Official Rule Breakdown

According to Article 3.7.d of the FIDE Laws of Chess, a pawn attacking a square crossed by an opponent’s pawn which has advanced two squares in one move from its original square may capture this opponent’s pawn as though the latter had been moved only one square. This specific capture is only legal on the move following this advance and is designated as an ‘en passant’ capture.

Step-by-Step

Step 1: An opponent moves a pawn two squares forward from its original position in a single move.
Step 2: The capturing player must perform the en passant move on their very next turn.
Step 3: The capturing pawn moves to the square the opponent's pawn 'skipped' over.
Step 4: The opponent's pawn is removed from the board as part of the capture.

Example Play Situation

Alice moves her white pawn from e2 to e4. On the next turn, Bob moves his black pawn from d7 to d5. Alice can then immediately perform an en passant capture by moving her pawn to d3 and removing Bob's pawn.

Common Misconceptions

Waiting several turns to perform en passant
