The programmer, Ed Trice, wishes to thank Bob Curtiss, Dan Morrow, and Shree Kotay for their help.  Their significant contributions during the lifetime of this project warrants special mention.  Three other people were instrumental in shaping the final version.  Brian Fitzgerald introduced me to alternative counting systems, and the means to calculate their respective ‘deviation %’ from the actual constitution of the shoe.  Because of Brian's recommendations, players can now alter the ‘Best Play’ tables and ‘Counting System’ values.  Bill Steinberg completely debugged an annoying bomb on the (new at the time) Duo 230 line.  Without Bill's help this project may have never gone forward.  Don Picard scrutinized my ‘Best Play’ tables and found several statistically unrecommended plays!  Thanks to Don the most horrendous oversights are now completely fixed.  A sincere thanks to all.
