How's the play post-flop in this hand?

[Shargaas]

Or for that matter how many people 3-bet pre-flop? The table was loose with fits of aggression that weren't always connected with a good hand. I called out of the SB and intended to check-raise if I hit, which is what happened. Here's the hand.

3-bet preflop, 100% of the time.

Your flop and turn play are inconsistent. If MP1 is loose-aggressive, you should cap the flop and lead the turn if he checks to you. If you cap the flop and he bets again on the turn, just call him down.

I was the small blind so I had to act first in each round post-flop. I think I understand what you are saying, but my thinking was after he 3-bet me, I would call and see if a scare card came (the flush card being the most obvious). When it did not hit, I bet out again, but again he raised, and then I went into call-down mode.
