playok.com might be a good reference. it has all the bases covered and a great balance between simplicity and features, plus an active community. I played your othello bot and it was really easy, maybe you could use some of the open source othello programs like edax to make a more challenging computer? http://abulmo.perso.neuf.fr/edax/4.3/index.htm
