You can lose a chess match if you show too much cleavage

Talk about sexism! In the official rulebook of chess, a player playing against a woman may complain that she is showing too much cleavage. If the judges rule in the complainer’s favor, the woman may be disqualified from the match, forfeiting to the other player. This ruling would be an odd offshoot of the rule that players may not distract one another. This is a rule that many current chess players think should be taken out of the rulebook.
