Chess Strategy
11. KxP K-B4
At last Black has captured the coveted square, whilst keeping the
spare move in hand.
12. K-B2 K-B5
The White King cannot move to Kt2 now, because in that case Black
would move the King to the White QBP and queen in seven moves,
and White, after seven moves, would only have the KB pawn at B7.
13. K-K2 K-Kt6
14. K-K3 P-B4
and wins, for White cannot hold the KBP now, but must capture the
KtP in exchange for it, after which the Black King reaches the
Queen's side two moves ahead, e.g.:
15. K-K2 K-Kt7
16. K-K3 K-B8!
17. K-K4 K-B7
18. K-B5 KxP
19. KxP K-K6, etc.
Black would have forced a win also if White had played K-Kt2 on
his twelfth move thus: 12. K-Kt2, K-B5; 13. K-B2.
Now White has the opposition, and after Black wrings it from him
by playing the spare move P-B4, he assumes it again with 14. K-
K2, K-Kt6; 15. K-K3. But he cannot maintain it after Black's K-R6
because the square at Q3 for distant opposition is not
accessible. After 16. K-Q2, K-R7!; 17. K-K3, K-Kt6; 18. K-K2, K-
Kt7; 19. K-K3, K-B8 we get the same result as before.

Diag. 83.
White has the advantage, because Black must keep either his King
or his Knight permanently near the passed pawn, guarding against
its advance, whilst both White's King and Knight can attack the
Black pawns. As yet they stand so far in the rear that the White
King cannot approach them Therefore White must first try to force
their advance.
1. Kt-B5 P-Kt3
2. Kt-Q3 P-R4
This is now necessary, because the square B3 is weak after P-Kt3
and the White Knight threatens to win the Rook's pawn eventually
with a check at B6. For this reason Kt-Q 2, for instance, could
not be played instead of the move in the text, because 3. Kt-K5
would follow. Black now cannot exchange, of course, otherwise the
position would resolve itself to an easy end game win similar to
the one in Diagram 56. There would be nothing left but Kt-Kt1 to
oppose the threat of Kt-B6ch, and this would get the Knight
entirely out of play, so that White could queen the passed pawn
easily after 4. K-Kt6.
3. K-K5 P-B3
The King was threatening to enter via Q5 and B6.
4. K-B5 Kt-K3
If Black wishes to obviate the threat: Kt-K5-B4, and plays P-Kt4,
the White King goes to QB5 and wins all the pawns easily.
Therefore Black endeavours to sacrifice a pawn in order to
exchange the two others, after which a draw could be forced by
exchanging the Knight for the remaining White pawn.
5. Kt-K5 P-B4
6. Kt-B4 P-Kt4
7. KtxP P-B5
