Bird Opening Wagner Zwitersch Gambit Skewer in Chess

The bird opening wagner zwitersch gambit skewer is a tactical motif arising from the Bird Opening line associated with Wagner and Zwitersch, where White sacrifices material to open lines and then uses a skewer to win a more valuable piece. The defining feature is that a forward-driving piece (often from the kingside/center after the gambit) lines up an enemy piece so that it cannot move without exposing something behind it.
