1. e4 
 | 
This game was played on the German chess site schacharena.de. It is interesting for a cross pin in the middle game. | 
   
    |

| 
 | 
1... d6 2. Bc4 
 | 
A bit unusual, the standard moves are d4 and Nc3 after black's Nf6. | 
   
    | 
|   | 
| 
 | 
2... Nf6 3. d3 
 | 
Still Nc3 could have been played here. | 
   
    | 
|   | 
| 
 | 
3... g6 4. Ne2 Bg7 5. O-O O-O 6. Bb3 Nc6 
 | 
Black develops the pieces further. | 
   
    | 
|   | 
| 
 | 
7. c4 
 | 
There are some weak dark squares in white's camp already: d4, b4. | 
   
    | 
|   | 
| 
 | 
7... a5 
 | 
Attack on the queen side. | 
   
    | 
|   | 
| 
 | 
8. Ba4 
 | 
White forgets to develop his pieces. | 
   
    | 
|   | 
| 
 | 
8... Nb4 9. a3 Na6 10. Re1 Bd7 
 | 
Attacks whites only active piece. | 
   
    |

11. Bxd7 Qxd7 12. Qd2 Nc5 
 |

Opens the b-line. | 
   
    |

Weakens one more dark square: e3. Now there are several dark diagonals in white's camp open for black to exploit. | 
   
    |

| 
 | 
14... bxc4 15. dxc4 Rfb8 
 | 
Black searches for inititative on the queen side. | 
   
    | 
|   | 
| 
 | 
16. Nf4 Nb3 17. Ra2 Qc6 
 | 
The queen enters the queen side action. | 
   
    | 
|   | 
| 
 | 
18. Qc2 Nxc1 19. Qxc1 Bh6 
 | 
Pins the knight to the queen. Here an exciting game takes its course! |

20. Nd5 
 | 
! If 20...Bxc1 then 21.Nxe7  and forks king and queen. | 
   
    | 
|   | 
| 
 | 
20... Qc5+ 
 | 
The queen goes on the dark diagonal towards the white king. |

A cross pin!! Normally this is lethal, but white finds here again and again a way to hold on. |

52... Rxd6 53. Kc4 
 | 
The rest was blitz, playing for the opponent to lose on time. But fortunately 2 min were enough for me to get the game into the safe mate-harbour. |
