BDG Surprise by John Crompton

John Crompton sent me a link to a Blackmar-Diemer Gambit game that he won in a 2010 tournament. Tom Purser analyzed this game at the time in his blog. Purser does not write on chess anymore, but we are glad for his encouragement and support.

Crompton told me that this "was the first time I played in a tournament in a long time." John added, "Tim, I must say that that game caught some there at the tournament by surprise." Yes, the BDG does that. When a player plays a bold gambit in a live tournament, people expect someone to go down in flames and quickly. They flock in anticipation to watch them burn.

For this post I decided to annotate the game with fresh eyes rather than just quote Purser (although Tom is a great writer to quote). I found the game in my database and examined it in some detail. The move 6.Bc4!? is the best alternative to 6.h3! Tom Purser noted that Crompton played "the Blackmar-Diemer, against an opponent who had recently won the state senior's championship." That was former USCF Expert Charles Reeve.

I have other 6.Bc4 games in section 5.0 of my Blackmar-Diemer Games 1.
