Gifted former chess-player Greg soon realizes seemingly unrelated murders refer, by means and position, to chess pieces and moves. That applies also to previous murders in cities where Jenny Carroll's traveling chess demonstration tournament, presently in Vegas, came before. Greg's former mentor points out the serial killer has been repeating the moves of tournament star Karl Schrute against once national champion Troy Parker, who left public life after that very humiliating defeat. Ex-con chess-obsessed Troy-fan Lee Crosby not only has an alibi, the next murders and diverting moves require rethinking the plot. Written by KGF Vissers

Did You Know?


Guest star Ron Glass's role in this episode is somewhat reversed from his role in in the cult television show "Firefly". In "Firefly", he played a wandering priest (referred to as Shephards in the show), who implied that he walked away from a life as a government-sanctioned assassin. In this episode, he plays a chess master/mentor on a chess tour who is accused of being a serial killer, killing people in different cities/locations based on the moves in a famous chess match.

When Greg explains the queen-side castling to Sara he says (as with the animation): "Now there is a chess move known as castling, in which the player moves two pieces at the same time: the rook from its original position to D1 and the King from E1 to C1." However the official chess rule states that one should first move the King 2 places then the rook, this to avoid confusion with a normal move of the rook. See more »
