DIAGRAM 21.

On the next move White will, therefore, take the Pawn calling
Check and at the same time attacking the Rook a8. The King must
move and the Knight takes the Rook.

Quite frequently a similar attack with the Knight is likely to
win the Queen if the opponent is not familiar with situations of
that kind. If in the position of Diagram 21 White plays (1) Kt-
d5, Black must protect the Pawn c7 by Q-d8 or Q-d6, but not by Q-
c6; for in the latter case White would continue with (2) B-b5,
Qxb5; (3) Ktxc7+ and (4) Ktxb5.
