Very interesting Uri!

But how did you make that Fritz move when it is on depth4 or 5 ??
I believe that many of this games (at depth 3,4,or5) take only a few seconds.
Is this right?

If the program using a 8x procesor machine against Kramnink, see one ply more
than the normal fast machine, how strong will be ?? in elo??
