According to the Guardian the boxing promoter Don King manages a fighter known as Kali "Checkmate" Meehan. Checkmate comes from the Persian Shah mat meaning King is dead. I am sure Mr King, who is a keen etymologist, delights in the suicidal connotations of his pugilist's nickname.
Incidentally, a nickname is a metanalysis from an ekename meaning an extra name, in the same way that an apron was originally a napron.
Someday I shall do a long and extraordinarily dull post on every word that derives from chess (even cheque does).
