♟️ En Passant in Chess
🔹 What Does “En Passant” Mean?
En Passant (pronounced on pah-sahnt) is a French phrase that means “in passing.”
It’s a special pawn capture move in chess that can only happen immediately after a pawn moves two squares forward from its starting position.

🔹 The Rule Explained Simply
When a pawn moves two squares forward from its starting position (for example, from e2 to e4), it passes over a square where it could have been captured if it had only moved one square.
If there’s an opponent’s pawn on an adjacent file (next to it), that pawn can capture it “in passing” — as if it had moved only one square forward.
But here’s the key: 👉 The en passant capture must be done immediately on the next move.
If you don’t take it right away, the chance is lost forever.

🔹 Example
Let’s say:
White pawn is on e5.
Black pawn moves from d7 to d5 (two squares forward).
Now the black pawn has passed the d6 square — right next to the white pawn.
White can capture the black pawn en passant by moving:
> e5 × d6
White’s pawn moves diagonally to d6, and the black pawn on d5 is removed — even though it’s not on that square anymore.

🔹 Important Conditions
1. The capturing pawn must be on its fifth rank (for White, rank 5; for Black, rank 4).
2. The opponent’s pawn must make a two-square move from its starting position.
3. The capture must be done immediately on the next move.
4. You can only capture a pawn, not any other piece.

🔹 Why Does This Rule Exist?
Without this rule, a pawn could avoid being captured by skipping over a square where it should have been in danger.
So en passant was created to keep the game fair and logical, preserving the natural balance of pawn movement.

🔹 Example in Words
Imagine:
White: Pawn on e5
Black: Pawn moves d7 → d5
White says, “I can capture you in passing!”
Then moves e5 × d6, taking the pawn that just jumped past.

🔹 Fun Fact
The en passant rule was introduced in the 15th century, around the same time pawns were given the ability to move two squares forward from their starting position. It’s one of the few “historical” rules that still surprises new players today.
