I know DT could be searching 10Ply find a >move but a regular Fritz might take 20+ ply I also know that Deeper blue could not see Qe3 in the second game against kasparov when top programs can find this move after enough time. I also know that Deep thought blundered against Fritz3 when all the programs of today have no practical problem to avoid the tactical mistake. If you are selective by choosing your moves you can prove everything. I am guessing that CB is closer to >the Deep's than your average program ...

I strongly believe that they were not doctored otherwise they could give better picture for Deeper blue. The picture that I see for Deeper blue is not good. Deeper blue never saw Qe3 in the pv. In some cases top programs can find similiar pv's and they need smaller depthes to do it(I only looked at the first plies of the pv because I do not trust the last plies). Uri
