This is a mistake. Black is unaware of the danger of his position. He should have played P - Kt 4; threatening R - R 3, and, by making this demonstration against White's K R P, stop the attack against his Queen's side Pawns, which will now develop.
He could not play K - Q 3, because P - Q B 4 would win at least a Pawn. This in itself condemns his last move K - K 3, which has done nothing but make his situation practically hopeless.
Now forced, but it is a little too late. He could not play 8...K R - B 2, because P - K B 4 would have { 130} left his game completely paralysed. Black now finally awakens to the danger, and tries to save the day by the counter-demonstration on the King's side, which he should have started before. Of course, White cannot play R × R P, because of R × R, followed by R - R 3, recovering the Pawn with advantage.
Black is now in a very disagreeable position. If he played 9...P × P; 10 R × P would leave him in a very awkward situation, as he could not go back with the King, nor could he do much with either Rook. He practically would have to play 10...P - K R 3, when White would answer 11 P - Kt 4, threatening to win a Pawn by P - Kt 5, or, if that were not enough, he might play K - Q 4, to be followed finally by the entry of the King at B 5 or K 5.
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.
12. ........ K - Q 3 13. P - Kt 4 R - Q Kt 2
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.
