Decent opponent on small board

I am mainly looking for an AI opponent that is worth my time. The professional games are just a plus. Being a busy professional i cannot possibly commit a couple of hours to a game with a real person on regular basis, but do not want to give up the childhood hobby i was passionate about when i was young. SmartGo is a decent opponent on a 9x9 board, even though it becomes a joke on a full scale 19x19 board. I can beat it even allowing it 4 handicap stones on a 13x13 board, but still struggle with a 9x9 game on equal terms. It might just as well, since i really dont have that much time for a full game any way. It served the purpose. It did not get the full 5 stars because i still wish it could be stronger.
To disclose, i am probably at around 1 dan level.
