pls let me know what you think.

Lets say, I take these measures to perform a "more accurate" match between these
2 programs, under these conditions.

 I let both programs play under fritz interface,

with ponder=off

(but the game will be on tournament time control 80'/40+60'/20+30, so even if
crafty plays with ponder=off it wont suffer. Because I AFAI remember the problem
with crafty ponder=off was with its time allocation.)

with 2600.ctg

(but I will observe all the games to see if any programs come out of book with a
- score, if any programs comes out of book with more than lets say -.50 score, I
wil discontinue the game.)

And of course I will try to remember to quote "Under these circumstances", when
I post the games next time :)
