Had Black on his first move played K. to R's sq., you still mcve 2. K. to Kt.'s 6th, Black must then move 2. K. to Kt.'s sq., and you advance R. P., and if he refuse to take it, play K. to B's 7th.

Then you gain a move, and place your King in the proper position

before advancing the Pawn.;

(He would equally lose by taking the Pawn.)

1. K. to B's 7th.

And wins.

Diagram 110.

With the move Black may draw the game, without it he must lose

KING AND TWO PAWNS AGAINST KING AND TWO PAWNS.

SOME interesting cases occur under this head, where the game may be wor or drawn by correct play.

Diagram 111.

This is a well-known position of Philidor's, who supposed, that if Black had the move, he would lose the game. This opinion, however, has been proved to be erroneous, the game being drawn whoever plays first. I White move, he plays :

WHITE.

1. K. to his 3rd.

2. K. to B's 3rd.

BLACK.

1. K. to his 4th.
2. K. to B's 4th.

(Were he to move K. to B's 4th, you would win by 3. K. to Q's 4th.)

3. K. to B's 3rd.

4. K. to Kt.'s 3rd.

5. K. to Kt.'s 4th.

3. K. to his 4th.

4. K. to his 3rd.

5. K. to B's 3rd.

And by continuing to play thus, Black may always draw the game.

2. Kt. takes B.

2. B. P. takes Kt.

3. P. to Q. Kt.'s 5th.

3. K. to B's 2nd.

(If to B's 3rd, White moves K. to his 4th, and the position becomes tha same as under in another move.)
