time: 6:58:23 AM >Rated time: 1:23:20 = 5000 Seconds Thanks Dann, for your effort! Possibly my game could be added to a Test Suite; As your demonstration proves it is tough, even for modern hardware and software. I was surprised that a Trogan Sac, like Bxh7+ would be so tough for machines to solve! I agree with you that there were attractive alternatives, like Qe4 and to some degree Qh5, which make it hard for machines to finally settle on Bxh7+! However, IMO, I think due to these factors it actually makes it a good test move for todays computers. Congratulations to Pro Deo, (Ed Schroder) and Glaurung! I'm sorry I don't know the name of the author of the latter program. Regards, Terry A. McCracken
