For question 1, do the math as follows...  Cray Blitz on a T932 does about
7M nodes per second in the middlegame.  Most programs are going to be about
1/10th that speed at best on a athlon 700.  Doesn't bode well for the athlon
at all, yet.

The comparison between crafty and CB is hard.  Crafty now has some endgame
code that CB didn't have (the recent majority/split passed pawn code, etc.)
But CB had some king-safety stuff that crafty doesn't (pieces attacking squares
arount the king, pieces attacking from behind other pieces, etc.  So it is hard
to say.  Crafty on a good alpha would be just as fast as Cray Blitz, and (I
believe) might be a bit better overall now, even though Cray Blitz would be
better tactically because it had the full singular extension (FH and PV)
code working plus the other selective things we did.

It would be interesting but nearly impossible to play games to find out, as
getting a dedicated T932 is essentially impossible...
