Chess was played between two players using a square chequered board with 64 squares arranged in an eight-by-eight grid. At the start, each player (one controlling the white pieces, the other the black) controlled 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The object of the game was to checkmate the opponent's king, whereby the king was under immediate attack (in "check") but without a way to escape the attack on the next move.
Major General Seth Chernock of the Shilo Sector and Brigadier General Dennis Tresca of Hades played a longterm game of 'postal' chess -- one move per courier message. The absence of a new move in some message traffic made Chernock suspicious, and caused him to organize a relief expedition to Hades. He took a task group from Shilo to Hades to investigate; it was destroyed during the Battle of Cerberus. (HH8)
