A game with mates (5)

I believe the answer is:

chess

(Other definitions for chess that I've seen before include "that has over thirty men on board" , "Sixteen-men-a-side game" , "This is played on board" , "Benny Andersson and Bjorn Ulvaeus musical" , "Ancient war game whose name may have derived for the Persian for 'king'" .)

I've seen this clue in The Guardian.
