Indian Defense En Passant in Chess

In the Indian Defense, “En Passant” is a tactical pawn capture that becomes available only immediately after an opponent advances a pawn two squares past your pawn. The defining feature is the pawn placement typical of Indian structures (often with a pawn on d5 or e5 facing an adjacent pawn) that allows the en-passant capture on the next move. If the timing is missed, the right to capture en passant disappears.
