hand 1 b/f turn you don't want someone with just one club to hit it on the river
even $3 does the job because if they call with a single club they won't have any implied odds

hand 2 river might be a puke fold, basically any draw he had just got there, and if he had 76 and was drawing to the 8 he just got two pair
if he had a flush draw he got there as well
but it's not the fact that he bet into you for three streets, I'd call a blank river for sure

hand 3 bet turn, we're repping a missed flush draw that just got a good barreling card
even if he's going to fold a lot of the hands we beat, we still have redraws against better hands and we just have a lot of equity
