26. Kt - Kt 4 R - Kt 3
27. P - K 5 R - Kt 2
28. B - B 4 B - B 2

All these moves are practically forced, and as it is easily seen they tie up Black's position more and more. White's manœuvres from move 24 onwards are highly instructive.

29. Kt - B 6 Kt - Kt 3

This wandering Knight has done nothing throughout the game.

30. Kt (B5) - K 4 P - K R 3
31. P - K R 4 Kt - Q 4
32. Q - Q 2 R - Kt 3
33. P × P Q - B 1

If P × P; K - B 2, and Black would be helpless.

34. P - B 4 Kt - K 2
35. P - K Kt 4 P × P
36. P × P Resigns.

There is nothing to be done. If B - Kt 1; Q - R 2 ch, K - Kt 2; B × P.

The student should notice that, apart from other things, White throughout the game has had control of the Black squares, principally those at K 5 and Q B 5.

From now on to the end of the book I shall give a collection of my games both lost and won, chosen so as to serve as illustrations of the general principles laid down in the foregoing pages.
