En Passant Puzzle (Rated 1476): Win with En Passant — Endgame Tactic
This chess endgame puzzle highlights a rare but powerful tactical idea: using en passant to change the pawn structure at exactly the right moment. In classical chess, endgames often hinge on pawn races, passed pawns, and rook activity, so a single tempo can decide everything. Here, the key is to recognize that the trigger move creates a tactical window where a pawn capture is not just legal, but strategically decisive because it opens lines and removes a defender.
