Blackmar Diemer Trap Normand

Nicolas Normand played the Blackmar-Diemer Gambit Vienna Variation. His game illustrates a point of theory that I have tended to overlook. This game gives me a good opportunity to examine it. Normand wrote to me. I quote a portion of his comments:

“Mr Sawyer, I am a 40-year-old French chess player. I have been playing chess since I am 15 but in chess tournament for only 3 years. I am a Blackmar-Diemer Gambit player as white especially Ryder gambit. I was wondering if you could give some piece of advice to find the best resources of information to fasten my studying. Of course, I tend to be a fan of Emil J. Diemer, Bill Wall's and Tom Purser's works and games. Maybe we could share some games. I thank you in advance. Nicolas
“PS: I have already most of your books that I enjoy a lot! I am very flattered that one of my games can be usable or even interesting. I have been following your different BDG chess works for a few years and you are a true reference for me (as German language is a bit harder for me, so sorry Emil !).”

Nicolas Normand as "DEATHSTAR81" wins a piece when Black falls into his trap.
