En Passant Rule in Chess (Explained & Examples)

The en passant rule often sparks curiosity and confusion in chess.

In chess, “en passant” is a special pawn capture that occurs when a pawn moves two squares forward from its starting position and lands beside an opponent’s pawn, which can then capture it as if it had moved only one square forward.

The en passant rule was introduced in chess to prevent pawns from evading capture by moving two squares forward, ensuring fair play and game balance. In the early stages of chess, pawns could only move 1 square forward on their first move, unlike the two we have today.

Below we look deeper into the en passant rule, its history, how it works, and its strategic implications.

The History of the En Passant Rule

The en passant rule, which is French for “in passing,” was introduced in the 15th century as a way to prevent players from avoiding capture by advancing two squares on their first move.

This rule was added to address a specific situation that arose due to the initial double-step move allowed to pawns.

Before the en passant rule was established, pawns could move one square forward on their first move.

This created a scenario where an opponent’s pawn could bypass being captured by simply moving two squares forward.

To rectify this, the en passant rule was introduced, ensuring fair play and maintaining the balance of the game.

How Does the En Passant Rule Work?

The en passant rule applies only to pawns and occurs when a pawn moves two squares forward from its starting position.

If an opponent’s pawn could have captured the pawn had it only moved one square forward, the opponent has the option to capture the pawn “en passant” on their next move.

To execute the en passant capture, the capturing pawn moves diagonally to the square where the opponent’s pawn would have landed if it had only moved one square forward.

The captured pawn is then removed from the board as if it had been captured traditionally.

It is important to note that the en passant capture must be made on the very next move. If the opportunity is missed, the chance to capture en passant is lost.

Examples of the En Passant Rule

Let’s explore a couple of examples to illustrate how the en passant rule works:

Example #1

In this case, black moves its pawn two squares forward to f5.

White can capture behind to f4.

The position looks as so after the capture.

Example #2

Here the c7 pawn is under attack by the bishop and there’s no realistic way to save it with another piece, so it moves.

By moving two squares, that puts the immediate decision on white to use its next move to take it en passant.

It only moving it one square, that gives white the optionality to do it on subsequent moves beyond just the next one.

Example #3

Here, white captures en passant in the context of the Sicilian, O’Kelley, Yerevan System.

Strategic Implications of the En Passant Rule

The en passant rule has significant strategic implications in the game of chess.

Understanding and utilizing this rule effectively can give players an advantage and influence their decision-making process.

Here are a few key strategic implications of the en passant rule:

• Timing: The en passant capture must be made on the very next move. This means that players need to be aware of the potential for en passant captures and plan their moves accordingly.
• Pawn Structure: The en passant rule can impact pawn structure. A player may choose to move their pawn two squares forward to create an opportunity for an en passant capture, potentially disrupting their opponent’s pawn structure.
• Opening Strategies: The en passant rule can influence opening strategies. Players may choose to avoid moving pawns two squares forward to prevent potential en passant captures or use it as a tactical maneuver to gain an advantage.
• Material Advantage: The en passant rule can lead to material advantages for the capturing player. By capturing en passant, a player can remove an opponent’s pawn without losing their own, potentially altering the balance of power on the board.
