The Conditions for En Passant:

For En Passant to be permissible, the following three conditions must be met:

• Adjacent pawns: The pawn making the move must be on its fifth rank.
• Enemy pawn’s initial double move: The opponent’s pawn must move two squares forward from its starting position, landing beside the player’s pawn.
• Immediate response: The capturing pawn must make its move immediately after the opponent’s double pawn advance.

Execution of En Passant:

Understanding the Mechanics:

To fully grasp En Passant, consider the following scenario: Suppose White’s pawn is on its starting square (e.g., e2), and Black’s pawn on the adjacent file (e.g., d7) moves two squares forward to d5.

In this situation, White’s pawn can capture Black’s pawn en passant, as if it had only moved one square to d6. This capture happens immediately after Black’s pawn advances to d5, and it is mandatory. In other words, the White player cannot choose to ignore it.

Historical Context

In the early forms of chess, such as Chaturanga and Shatranj (predecessors to the modern game), the En Passant rule didn’t exist. These ancient versions of the game lacked many complexities that modern chess has, including En Passant.

The rule is commonly attributed to Pedro Damiano, an Italian chess player and theorist. He documented the rule in one of his books about learning to play chess in 1512. His inclusion of the En Passant move marked a significant development in chess strategy. It also introduced a new dimension of tactical play.

Over the centuries, En Passant became an established part of chess. It was integrated into the rules of play and shaped the strategies employed by players. As chess literature proliferated and the game gained popularity across continents, En Passant gained recognition as a fundamental aspect of chess strategy.

As chess evolved, En Passant found its place among the official regulations governing the game. It became a part of various editions of the official rules, including the widely recognized FIDE Laws of Chess.
