A chess game was being played on the computer at the Divine Doll Company factory in Pigeon, Utah, when Mark, Demetri and Sheriff Keegan entered the building. The man playing the game managed to escape, killing Keegan, but leaving the white queen chess piece and a cell phone behind.
The first game
Each turn of the game was shown on the computer, although the last move was listed in a panel at the side of the screen, and not yet displayed on the board on the screen. After the last move shown, White will allegedly lose the game within two moves. ("White to Play")
In "A561984" we see a flashback of D. Gibbons while Janis lays out the facts the FBI has about the man to Simon. Interestingly, the game of chess we see in the flashback is not as far advanced as the game seen in "White to Play". We see the game after 22 moves, black has just made the Nxe5 move.
- First character is the piece (K for King; N for Knight; P is omitted)
- If second character is an x, a capture occurred
- Second character (or third if second is an x) is the lateral destination (The board is lettered "a" through "h" left to right from White's perspective
- Third character (or fourth if second is an x) is the vertical destination (The board is lettered "1" through "8" top to bottom from White's perspective
- O-O is a castle move
The second game
The same game as in "White to Play" is played between Frank Poole and Hal9000 in the film 2001: A Space Oddysey. The real historical game is Roesch vs Schlage, 1910.
