This game shows you how International Master Hans Bohm suffers quick
defeat. |
|
1. e4 e5 2. Nf3 Nc6 3. Bb5
|
This opening is the Ruy Lopez which is most popular. |

|
|
|
3... a6
|
The most common move |

|
|
|
4. Bxc6
|
The Ruy Lopez exchange variation gives Black bad pawn structure but it
also gives Black a bishop matching pair but Black is also behind in
development. |

|
|
|
4... dxc6 5. O-O
|
White can also play 5. Nc3 or 5.c3 |

|
|
|
5... Bg4
|
The International Master Hans Bohm is known in Dutch chess circles as a
brilliant positional player. His very good handling of the Ruy Lopez
exchange variation has brought him a lot of victories, including a fine win
over the American chess giant Samuel Reshevsky in the main line 5.f6
6. d4 cxd4 7. Nxd4 c5 8. Nb3 Qxd1 9. Rxd1, where White's Kingside
pawn majority battles against Black's Bishop matching pair, that is why
his opponent avoided the main line. In the game Black hopes to stall the
d2-d4 central break. |

|
|
|
6. h3
|
! This type of move is known as "putting the question to the Bishop" Black
now faces a very hard decision. If he exchanges by 6. Bxf3 Qxf3 Black
then gives up the advantage of the Bishop matching pair and still has the
doubled c-pawns. If the Bishop retreats |

|
|
|
6... h5
|
! |

|
|
|
7. d3
|
If 7.hxg4?? hxg4 8. Nxe5 9. f4 g3! Which results in a fast checkmate
thanks to the open h-file. Such of these tactics are very important in
this variation of the Exchange Variation. |

|
|
|
7... Qf6
|
Adding pressure to the pin |

|
|
|
8. Be3 Ne7
|
If Black was to trade by 8.Bxf3 9. Qxf3 Qxf3 10. gxf3, doubling up White's
pawns then White will go for a 11.f4 break and to undouble the pawns
with an edge. But now Black wants to get his Knight on the g6 square
where it will control the f4 square. |

|
|
|
9. Nbd2 Ng6
|
As Black desired. |

|
|
|
10. hxg4
|
? Thanks to this game 10.Rel is now preferred. In that case White would
be ready, at last! to acually play 11. hxg4 hxg4 12. Nh2! Qh4 13. Nfd1!
blocking of the crucial h-file and winning a piece. |

|
|
|
10... hxg4 11. Ng5
|
Hans at this point was quite happy with his position. He has blocked off
Black's Queen from going to h4 while Black has blocked it from the h6
square. |

|
|
|
11... Nf4 12. Qxg4
|
With the g4 pawn gone, White can block a battery along the h-file with
Ng5-h3 when desired. Also, White is poised to do Bxf4 removing another
annoying attacker. But Hans overlooked...... |

|
|
|
12... Qxg5
|
!! This! Whoops! Hans was just so preoccupied with stopping a Queen
and Rook battery down the h-file that he missed the point that
13. Qxg5 Ne2 is both check AND Mate! |
