtP
16. Q-K2 R-K1
17. Kt-Q4
Black had probably anticipated that White would be content with
regaining his pawn by BxP, but, with fine positional insight, he
retains his Bishop for the coming onslaught and speedily
concentrates his forces on the K side; whilst Black, who has won
a pawn at the expense of several moves, cannot mobilise an
equivalent number of pieces in time for the defence.
17. ... Kt-B5
18. P-B4 B-Q2
White was threatening 19. Kt-B6, 20. KtxB, 21. B-Kt5, 22. B-B6;
18. ... Q-Q2 is not sufficient, as 19. P-B5 would follow. Neither
can 18. ... B-QB4 be played because of 19. B-Kt5, Q-B1; 20. B-B6.
Preferable to the text move seems B-KB1 (19. B-Kt5, Q-B1; 20. B-
B6, B-Kt2), as then the Black pieces have more freedom of action.
19. QR-K1 P-QB4
20. P-K6
A brilliant sacrifice to which no satisfactory reply can be
found. For instance, 20. ... PxKt; 21. Q-Kt4, Kt-K6, 22. RxKt,
PxR; 23. P-B5, BxP; 24. PxB, PxP, 25. BxP, etc.; or 24. ... R-
KB1; 25. PxPch, RxP; 26. Q-K6, Q-K1; 27. BxP, etc.; or 23. ... P-
Kt4; 24. PxPch, KxP; 25. Q-R5ch, K-Kt1; 26. P-B6, BxP; 27. BxP,
etc.; or 21. ... B-B4; 22. PxPch, KxP; 23. BxPch, PxB; 24. P-B5,
etc. There are many variations, all leading to a speedy end.
