21. Ra5 
 | 
Winning a pawn | 
   
    | 
|   | 
| 
 | 
21... Nh5 
 | 
This move does nothing to assist black's attack, white's king is solidly defended, blacks best bet would be to attack White's splintered queenside pawns with Bf5 | 
   
    | 
|   | 
| 
 | 
22. Nxb5 
 | 
White gets greedy, better would be Kh1 in order to win the Bishop | 
   
    | 
|   | 
| 
 | 
22... Rf6 
 | 
Here was black's best chance to defeat white, and he missed it. Much better would be Rxf3! After Qxf3, Bg4! winning the Queen | 
   
    | 
|   | 
| 
 | 
23. Kh1 
 | 
This accomplish's nothing, after Rxf3 white still cannot recapture with his pawn because Qg2#! | 
   
    | 
|   | 
| 
 | 
23... Nf4 
 | 
Black once again misses his chance and offers a tradeoff which makes his Rf6 move even worse because now the rook will move again | 
   
    | 
|   | 
| 
 | 
24. Bxf4 Rxf4 25. gxh3 
 | 
Black's attack is gone, he has lost his chances on the queenside and kingside, his board will now quickly fall apart | 
   
    | 
|   | 
| 
 | 
25... Rxf3 
 | 
A useless sacrifice as the Bishop is no longer needed to defend g2 | 
   
    | 
|   | 
| 
 | 
26. Qxf3 Rf8 27. Qe2 Rf4 28. Qxe7 h6 29. Nxd6 Rf6 30. Rg1 
 | 
While both players made mistakes, his kingside attack would have not even had a possibility of working had white played correctly. Black lost this game because of one move. 4...Nf6?? The best lesson that can be learned from this game is; always study an opening before using it. Gameknot has an excellent databse available to all players, and it is not breaking any rules to view the database during a game, so use it if you are not sure what to play during the opening. |
