15. gxf5 |
White certainly does not want to allow Black's f-pawn to advance further! Black would then have a fine game. | ||||
| | |||||
|
15... gxf5 16. exf5 Rf7 |
(!?) For the moment, Black dare not take the f-pawn, owing to 16...Bxf5 17.Bxf5 Rxf5 (17...Nxf5? 18.Bxf8) 18.Bxg7+ Nxg7 19.Rxg7 Kxg7 (20...Rxf3?? 21.Qxh7#) 20.Qxf5 and White emerges from the massacre with an extra piece. The purpose of this rook move was to unpin the g7-knight, allowing the recapture at f5. During the game, I thought 16...Rf6 more accurate, as it obviated White's next move. But 16...Rf6 17.Bg5 with 18.f6 to come would have been similar to a line discussed after Black's next move. | ||||
| | |||||
|
17. f6 |
(!) Opens up the b1-h7 diagonal for the Q and B already aligned thereon. White wins a pawn, but also has a strong attack. | ||||
| | |||||
|
17... Bxf6 |
(!?) After this Black comes in for a lot of pressure. I thought 17...Rxf6 might have been the better option, but as earlier remarked, now I'm not so sure. After 17...Rxf6 18.Bg5 Rf7 19.Bxh7 Bxg5 20.Nxg5 Rf8 (20...Rf4 gets exactly the same response) 21.Qg6! doesn't look too flash for Black at all. | ||||
| | |||||

18. Bxh7 |
When a pair of bishops is buried deep in the enemy position, you know there is some serious missionary work going on! | ||||

18... Qd7 |
What else is there? Black hopes to bolster his second rank defence line. | ||||
| | |||||
|
19. Bg6 Rf8 |
The alternative, 19...Re7, would have got the same response... | ||||
| | |||||
|
20. Ne4 |
White has an undoubted advantage now, with plenty of open lines into the Black position, and the White knights starting to pile in, as well. | ||||
| | |||||
|
20... Qe7 |
It can't be helped: Black must lose material. | ||||
| | |||||
|
21. Bxe8 |
Eliminating one of the defenders of g7... | ||||
| | |||||
|
21... Rxe8 |
(?) Relatively speaking, a disastrous move. But as Black was already in serious trouble, it really just accelerates his downhill progress. 21...Nxe8 lost at least the exchange (22.Bxf8), and 21....Qxe8 22.Nxf6 was even worse. No wonder the rook capture would have seemed the least of all evils... | ||||
| | |||||
|
22. Nxf6 |
A smashing blow, attacking e8 (Nxe8), g7 (Bxg7+) and h7 (Qh7#) simultaneously, and the BQ dare not take the knight owing to Bxg7+ winning the queen. | ||||
| | |||||
|
22... Nf5 |
Slender though it is, Black's best hope... Places an extra defender protecting g7, and the h7-square is also protected. Too bad about the rook... | ||||
| | |||||
|
23. Bg7+ |
(!) Played anyway! Much more decisive than 23.Nxe8(?). | ||||
| | |||||
|
23... Nxg7 |
Shortening the game. Black had to capture, but the alternative was not much less lethal: 23...Qxg7 24.Rxg7 (threatens, incidentally, 25.Rh7#) 24...Kxg7 (24...Nxg7 25.Qh7#) 25.Nxe8+ Kf8 26.Nc7 Rb8 27.Ne6+ etc. | ||||
| | |||||
|
24. Qh7# |
Checkmate. Black was doing fine up until the mistimed pawn break (14...f5?) after which his game went downhill fairly quickly. Yet the pawn break was exactly what Black aims to play in this opening. The line suggested after 13...Ng8 14.Be3 f5! looked OK for Black. Maybe that's the key: 13...Ng8 is to be preferred to 13...Ne8. It was certainly not obvious during the game that this might be so, but after the latter move, it seems that it might be difficult for Black to arrive at ...f5 safely. | ||||
