I decided to annotate this game because it shows that a chess player must be cocentrated in every moment of the game and because I won after only 19 moves - something which is not usual for me.  |

1. e4 c5 
 | 
I tried diffrent variations against e4 but nothing has proven to be better than sicilian. |

2. c4 
 | 
White pushed the game into Gloria variation. I've rarely met this variation so I decided to follow the book strictky or at least as far as I could. |

2... Nc6 3. Nc3 g6 4. d3 Bg7 5. Bg5 
 | 
Until this move everything was usual. I don't know what the idea of ths move was but it didn't existed in the DB. I decided to castle early, because as I said I haven't played the Gloria variation so often. |

5... Nf6 6. Bxf6 
 | 
Well if Bg5 wasn't a complete mistake so that is a blunder. Why would you possibly play that ? Can someone answer me ? You lose a turn to bring your bishop ahead and then exchange it for a undeveloped knight. Additionaly he allows my black squared bishop to open his diagonal and threaten c3 and put pressure on b2 and a1 |

This move is obviously a mistake. He wants to have the possibility of Bc7 but doesn't see that Bxb2 |

Of course I don't retreat immediately. White's mistakes give me a oppurtunity to attack the uncastled king. |

Only possible move if he wants to castle in the future. |

10... Bd4

I retreat but not fully. My bishop is still in a good position, but White's chances to castle and put an end to my attack are big. |

Another mistake. I don't have an idea what's the purpose of this move. He opens my black squared and makes his castling very complicated.  |

I eliminate the danger of Bc7 i order to make my attack easier. |

I win another pawn. |

13. Ne2 
 | 
Well that is another move I don't like. He leaves the pawn on d3 without any support and tries without having enough power to force my bishop to retreat. | 
   
    |

| 
 | 
13... Be3 
 | 
As I said - not enough support |

14. Nb3 Nb4

I involve my kight in the attack in order to have more power and to push him for Bc7# |

I decide that is it time to attack and force the king to move from his hide place |

16. Kf2 Nxd3+ 
 | 
The unsupported d3 pawn helps me to continue my attack and bring the king further away. |

17. Kg3 
 | 
only possible move because of Be3# |

17... h5 
 | 
Here I need to bring another figure in the attack and the h7 pawn is ideal for it. |

White's last mistake. Not so bad as a move but only when the king isn't near mate. I mean the knight does nothing to help the king of escaping the dangoures situation. A possibly better move is h4 which would at least give the king a chance to survive. |
