For the record, our most reliable version (prior to singular >extensions) was very 46e, which is what we used for playing about 50 games. I think that this reliable version did not play against deep thought so it is not clear that Cray blitz could not beat deep thought. <snipped> >Check out the following tournaments: > >1983 wccc event. 4 wins 1 draw.

I think that in these years Cray blitz was clearly slower then cray blitz of today and I am interested in the ability of cray blitz that can look at 7,000,000 nodes per second. <snipped> >>2)Crafty may have better positional understanding relative to cray blitz because >>you learned to change crafty from experience of many games in ICC when you had >>not the same experience with cray blitz. > >They are _very_ similar. Most of crafty's eval came from Cray Blitz, except >for things that I can't do due to them being too expensive on a non-vector >machine. Cray Blitz actually has a _bigger_ eval than Crafty, not smaller. The question is if it has better evaluation. I understand that you did in cray blitz things that you cannot do in crafty but I guess that you know today from your experience in ICC things that you did not know some years ago when you worked on cray blitz.
