[Billy Baroo]

I'd raise this pre-flop. In a full game I'd consider calling UTG if it was likely to cause several players to take the flop; however, in this instance I'd want to raise because A) you are unlikely to get a big multi-way pot because it's shorthanded and B) there is extra blind money on the table because of the kill pot.

I think your play on the later streets was fine, but if I was in your shoes I would have raised before the flop.
