The rules of chess can be quite particular — each type of piece has a specific movement and game setup, for example — but so can the language and the etiquette. In most OTB (over the board, or in-person) chess tournaments, the touch-move rule is in effect, meaning if a player touches a piece, they must play it. But there’s a little loophole for this rule: the French loanword “j’adoube,” which literally translates to “I adjust.” If a player wants to slightly adjust a skewed chess piece, they can first say “j’adoube,” and they aren’t subject to the touch-move rule.
