20/40 on a boat draw

[mosch]

B&M 20/40, and I'm new to the table but it appears that it's playing normally, which is to say it seemed soft for a 20/40. Two known good players, and one who is more at my skill level (could be better). Rest are unknown to me.

UTG+1 calls, EMP raises, I three-bet, the BB makes it four. UTG+1 thinks for a while then calls, EMP and I both call.

EMP checks, I bet, EMP raises, I three-bet, EMP calls.

This was one of those hands where right up until I got check-raised on the river I felt like I was playing with my cards face up, and I just felt shaky about some of my decisions.
