The games are very bad. It plays ugly moves. See ICCA report journal june 1997, with all the ugly moves it plays. On average 5 bad moves a game. Additional it's an utmost passive program. None of todays programs is passive. Further may i remind you it just searched 10-12 ply. See the logfiles. Important moves just out of book it reached 10 plies. Now it might have gotten 12.x on average of course, but that's nowhere near todays 'average' search depth. My average is about 18 ply, thanks to the big depths in endgame.
