Flopped nut flush draw from SB 3/6 6-max

First time posting a hand so let me know what's wrong with the post, I just got started with limit last week...

Second hand at the table, MP is 72/7 at 1/2 6-max, no stats for 3/6.

Is this a fold preflop? I think I'd definitely complete at 1/2 with 0.5/1 blinds.

I think the flop bet was good, but was the turn bet correct?

Obviously, there's no reason to try checkraising such a passive player.

you might want to consider posting this in the HUSH forum (Heads up and Short Handed) that usually deals with 6 max games.
The hand is fine without reads, bet the turn because its heads up and you have no reason to believe you are behind, you could try for a check raise unless you believe him to be that passive.

The preflop call is boardline as you have only invested 1/3 of a bet, but the game is running 5 handed and when it starts to get this shorthanded high card strength starts to become very important so I think the call is fine.

The turn is the next closest street where check/calling might be better than bet/calling. Given this guy is uber loose you probably have little fold equity so checking is probably better. Nice river bet.
