13. Q. Bishop to K. B. fourth sq. 14. Q. Bishop to K. Kt. third sq. 15. K. to R. second square

Black wins.

(a) This is a bad move; it is generally dangerous to allow the Kt. to enter your game, if supported by K. B.*

(b) To prevent your playing Q. B. to his K. Kt. fourth square.

(c) Perceiving that he ought to remove the K. from his present dangerous situation, he plays Q. B. P. to support Kt. This move also prevents your Q. Kt. from attacking him.

The Amateurs denounce this move as bad, and yet make Black come off with the best game; supposing White to adopt the strongest moves, see Game VIII.

(a) If you were to take K. P. with P., he would take Kt. with B., and then play K. R. to B. square.

(b) If you had retaken K. B., he would move K. R. to B. square.

*Not so strong as Q. P. two, whieh ought also to be played next move.

* Your safest play is to move R. to K. B square, but Black will still get the better game by advancing Q. P. two squares.

In this situation the game is equal; indeed, of the two Black is the most advantageously posted. The very different results of these variations on the same game show the importance of not losing a move; and the absolute necessity of playing correctly, as well for the attack as the defence.

*The following is stronger play :-
:-

6. Q. P. attacks Kt.-If he retreat Kt. to Q. third, you win Q. by playing Kt. to Q. sixth. Kt. to K. B. third square

7. K. B. to Q. Kt. third, with the better position.

(a) If he had played King to Knight square, you would either win Q. or give checkmate in two moves, by advancing Kt. to K. Kt. fifth.

8. Q. B. P. one square (bad) (A.)
9. Q. Kt. to B. third square
10. Q. Kt. to Q. Kt. fifth square

Black now forces mate in two moves at most.

(a) This is not the strongest move; but it is not so bad as to decide the fate of the game.

SECOND GAME.

(a) It would be bad play to push Q. B. P.

(b) His Queen is now ready to support the Pawns.

(c) Your Queen is moved that your Pawns may advance.

(d) In order to make an opening on your K., with K. R. P.

(e) By castling with Q. R. he is enabled to move his Pawns with greater effect against your King. It would have been wrong to take Q B. P., because your Q. P. and B. P. being united, would impede the action of his pieces.
