Chester Jones was a criminal known also as Checkmate for his obsession with chess. After he escaped from the Dynamic Duo, he was poisoned with radiation and died. Before dying, he created an elaborate plan to kill Batman and Robin using fantastic deathtraps. His henchmen failed to avenge Checkmate and they were all eventually captured.
- This version of Checkmate, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
