Nope. In the same time frame, they will get approximately the same ply depth. You must have a whoppersome time control to get to 14 plies, or a really fast machine. (Or you are considering end-game with a nearly bare board). If you can get to 14 ply at the opening, I would like to know what kind of a system you have. >I have seen some messages that said Hitech looked about 8ply in the middlegame >it running at 150Knps.

Ply depth is not a function of NPS. Fast searchers don't expend a lot of energy per ply and look at more 'absurd' position. Slow searchers spend a great deal of energy looking at a node and ignore nodes that look bad. But they will get about the same ply depth in the same time frame. At least that is my experience with Crafty/Rebel/Hiarcs.
