19. h4
|
There is no real hurry to defend f2, and I can use the tempo in order to gain more control and more threats on the kingside.
Note that the black queen is doing almost nothing, and the Blsb is useless. |
 
|
| |
|
|
19... Raf8
|
Still not a real threat. |
|
| |
|
|
20. h5 g5
|
Of course, but now... |
|
| |
|
|
21. h6
|
Hmmm... what an annoying pawn I have! |
|
| |
|
|
21... Rf7f3
|
This rook is not annoying at all. But my attack is stopped. How to progress?
The only piece that can do something is my queen. So, even if it takes a long way, let's put it in the fight. |
|
| |
|
|
22. Qd2 Qd8
|
At last. But this is not the best move for the queen, in sight of what's coming. |
|
| |
|
|
23. Qd4
|
I know I am giving away the f2 pawn, but no risk, no gain. But NOW I have a plan, a tactic. If I remove the dsb, black is forced to defend the mate in g7 (this is why I said the black queen was not very well relocated some moves ago). Nothing really special, but still... |
|
| |
|
|
23... Rf3xf2
|
Is black seeing that after 24. Bg3, his only move that doesn't lose a quality is Rf2-f6? |
|
| |
|
|
24. Rh5
|
This allows black to spend some tempoes in doubling rooks on the second row. There must be some "hole" in black's position... g5 is, no doubt. |
|
| |
|
|
24... Rg2
|
Falling in the trap. |
|
| |
|
|
25. Bf4
|
And this is the key. I think I've won, now. |
|
| |
|
|
25... Rf7 26. Rxg5+ Kf8 27. Qh8+
|
The purpose of moving the king from g. |
|
| |
|
|
27... Ke7 28. Rg8
|
Threating Bg5+ as well. |
|
| |
|
|
28... Qd7 29. Bg5+ Kd6 30. Rd8
|
Forced material gain. But black could have tried Rf7-f2, being just a tempo from drawn for perpetual check.
White should have played RxQ+, KxR, Qxh7+, Kc6 or c8, also winning because of the h pawn (since white should have lost his queen for the two rooks), but with an interesting resistance. |
|
| |
|
|
30... Qxd8 31. Qxd8+ Kc5
|
Now there are a couple of lines to mate, very nice. |
|
| |
|
|
32. Be7+
|
If Kc6, Qd6+, Kb5, Qd7+, now if Bc6, white has Qxa7, that forces black to avoid a4# by something like RxB (but a4!, Kc5, QxR#) or Bsomewhere, with no much more ways to escape. |
|
| |
|
|
32... Kc6 33. Qd6+ Kb5 34. Qd7+ Ka5
|
Bf6 could have resisted a little longer, as explained, since a4+ is not the best move: Kxa4, if QxBf6+, Ka5, Bb4+, Ka6, Qa4+ Kb7.
And if Kxa4, Qxa7+, Kb5.
White should win with Bf6 Qxa7!, but it is a little harder to see.
The text move, unfortunately, loses at once, since the escape square b7 is blocked by the bishop. |

35. Bb4+ Ka6 36. Qa4#
