The Englund Gambit Trap
The queen raid on b2 sets up a pin and mate on c1.
Opening: Englund Gambit. Set by Black. Level: Intermediate.

It only works after a mistake
White must play Bc3 for it to work. The Englund Gambit is unsound. Against correct play White keeps an extra pawn.
How to avoid it
Nc3 (instead of Bc3) keeps everything protected.
