Bishop blindness

A mental disorder common among non-professional chess players causing them to not notice the opponent's bishops when making a move.

— white: (moves his queen next to the opponent's king) checkmate!
— black: Nuh-uh (captures the queen with a bishop 8.23 megaparsec away)
— white: Goddamit! I have a bishop blindness!
