In the scene where Thurman and Santa are playing checkers (46:15) you can see 4 red checkers in the right corner of Santa's side of the board. When cut to Thurman, one of the red checkers is missing giving Thurman more than one avenue to be 'kinged' In each cut to the other character the red checker comes and goes. This continues to the point where Santa flings the checkerboard into the air.
