Middle English: from exchequer. The original sense ‘chessboard’ gave rise to chequered meaning ‘marked like a chessboard’; hence the sense ‘pattern of squares’ (early 16th century).
etymonline
checkered (adj.)
late 14c., "marked with squares or checks," past-participle adjective from checker (v.). Checkered past (1831) is from a figurative use: "variegated with different qualities or events, having a character both good and bad."
