Subject: Alpha-beta PV collection

Author: Andrew Wagner

Yes, I'm STILL having trouble with this. I'm attempting to emulate Bruce
Moreland's algorithm at http://www.seanet.com/~brucemo/topics/pv.htm and having
trouble. Can someone explain to me exactly what's going on there as far as
updating the PV? Is it assumed that MakeNextMove() and UnMakeMove() update the
line, so that when it hits a fail high it knows what moves were made to get
there? I just don't understand his explanation. I've tried numerous ways of
doing it, and can't get it to work. But I know I'm getting the root move
correctly...it's actually able to play a game now (though not too well). Any
help would be appreciated. Thanks!
