White did very properly to take the P. with the B., because after the exchange of pieces, he has to move, and the R. Pawns being at equal distances from their eighth sq., of course he makes a Q. first. Black did wrong to take the B., because he made it easy for the White to win; he ought to have moved his King.

Two Pawns not passed on adjoining files.

It is evident that neither of the Pawns on the Q.'s side can advance to Queen without being put en prise; he who is first obliged to put his P. en prise will not win, nor will he always lose, as shall presently be shown. Suppose that in

his position you have the move, you will win by playing as follows:

BLACK.

1. Q. Kt. P. one.

WHITE.

1. Q. R. P. one.

2. If you were to take the P. you would play ill, be. cause you would stale-mate the Black instead of winning; you should play,

5. P. becomes a Q. or R. and check-mates.

It sometimes however happens that you carnot win, for

xample:

5. Q. checks at Q. Kt. 8th, and then takes Q. Kt. P..

winning easily.

One Pawn against two united Pawns.

FIRST POSITION.

The two Pawns will win. Though this is a simple and easy position, yet it is not indifferent with which Pawn the White begins, for if he were to play Q. Kt. P. one sq., Black would advance Q. Kt. P. two sq., stopping the white Pawns, and supposing White had nothing else to play, he would be obliged to sacrifice Q. B. P., and each party would make a Q. White ought to begin with Q. B. P. one sq., then Q. Kt. P. one sq., and afterwards Q. B. P. In the following position, by taking proper advantage of your isolated P., you win the game.

WHITE.

SECOND POSITION.

(See next Diagram.)

White to move.

1. Kt. to Q. 5th, check.

2. Kt. takes B.

1. K. to K. Kt. 2d.

2. Q. R. P. or Q. B. P. takes Kt.

3. Q. Kt. P. one: this is the move which decides the game in your favor, as you thereby prevent the advance of

10. K. to R. 6th.

10. Is compelled to advance the

P., which you take, and in two moves making a Q. or R. 'you check-mate.

In this situation, as neither of the Kings can quit the Pawns on the King's side, the game will depend entirely on the manner of playing the Pawns on the Queen's side. Whe ther you have the move or not you should begin with Q. R. P. one sq., then Q. Kt. P. one sq.; afterwards Q. R. P. one sq.;
