As you may have noticed I stopped playing LOA, mainly because computers are better than humans. However I still play live.
On www.iggamecenter.com you can play for free. Currently there are hardly any LOA players there, that's why I wanna encourage people to make an appointment here.
Btw: I don't see iggamecenter as competitor, otherwise I wouldn't post it here. The games are live, not turned based and imho turn based is still the best method to learn a game, because you explore the game tree much more deeper and learn the hidden mechanics faster.
You might be right, I probably should give black hole a try, but I think it's just a question of time until someone adapts the program or writes one himself.
