En passant in chess in terms of queue jumping
En passant is essentially the chess equivalent of a middle-aged man in a beige mac aggressively shoving his way to the front of a Post Office queue because someone else dared to skip a square.
The rules are quite specific, designed to stop your opponent from pulling a fast one during their initial sprint. If your enemy pawn advances two squares from their starting rank to land directly beside your own, they are technically trying to bypass your line of sight. You are then allowed to capture them as if they had only moved one square forward, providing you exercise this right immediately. It is the board game version of a security guard tapping you on the shoulder to remind you that your attempt to bypass the check-out aisle is, quite frankly, a bit desperate.
You have exactly one turn to rectify this breach of social etiquette before the moment passes, much like the window of opportunity to tut loudly at someone cutting in at a motorway slip road. If you wait until the next move, the offender has effectively settled into their new position and become a permanent, annoying fixture of the board. It is the only time in chess where you can legally snatch a piece that is not actually occupying the square you are attacking, making it the most confusing rule since the introduction of the self-checkout machine in Tesco.
Where the analogy breaks downChess pieces do not actually feel the simmering, repressed British rage that fuels a genuine queue jumper.
