Subject: Depth In relation to strength

As everyone has heard before Computers are not GM's as they can't get the title
but they are at a minimum Master strength and not only in the rarest of
Positional Games which few Players out there will be able to pull off anyhow.
Remember Deep Blue 1 if you ignore the first game as being a tactical one and
try to figure out the performance of DB you get approximately 107points below
it's 2642 Rating for the match   2535. I am sure somebody will argue that DB is
alot stronger than this and that is fine but the point is is if a computer with
192 processors and some of the best programmers in the field (not counting who
knows how many bugs as it still did play well) only plays 2535 at best and 2588
as a rough average and compared to various commercial software
Deep Blue   how fast compared to 1ghz PIII??? 2642       2535   2588   14Ply
Deep Junior 8x 700 or about 4.130Ghz          2702       2594   2648   ?

As you can tell it is hard to compare available programs to ones that aren't
available. Also the Depth of search is different. This goes back to if Crafty
Shredder Ferret ETC searched 100Mnodes a sec will the depth be the same.
The answer is no, so my question is
1 at what Depth are various programs playing at GM strength
2 at which depth are they comparable to the Deep Blues ......
3 What Programs are best with Positional Play and is their play as good as deep
blue or better, if not what ply depth is needed.
