  1. (chess) A chess game starting from the initial position which results in a particular position appearing on the board, associated with retrograde analysis problems.
    • 1999, Burt Hochberg, Chess Braintwisters‎[1], New York, N.Y.: Sterling Publishing Co, Inc., →ISBN, page 30:
      In this and the next problem, don't be concerned that the moves make absolutely no sense in the normal way. These are similar to what problemists call "shortest proof games" (SPGs). The object of an SPG is not to checkmate the opponent but to reach a given configuration in the fewest moves from the opening position. In this problem, a "proof game" (PG), the object is somewhat different, since the final position is not given but is for you to discover.
    • 2004 March 31, Joost de Heer, “Software for retro-analysis?”, in rec.games.chess.computer‎[2] (Usenet):
      Natch (and Euclide: http://lestourtereaux.free.fr/euclide/index.html) are programs for proofgames, not for classical 'last n moves?' retro compositions.
  2. Used other than figuratively or idiomatically: see proof,‎ game.
