Diag. 84.
8. K-K5 Kt-B4
9. Kt-B6ch K-B1!
Not K-B2, because of 10. K-Q4, Kt-Q6; 11. Kt-K5ch.
10. Kt-R7
Here White had only considered the following answer:
Kt-Q6ch; 11. K-Q4, KtxKtP; 12. KtxP, Kt-Q6; 13. P-B5, Kt-Kt5; 14.
Kt-B3, Kt-B7ch: 15. KxP, Kt-K6ch; 16. K-B5, KtxP; 17. P-R4, Kt-
K2; 18. Kt-Q5, Kt-B1; 19. K-B6, K-K1; 20. K-B7, Kt-R7; 21. K-Kt7,
and wins the Knight.
Black however draws, through a pretty combination:
10. ... P-Kt5
11. K-Q4 P-B6
12. K-B4 PxP
13. KxP KtxP
and White cannot prevent the ultimate exchange of Kt for P. The
last winning chance would have been: 10. K-Q4!, Kt-Q; 11. K-B3.
This is in any case the more plausible line, because now White
can attack the pawns with both King and Knight, as both the Black
pieces are away from the field of operations. The sequel could
be: 11. KtxBP; 12. P-R3 (Kt-R7 would only draw: Kt-K7ch; 13. K-
Kt4, Kt-B8 14. P-R3, Kt-R7ch; 15. KxP, P-B6); 12. Kt-Q4ch 13. K-
Q4, Kt-B5; 14. K-K4 (Kt-R7 ?, Kt-K7ch!!; 15 K-K3, P-B6), Kt-Q6;
15. P-Kt4, Kt-Kt7 16 Kt-Q4, and wins
III. From a game Blackburne-Schlechter (Vienna, 1898).

Diag. 85
White has just played Q-B4. P-B5 is threatened, and Black is
forced to exchange Queens. The ensuing end-game, however, is
inferior for Black, because the QP is weak and White threatens
eventually to force his Queen's Pawn through.
1. ... Q-B4
2. QxQ BxQ
3. Kt-Q4 B-Kt3
4. RxR RxR
5. R-K1 RxR
If Black wants to avoid the exchange, he must yield up the King's
file to White, and that would surely spell disaster, as the Black
Rook would have no field of action, and would have to go to Q1 to
avoid the loss of a pawn through Kt-Kt5ch, after which the White
Rook would take possession of the seventh rank, fettering the
action of the Bishop into the bargain.
6. KxR B-Q6
7. P-QKt3 K-Q2
Black is condemned to inactivity, and White can quietly set to
work to force his pawn through.
8. K-Q2 B-K5
9. P-Kt3 B-Kt8
10. P-QR3 B-K5
