DIAGRAM 10.

There are possibilities of a player mating his opponent with only
King and Knight or King and Bishop, but then there must be a man
of the opponent blocking the escape of the King. Diagram 10 is an
example of such a case. White plays (1) Kt-c5, K-h1; (2) Kt-e4.
Now Black cannot continue with P-h2, as White would checkmate
with Kt-g3. Therefore, he must play (2) ..., K-h2. White then
gets the Knight in such a position as to deprive Black's King of
the escape to h2 and to keep the square g3 accessible to the
Knight: (3) Kt-d2 (not Kt-g3, which would stalemate Black's
King), K-h1; (4) Kt-f1. The only move left to Black is now P-h2,
and White mates by (5) Kt-g3.

If it were Black's move in the position of the Diagram the game
would be a draw, for after (1) ..., K-h1; (2) Kt-c5, P-h2 Black
is stalemate unless White moves his King so as to make the square
g1 accessible to Black. However, he will not do that as it would
enable Black to queen the Pawn and to win the game.

In the case of King and Bishop against King and another man a
mate can only occur through a blunder. Supposing for instance
White has the King on f3 and a Bishop on d5 and Black has the
King on h1 and a Bishop or a Pawn on h2, then White on the move
