[sh0wtime]

Thanks for the detailed analysis Pokey. However, I think a set is an unlikely holding for villain. KK and JJ would most likely reraise us preflop and 99 could go either way. I would also argue that a smooth call does not neccessarily give away that we are drawing- I think it's feasible for villain to assume we could play KQ, QJ or even AK this way. Having said that I generally 3 bet this flop against fairly aggressive opponents and just call most of the time against passive ones.

EDIT: Against an unknown, I probably just call.
