21. Nd5 |
This is a very clever move. If Black plays B(c6)xN(d5) then White can mate in two starting with R(e2)xR(e8) | |||||||||

26... Bxf3 |
This seems to me o be the obvious move, but PMCA gives it as a mistake and suggests Qb4 27. Re5 Qxb2 28. Rxe8+ Bxe8 29. Qd2 Qb1+ 30. Qe1 Qxe1+ 31. Nxe1 Kf8 32. d4 Ke7 33. Nd3 Bc6 34. Nf4 Kd6 35. Nh5 g6 36. Nf6 h6 as the best continuation for Black. | |||||||||

27. gxf3 |
White's king side pawns are now split, but Black has to be careful as her own back rank is weak, for example if Re8-e6?? Rc5-c8 mating! | |||||||||
| | ||||||||||
|
27... Qb4 |
With a double attack on the Rc5 and also threatening Re1 forking king and queen. | |||||||||
| | ||||||||||
|
28. Rc1 |
So the rook drops back, and White's pawns start to drop. PMCA gives 28. Qc2 h6 29. Rc8 Rxc8 30. Qxc8+ Kh7 31. Qf5+ Kg8 32. Qe5 Qa4 33. Kg2 Qxa2 34. Qe8+ Kh7 35. Qe4+ g6 36. Qxb7 Kg7 37. d4 as a better alternative, but not many players would allow checks on e1. | |||||||||

So one pawn goes | |||||||||

29. Kg2 |
This doesn't seem to achieve much. PMCA gives 29. Rb1 Qxa2 30. Rxb7 Qd5 31. Ra7 Qg5+ 32. Kf1 Qh6 33. Kg2 Qg6+ 34. Kf1 Qh5 as better. At least White's deficit is held to just one pawn in this line! Another way to save the second pawn would have been Rc1-c2 | |||||||||
| | ||||||||||
|
29... Qxa2 |
Losing a second pawn makes things hard for White | |||||||||
| | ||||||||||
|
30. Rc2 |
White hits the queen, but only to drive it to a better square | |||||||||
| | ||||||||||
|
30... Qd5 |
It is nicely centralised here, ready for action on either side of the board. | |||||||||
