King's Gambit En Passant in Chess

In the King’s Gambit, “King’s Gambit En Passant” refers to the tactical possibility of capturing a pawn en passant after it advances two squares, creating an immediate opening or tempo gain. The defining feature is that White’s early pawn play (typically from the King’s Gambit structure) allows Black to push a pawn two squares into a square that can be captured en passant on the very next move.
