I wouldn’t harp too hard on that. When you play Chess with someone, you’re being competitive. You also know perfectly well that knocking over the board is not sportsmanlike (“sportsfighterlike”?).

Same thing here; I can play competitively and to the hilt and still understand that using the X-card (or a similar tool) for advantage in the game is totally out of bounds.

Any person who plays competitive games has mastered that kind of distinction since they were 8-10 years old; they’re impossible to play otherwise.
