The Lasker Trap is a chess opening trap in the Albin Countergambit, named after the second World Champion Emanuel Lasker.
Black plays the Albin-countergambit to face White’s queen’s gambit. The unusual though very powerful feature of Lasker Trap is the rare underpromotion to a knight on seventh move.
It is a good idea to use this opening in quick games since it is not very often played and your opponent most likely would be unprepared for it.
