Chess opening:
Alekhine's defence (B03), four pawns attack, Korchnoi variation
|
The year is 1973. The location is Petropolis, Brazil. The event is the FIDE Interzonal. A field of Super- GM's get together to battle for the right to be the next challenger for the World Championship. Ljubojevic (#3 in the world) is leading the field going into this 11th (and final) round match. Bronstein, with the white pieces, conducts a brilliant attack that defeats Ljubo and takes him out of the running for the title. I hope you enjoy:) |
|
1. e4 Nf6
|
Alekhine's Defense. |

|
|
|
2. e5 Nd5 3. d4 d6
|
Standard play so far. This move aims to undermine white's strong pawn presence in the center. |

|
|
|
4. c4
|
!? Ljubojevic is a leading expert of the Alekhine (from both sides) and 4.c4 is his "pet line". To play it against him shows a lot of nerve by Bronstein. |

|
|
|
4... Nb6 5. f4
|
! The Four Pawns Attack. |

|
|
|
5... dxe5 6. fxe5 c5
|
The Ljubojevic Variation of the Alekhine. Black is very comfortable in this position, and threatens to start ripping up the center. |

|
|
|
7. d5
|
Preserving central strength, but advancing dangerously fast without sufficient development to support. |

|
|
|
7... e6 8. Nc3 exd5 9. cxd5 c4
|
And both sides seem to have accomplished their goals. White has good space in the middle and will support with developing moves. Black owns the queenside and has numerous developing and attacking options. |

|
|
|
10. Nf3 Bg4 11. Qd4
|
! Hitting the c pawn and the Bg4. |

|
|
|
11... Bxf3
|
!? Black strikes with the aim of weakening white's kingside. While sometimes controversial to trade a bishop for a knight, notice that black is attempting to get white to castle queenside (putting his king on a half open file). |

|
|
|
12. gxf3 Bb4
|
Developing with a nasty pin. |

|
|
|
13. Bxc4
|
White starts gaining material. |

|
|
|
13... O-O
|
Considered strong, but my belief is that 13...NxB 14.QxN 0-0 is just as good for white. It would at least remove the pesky bishop on c4. |

|
|
|
14. Rg1 g6 15. Bg5
|
!! White exerts his dominance of the dark squares around the enemy king while developing with tempo. Very strong. |

|
|
|
15... Qc7 16. Bb3
|
!! Bronstein also wants the light squares, so he preserves his light squared bishop. Surely he saw......... |

|
|
|
16... Bc5
|
! To save his queen white must sac a rook! |

|
|
|
17. Qf4 Bxg1 18. d6
|
Advancing, attacking, and opening the diagonal for his light squared bishop. |

|
|
|
18... Qc8
|
And now for a quick evaluation.........black is up almost a full rook, but is underdeveloped. He should start getting his pieces moving quickly to maintain his material advantage. White is down almost a full rook, but his pieces are developed and he has momentum. Time for white to start pressing his initiative! |

|
|
|
19. Ke2
|
?! Not wanting to castle into a pin, Bronstein activates his Ra1 in a much more dangerous fashion, as his king is now dangerously exposed. |

|
|
|
19... Bc5
|
Preserving his material advantage, but not really accomplishing much else. |

|
|
|
20. Ne4
|
This aggressive move by white tells his opponent that he demands the right to control the flow of the next several moves. |
