Thursday's game at the local chess club paired me against a quickly improving player who had won the club's Player of the Year award with his recent winning record. Unfortunately for me, he had recently lost a game to the Blackmar-Diemer Gambit and had spent time looking at the opening.
I had recently added the BDG to my repertoire to replace the Veresov Attack, which I thought was too passive. I knew some of the lines, but obviously not enough of them. However, when Black responded with 1...d5, I decided to try out the BDG.
I resigned early when I could not find a plan that held any promise, whereas I could see a good plan for Black. I thought that I was behind approximately 2.5 pawns. A subsequent computer analysis of the final position is interesting:
-1.12 Rybka 2.3.2
-1.55 Toga II
-2.08 Fritz 12
-2.27 Phalanx XXII
-2.38 Shredder 11
Lesson learned: Study ALL the main lines of an opening before playing it in rated competition.
P.S. A while back, I posted that my practice games against the computer were going to be played on a real board and the moves then transferred to the computer. Since then, I have been able to increase the computer engine's strength by 200 rating points and I am doing better against the silicon monster. It slows down my playing and makes for better analysis of each move.
