Blackmar-Diemer Rasmussen vs Wight

David Wight asked, “Would you have any Ernst Rasmussen games to post? I have one game that I was black against Ernst and beat his BDG.” I answered, “Yes David, I have several of his games. I will look for one. If you have any of your games that you would like me to post, send them to me.”

It seems that I did not immediately have to look for a game by Ernst Rasmussen after all. Below is the game that David Wight sent me. Ernst Rasmussen was one of the top BDG players in his prime decades ago when his rating was over 2000. Here we have a popular line in the Blackmar-Diemer Gambit Declined. The moves 4.f4 Bf5 lead to the BDG Vienna Defence. Rather than grab another pawn on f3 Black chooses to hold e4 for the moment. White could develop a bishop at this point. White has two options. First is 5.g4 Bg6 with either 6.h4 or 6.g5. Second is Rasmussen’s choice 5.fxe4. Black played a common defense 7…Qc8. The battle was balanced until White blundered.
