14 Analysis of the Machine Chess Game, J.Scott (White), ICL-1900 versus R. D. Greenblatt, PDP-10 I. J. Good

Virginia Polytechnic Institute It is no disgrace for Scott's program to have lost to Greenblatt's which seems to be the best chess program so far written: it finished one of its games with a brilliant five-move combination.* Judging by the present game Greenblatt's program could play about board 2000 for England. Neither program seems able to form a plan that is naturally expressed-by a description rather than by evaluation functions plus analysis. In the following game the first four moves on each side were played before the machines took over the play, because the ICI, program cannot castle. The move time limits originally agreed were 90 seconds for # xEss and'blitz speed' (5 or 10 seconds per move) for the Greenblatt program, as it was considered that the P-K5, and the game has the character of a French defence difficult to evaluate.
