6. P - Q 3 B - K Kt 5
7. B - K 3 B × B

This opens the K B file for White, and also reinforces his centre, but Black naturally did not want to make a second move with this Bishop.

8. P × B Q - K 2
9. O - O O - O - O

Bold play, typical of Janowski.

10. Q - K 1 Kt - R 3

The problem for White now is to advance his Q Kt P to Kt 5 as fast as he can. If he plays P - Q Kt 4 at once, Black simply takes it. If he plays first P - Q R 3 and then P - Q Kt 4, he will still have to protect his Q Kt P before he can go on and play P - Q R 4 and P - Kt 5. As a matter of fact White played a rather unusual move, but one which, under the circumstances, was the best, since after it he could at once play P - Q Kt 4 and then P - Q R 4 and P - Kt 5.

11. R - Kt 1 ! P - B 3
12. P - Kt 4 Kt - B 2
13. P - Q R 4 B × Kt

He simplifies, hoping to lighten White's attack, which will have to be conducted practically with only the heavy pieces on the board. He may have also done it in order to play Kt - Kt 4 and K 3.
