K - Q 2 would not help much, but since he made the previous move he should now be consistent and play it.

18. K - K 4 R (K 3) - K 2

27. Kt P × P R - Q R 6
28. P - Q 5 Resigns.

The winning tactics in all these endings have merely consisted in keeping the opponent's Rooks tied to the defence of one or more Pawns, leaving my own Rooks free for action. This is a general principle which can be equally applied to any part of the game. It means in general terms—

Keep freedom of manœuvre while hampering your opponent.

There is one more thing of great importance, and that is that the winning side has always had a general strategical plan capable of being carried out with the means at his disposal, while often the losing side had no plan at all, but simply moved according to the needs of the moment.

30. ROOK, BISHOP AND PAWNS v. ROOK, KNIGHT AND PAWNS

We shall now examine an ending of Rook, Bishop and Pawns against Rook, Knight and Pawns, where it will be seen that the Rook at times is used in the same way as in the endings already given.
