If now White plays P-Q4, he loses a piece by PxP; 24. KtxP?, RxR; 25. KxR, Q-B3ch.

23. R-K1

The Rook has no future here, and R-Q1, in order to play P-Q4, is more logical. But as Black obviously threatens to double his Rooks on the KB file, it would be advisable to play for an exchange of Rooks, with: Kt-Kt2, QR-B1 and Kt-K1.

23. … R-B2 24. QR-K2 QR-KB1 25. Kt-K1 Kt-Q5 26. R-Q2 Q-Kt4 27. Kt(K3)-Kt2 BxKt 28. KxB

KtxB is frustrated by Kt-B6ch.

28. … Q-K6

All the Black forces are now in action, and White has no defence, as his pieces can hardly move.

29. K-B1 Kt-Kt6!
