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.

The episode centers around murders associated with moves on a chess board. Following the screen with Sidle and Sanders at the parking garage the scene then goes to the lab with the CSI techs analyzing evidence. The song playing is "Your Move" by Yes from 1971. The song alludes to the game of chess as a metaphor for relationships. Lyrics include the phrases "Take a straight and stronger course to the corner of your life. Make the white queen run so fast she hasn't got time to make you a wife. 'Cause it's time, it's time in time with your time and its news is captured for the queen to use. Move me to any black square." See more
