This is based on gnuchess 4PL67 with many enhancements. Searchs more nodes per ply, so will get fewer ply on slow machines, but plays better. Also support for Super72 mode 800X600X64 or 256 colors. This version plays much more competitively vs skilled players and good computers, less daring against lesser opponents though. Fixed some bugs with resign, and a small bug in undo which caused mate msg to be displayed if you undid mate.
Bug fixes to load game, and to transposition table routines.
Major speedup of movelist routines, speed of search and eval greatly increased. Slight enhancement to endgame eval routines. Many changes incorporated from the Gnuchess 4PL64 release. Any changes that did not conflict with UChess specific changes, were merged into this version. Many changes to clock handling routine, UChess now manages its clock MUCH better, and thinking on opponents time is MUCH improved, making UChess far better than before when this feature is enabled.
