I understand your point, and I have thought a lot about it. :) Another Shredder 7.04 observation: With Shredder 7.04 game analysis, in some opening positions (relatively closed I think) the eval score (even when given 512MB HT and minimum of 6 minutes, or up to 15 minutes per move) jumps up and down a lot between successive Black & White moves, even when the recommended move was played. This occurs under the Fritz 6 GUI, and the Shredder 7 Chessbase and Shredder 7 Classic GUIs. So it appears to not be the problem of a single GUI, but likely an Engine 'problem'. I guess this is possibly due to: 1) Heavy pruning, that *may* for some reason be different depending on whether it is White or Black to move; 2) Giving a variable but relatively large (sometimes 'huge') bonus for having the right to move, perhaps to reflect a normally always present potential 'initiative' stemming from the right to make the next move. >You should have a close look at the PV of the future S9!!!
