P - K R 4, to be followed by P - Kt 4, might have been a more vigorous way to carry on the attack. Black's weak point is unquestionably the Pawn at K 4, which he is compelled to defend with the King. The text move aims at doubling the Rooks, with the ultimate object of placing one of them at Q 6, supported by a Pawn at Q B 5, Black could only stop this by playing P - B 4 which would create a "hole" at Q 5; or by playing P - Kt 3, which would tie the Black Queen to the defence of the Q B P as well as the K P, which she already defends. Black, however, can meet all this by offering the exchange of Rooks, which destroys White's plans. For this reason P - K R 4 appears the proper way to carry on the attack.

This move is preparatory to P - K Kt 3, which would
make Black's position secure. Unfortunately for Black, he did not carry out his original plan.

P - K Kt 3 would have left Black with a perfectly safe game.
| 22. R × R | R - Q 1 |
A very serious mistake, which loses a Pawn. P - K Kt 3 was the right move, and would have left Black with a very good game. In fact, if it should come to a simple ending, the position of the Black King would be an advantage.
