A better plan would have been to play R - K 1, threatening P - K 6.
| 18. ........ | R × R | |
| 19. R × R | R - K 1 | |
| 20. P - B 3 | P - Q B 3 |
Of course if B × P; Kt × B, Q × Kt; R - K 3. Black with a Pawn minus fights very hard.
| 21. R - K 3 |
The Pawn had now to be defended after Black's last move, because after B × P; Kt × B, Q × Kt;
R - K 3, Black could now play Q - Kt 1 defending the Rook.
| 21. ........ | P - Q B 4 | |
| 22. K - B 2 | P - Kt 3 | |
| 23. P - R 4 |
White's plan now is to fix the Queen's side in order to be able to manœuvre freely on the other side, where he has the advantage of material.
| 23. ........ | Q - Q 2 | |
| 24. R - Q 3 | Q - B 1 | |
| 25. Q - K 4 | Q - K 3 | |
| 26. R - Q 5 | K - B 1 | |
| 27. P - B 4 | K - Kt 1 |
