Now White can neither take the Kt nor the R. In the first case Q- R5ch forces mate very soon, in the second B-B7ch, followed by B- Kt5ch or B-R3ch, wins the Queen.
11. P-Q4 Q-B3! 12. BxKt Q-R5ch 13. K-Q2 QxB 14. Q-B3 Q-R5! 15. P-Kt3
Not QxR, because of Q-B7ch and the loss of the Queen by a discovered check by the Bishop.
Q-Kt4ch 16. Q-K3 Q-Q4 17. R-K1 B-Kt5 18. K-B2 P-QR4
Such is the price to pay for premature advances.
19. PxP RxP 20. B-R3 P-QB4
Black shatters White’s pawn position, and his Bishops and Rooks have full play along open files and diagonals.
21. PxP RxB! 22. KtxR
or PxB, RxRPch; 23. RxR,QxRch; 24. K-Bl,B-B4.
22. … BxP
