I copied this game from one of my chess books ... It 's a short game with a valuable lesson.   | 
| 
 | 
1. f4 
 | 
Bird' s opening | 
   
    | 
|   | 
| 
 | 
1... d5 2. e3 c5 3. b3 
 | 
White's bishop must develop on the b2 square otherwise it might be jammed | 
   
    | 
|   | 
| 
 | 
3... e6 4. Bb2 Nf6 5. Nf3 Be7 6. Bd3 
 | 
When both the bishops are aligned like this they become extremely deadly | 
   
    | 
|   | 
| 
 | 
6... O-O 7. Ng5 
 | 
the h7 pawn is in danger | 
   
    | 
|   | 
| 
 | 
7... g6 8. h4 
 | 
Bringing the pawns up in front ensure blacks doom  | 
   
    | 
|   | 
| 
 | 
8... Nh5 
 | 
This not only stops the pawn development but also allows an exchange between the knight and the bishop but it is still a bad move ..... | 
   
    | 
|   | 
| 
 | 
9. Qxh5 
 | 
Qxh5! Brilliant 
if gxh5 then Bxh7   
So as black cannot kill the queen
and the Qxh7   another mate
Black is forced to kill the knight | 
   
    | 
|   | 
| 
 | 
9... Bxg5 10. Qxh7+ 
 | 
Qxh7 
Blacks game is falling right down on him | 
   
    | 
|   | 
| 
 | 
10... Kxh7 11. hxg5+ Kg8 12. Rh8# 
 | 
And a beautiful short game |
