Introduction

If you’ve ever seen a pawn disappear from the board without landing directly in front of the capturing piece, you’re not alone. You likely witnessed a rule many beginners don’t learn until much later: en passant.

Despite being a part of the official FIDE Laws of Chess, en passant is one of the most misunderstood rules in the game. It confuses beginners, surprises intermediate players, and even stuns spectators when seen in high-level tournaments.

In this article, we’ll break it down with clear explanations, simple diagrams, and real game examples so you’ll never be confused by en passant again.

 

What Is En Passant in Chess?

En passant, French for “in passing,” is a special pawn capture that only occurs under very specific conditions.

Here’s when you can use en passant:

    • The opposing pawn moves two squares forward from its starting position.

    • It lands right next to your pawn, which must be on its 5th rank (White) or 4th rank (Black).

    • You may capture the pawn as if it had moved only one square forward.

    • The capture must be made on the very next move. If not, the chance is gone.

This move can only be executed by a pawn, and it’s one of the only instances in chess where a piece captures without ending up directly on the captured piece’s square.

 

Why Does En Passant Exist?

When pawns were first allowed to move two squares forward on their initial move (in the 15th century), players realized that pawns could escape capture by bypassing squares controlled by enemy pawns.

To restore balance and fairness, the en passant rule was introduced. It allows the player to capture a pawn that would’ve otherwise been captured if it had advanced only one square.

 

How En Passant Works

Let’s walk through a basic example:

Position:

    • White pawn on e5

    • Black plays d7 to d5

White now has the right to capture en passant by playing e5xd6


White captures the black pawn en passant: e5xd6

After the move, the black pawn on d5 is removed, and the white pawn sits on d6—just as if Black had only played d7 to d6.

Important En Passant Rules to Remember

    • Only pawns can perform or be captured via en passant.

    • The right to capture en passant expires after one move.

    • The capturing pawn must be on the correct rank:

       

        • 5th for White

        • 4th for Black

    • The capture happens diagonally, just like a normal pawn capture—but onto an empty square.

Common Misconceptions About En Passant

    • “I can use en passant several moves later.” – False

    • “It applies to rooks and other pieces too.” – False

    • “It’s a glitch in online chess.” – False

    • “It’s mandatory.” – False (It’s optional)

When Is En Passant Useful?

While rare, en passant is not just a novelty. It can have important strategic implications:

    • Break central control of the opponent.

    • Open files for your rooks or queen.

    • Disrupt pawn structure in the endgame.

    • Gain tempo and restrict your opponent’s development.

En Passant in Famous Games

Even world-class players have used en passant as a tactical weapon or strategic opportunity in high-stakes matches. Here are some memorable examples:

1. Magnus Carlsen vs. Levon Aronian – Linares, 2009

Magnus Carlsen used en passant (e5xd6) to dismantle Aronian’s central pawn chain, taking the initiative and simplifying the position into a favorable middlegame.

2. Garry Kasparov vs. Nigel Short – London, 1993

Kasparov declined an en passant opportunity, choosing a deeper positional approach. The missed en passant became a case study in judgment over rules.

3. Hikaru Nakamura vs. Wesley So – U.S. Blitz Championship, 2016

Nakamura’s en passant capture in a blitz game turned the tide instantly, opening a file for a decisive kingside attack.

4. Alireza Firouzja vs. Nihal Sarin – Online Blitz, 2020

Firouzja baited Sarin into a two-square pawn push, only to respond with en passant—exposing his king and forcing resignation.

These games remind us that en passant is not just legal—it can be lethal when timed correctly.
