Here are some postal games played by an old version of Greenblatt's MacHack, which seemed to do better than the latter versions, because it had less evaluation and more brute force. The program is playing at fanout parameters of 15 first two plies, 9 all deeper plies. The minimum depth is 8 ply. Although the players are probably playing at no better than class C, OCM generates some interesting moves, particularly in the first game.
