Again he cannot play P - K R 4, because P - K B 4 would leave him paralysed. The advance of his K R P would make White's K R P safe, and consequently his K R would have to retire to K B 2 to defend the Q R P. That would make it impossible for his King to go to Q 2, because of the Q R P, nor could he advance a single one of his Pawns. On the other hand, White would play P - Kt 4, threatening to win a Pawn by P - Kt 5, or he might first play K - Q 4, and then at the proper time P - Kt 5, if there was nothing better. Black meanwhile could really do nothing but mark time with one of his Rooks. Compare this bottling-up system with the ending in Example 57, and it will be seen that it is very similar.

Probably wrong. P - Kt 4 at once was the right move. The text move gives Black good chances of drawing.

This could never have happened had White played 12 P - Kt 4, as he could have followed it up by P - Kt 5 after Black's K - Q 3.
| 14. P - R 5 |
Not good. P - K B 4 offered the best chances of
winning by force. If then 14...R - Kt 2; 15 P - R 5, R - Kt 7 ch; 16 K - Q 3, R - K R 7; 17 R × P, R × R; 18 R × R, R × P; 19 R - R 6, with winning chances.
