Initiating an attack to which there is no reply, and which has for its ultimate object either the winning of the White Q B or cutting it off from the game. (Compare this game with the Winter-Capablanca game at Hastings.)

17. P - K R 4 P - B 5

The Bishop is now out of action. White naturally counter attacks violently against the seemingly

exposed position of the Black King, and, with very good judgment, even offers the Bishop.

18. P × P ! P × P !

Taking the Bishop would be dangerous, if not actually bad, while the text move accomplishes Black's object, which is to put the Bishop out of action.

19. R - R 1 B - B 2
20. K - Kt 1

This move unquestionably loses time. Since he would have to retire his Bishop to R 2 sooner or later, he might have done it immediately. It is doubtful, however, if at this stage of the game it would be possible for White to save the game.

20. ........ Kt - K 4
21. Kt × Kt R × Kt
