or e5, that is away from the corner to which he is to be driven.

The correct way of maneuvering for White will be to confine
Black's King to a smaller and smaller territory until he finally
has to back up against the side or the corner of the board. This
consideration indicates the following line of play:

(1)Q-f5, K-c6; (2)Q-e5, K-d7; (3) K-c4, K-c6; (4) Q-e7, K-b6; (5)
Q-d7, K-a6. White must now be very careful to avoid a stalemate
which would result if he deprived the King of all mobility
without attacking him at the same time. This would be the case if
he now moved Q-c7. For then Black could not move the King to b5,
as this square is controlled by White's King, and he could not go
to any of the other four squares in his range on account of
White's Queen attacking all of them. The correct move is (6) K-
c5. This leaves only the square a5 for Black's King, and White
checkmates by (7) Q-a7 or (7) Q-b5.

If, in Diagram 9, White had a Rook on h3 instead of the Queen,
the mating process would take a few more moves, but there would
be no escape for Black either.

It will again be White's aim to confine Black's King to a smaller
and smaller number of squares. The best way to start will
therefore be (1) R-e3. No matter what Black replies, he cannot
prevent White from driving him to the edge of the board in a
similar way to the one shown in the following example:

(1) ..., K-d5; (2) R-e1. This is a WAITING MOVE. Black must leave
d5, thus enabling either White's King to advance or the Rook to
