When Tom Purser passed away, I was reminded of how much he enjoyed playing the Elephant Gambit. This opening as Black has some of the same characteristics that the Blackmar-Diemer Gambit has as White. His original book on the Elephant Gambit book was published on July 3, 1988 by Blackmar Press. The authors who compiled this book were Niels J. Jensen, Tom Purser, and Rasmus Pape.
Tom Purser played in an Atlanta tournament in 1983. There Tom won an Elephant Gambit vs “A. Sheehan”. The USCF lists a player from Georgia named Andrew Sheehan. I am guessing that he may have been Tom Purser’s opponent here. I provide my own detailed analysis of this line.
