I'm pretty sure Bruce >mentioned that he doesn't use mobility, so I thought he might pipe up. >I'll send him a note. I have no mobility terms in Ferret, it seems to do fine without them. Sometimes it gets bad pieces, but so do other programs. I'm not opposed to mobility terms, maybe they work. If someone has experience with them, or knows of a professional program that *for sure* uses them (not just a deduction of the form, "they are very slow, so they must use mobility"), please let us know. I think it may be possible to be more sophisticated than this, without having to go to the trouble of iterating the pseudo-moves for the pieces. bruce
