The Elephant Gambit is a favorite among enterprising players who want to threaten White early in the game. This old chess opening was formerly called the Queen Pawn Countergambit. I played this gambit as Black in postal chess games in 1988 or 1989 with mixed success. Players I think of with the Elephant Gambit include Emil J. Diemer, Tom Purser, Jonathan Rogers, and Philip Corbin. With this chess opening the gambit player accepts some risk to activate all or most of the Black pieces for an attack. The game ends suddenly in this Elephant Gambit blitz game between Alvaro Donatti of Uruguay and Pavel Skatchkov of Russia.
