Paul Motta has played many Blackmar-Diemer Gambits, and I published quite a few of them over the years in BDG WORLD. Today I was prowling through some old photos and came across this one.
Fortunately, there are some identifying notes on the back of the photo. It was taken at the Montana Open in Missoula, in May 1988. Paul has the white pieces, and his opponent is Bill Greer. A quick check in my database of 14 trillion BDGs turned up the game. The clock indicates it’s Black to move; but what is the move number?
