P - Q R 4, in order to maintain the White B in the dominating position that it now occupies. This would have been met by Q - B 2; second, either of the Rooks to Q 1 in order to threaten 16 P × P, B × P; 17 Kt × B, Q × Kt; 18 B × P ch. This would have been met by B - Kt 5; and third, P - K R 3 to prevent B - Kt 5 and by playing either R to Q 1, followed up as previously stated to force Black to play P - Q Kt 4, which would weaken his Queen's side Pawns. Thus by playing P - K R 3 White would have attained the desired object. The text move blocks the action of the White B and facilitates Black's development. Hereafter White will act on the defensive, and the interest throughout the rest of the game will centre mainly on Black's play and the manner in which he carries out the attack.
| 15. ........ | Q - B 2 | |
| 16. B - Q 3 |
(This seems wrong, as it makes the development of Black's Queen wing easier. At present he cannot play P - Q Kt 3, because of the reply P × P followed by B - Q 5.)
| 16. ........ | P - Q Kt 3 | |
| 17. P - B 4 | B - Kt 2 | |
| 18. K R - B 1 |
(With the idea of Q R - Kt 1 and P - B 5. But it only compels Black to bring his B to Q B 4, which he would do in any case.)
| 18. ........ | B - K 2 | |
| 19. R - B 2 | B - B 4 | |
| 20. Q - Kt 2 | P - B 3 |
(It would have been better, probably, to play 20...K R - K 1, with the idea of P - B 4 presently.) Black's play hereabout is weak; it lacks force, and there seems to be no well-defined plan of attack. It is true that these are the most difficult positions to handle in a game. In such cases a player must conceive a plan on a large scale, which promises chances of success, and with it all, it must be a plan that can be carried out with the means at his disposal. From the look of the position it seems that Black's best chance would be to mass his forces for an attack against White's centre, to be followed by a direct attack against the King. He should, therefore, play Q R - K 1, threatening P - K B 4. If White is able to defeat this plan, or rather to prevent it, then, once he has fixed some of the White pieces on the King's side, he should quickly shift his attack to the Queen's side, and open a line for his Rooks, which, once they enter in action, should produce an advantage on account of the great power of the two Bishops.

(White has clearly lost time with his Rook's moves.)
