Here's a nice trap I set in a 3 minute game:
White played to win the a pawn with 1.Bxc6
Rather than play the natural (and better?) recapture, 1. ...Qxc6, I chose 1. ... bxc6 with a nice trap in mind.
The idea was 2.Rxa7 c5!?
Here white must try 3.Rd5 or 3.Ba5, leaving his pieces a bit tangled.
Instead, my opponent played 3.Ba3, falling right in.
Black To Move
3. ... Qb6!
4.Ra4 (4.Bxc5 was better, lessening the damages.)
4. ... Qb3! (making use of the awkard rook on d1)
Black wins a rook!
Here is the complete game:
