Someone once took my Rook en passant. I was about eleven at the time, quite new to chess, and I'd not heard of en passant before. My opponent, also about eleven, explained: "there's some rule called 'en passant' which means that pawns can sometimes capture funny. I think it means I can take your Rook here".
I can picture either Calvin or Hobbes explaining that to the other . . .
Good lord, that's what this was about? A full page ad accusing and naming someone as a cheater, and branding chess.com as being soft on cheaters, and it all arose from not even knowing the rules of the game?
