3-way pot on a 7 high flop with a slight overpair, wasn't sure how to approach his spot. On the flop I was deciding between a x/ or b/, I went with a large bet in order to protect my slight overpair, 3-ways I'll likely be outdrawn otherwise (would have played a flush draw/premium overpair the same). BTN raises, I put them on a flush draw, overpair, set, maybe some type of straight draw. Turn is awful for me, now I'm really only ahead of any non-combo straights. River I bet small as a blocker, but realize there wasn't much I would even beat there so it was a bad bet IMO.
How should I have played this? As played, am I correct to think that blocker bet was a mistake?
