CO had come new to the table with a 100bb stack and posted the BB in the CO, I wasn't sure what to make out of it since I saw him earlier opensitting some 5/5 games and had no reads or history with him so far.

We open a great hand to 4bb, I was even considering potting since everybody else on the table was also a fish (40-65 vpip 5-6handed), we get flatted by the poster as well as by the BB who we are about 200bb deep against.

We get a decent board, flopping middlepair and backdoor everything, I cbet 2/3 pot which I think is fine here and we get 2,5x raised by the poster. BB folds and we face a decission. There are no draws out expcept for 542* hands , even against those we are doing fine I think. I don't see him having AA** ever as I think he would 3bet his post always with such a hand, so we are left with 88 (1combo), 33 and all the 2pairs. As I think I can leverage his stack with a smallish 3bet (as here to 200, not 160 as shown) and he's to fold a decent portion of his 2pairs and even if called we got plenty of turns that are giving us plenty of equity, I thought of this as a good bluffspot for me, yet not sure what you guys think about it and how profitable this play might end up being
