White’s last eight moves completed his development, and his Bishops lie in wait for the attack on the Black King.  Meanwhile Black has effected nothing.  On the contrary, he

has exchanged his valuable KB, and also allowed his KKt to be driven off.  His King’s side is bare, and castling would be fraught with danger.  If Black castles now, White plays Kt-Kt5, and Black must weaken his position by P-R3 or P-Kt3, and White would advance his KtP or RP and force an exchange, opening a file for his Rook.  In consequence Black decides to forfeit castling and to bring his KR to bear on the KB file.  For this also Black must first play P-R3, and White obtains an open file by P-Kt4- Kt5.  The sequel is shown here.

22. ...  P-R3 23.  P-Kt4 Kt-K2 24.  RxRch BxR 25.  Kt-K1

White waits first, to see whether Black is going to castle, and meanwhile tries to exchange Black’s QKt, which commands his QB2 and Q3.

This provides against Black attempting to free his Bishop by P-K4.  Black’s B-Q2 is countered by B-Kt6ch.  White new wins surprisingly quickly, through the greater mobility of his pieces.

34.  R-Kt1         R-R1
35.  K-R1          R-R5

Here Black could have held out a little longer by defending his KtP:  35. ...  K-B1; 36.  R-Kt3, R-R5; 37.  Q-Q1, K-Kt1; 38.  B-Kt5, QxP (RxP, 39.  Q-R5); 39.  R-Q3, QxP; 40.  BxR, QxB.

          36.  Q-Kt3 RxP

Compulsory.  B-Kt5 was threatened, and after R-R1, QxP, QxQ, RxQ, the RP wins easily.
