No! The Machine Didn't Make A Draw Claim, By Repitition!!

If you don't understand what I mean, why argue?

Not the same thing, and I don't think it wise to elevate machines over man!

Well on second thought, maybe the machine in this case anyways, should be
listened to!

But for practical reasons it should be no more than 75-100 moves for a human
unless otherwise stated.

Computers which "know" book wins should be allowed to use them, no limit!
