Hey lichess people, I found this thing playing against Stockfish (4):
e4 Nf6, e5 d5, exf6 e5 AND it doesn't allow me to take en passant the e5 pawn.
Is this a weird rule I'm not aware of? Or a bug?
Thanks!!
Just happened again...
Read the rules of chess, on wikipedia for example.
En passant only applies when your pawn is on the fifth rank.
It is helpful to think about the en passant rule in terms of chess history: in the early days of chess, pawns could only move one square, even on their first move. Later, when they chose to speed up the game by allowing pawns to move two squares on their first move, a seventh-rank pawn could move two squares and avoid capture by a pawn on the fifth rank. To avoid this unfairness, en passant was introduced, which meant that a pawn on the fifth rank could capture a seventh-rank pawn that had just moved two squares forward, as if the latter pawn had just moved one square.
When your pawn is on the sixth rank, the seventh-rank pawn can avoid capture simply by moving forward one square. Therefore en passant does not apply.
Thank you Chessatom fo the kind explanation, you're totally right, my bad. Thibault, you weren't helpful but thank you for replying.
