UTG is imo a crappy player, would have called these bets with A-junk or drawing to a flush.
BB however seems like more of a solid player.

The turn bet is a probe, cause' I'm scared of a straight here.
I decided to check the river to see where I stand and called the bet because it was imo too weak to represent a nut straight. What do ya think?
