1-2 live: nut flush draw

[Bear Bones]

At a live $1-2 game (max $100 buy-in). Table is 10 handed Hero is BB with $125 and gets dealt Kc9c. Table is fairly passive. MP1, MP3 limps, CO limps, SB completes Hero checks. $7 pot after rake and the flop comes Ac8s3c checked to MP1 who bets $6, MP3 folds, CO pushes all in for $75, SB folds. MP1 is almost sure to fold based on his previous play and the smallish bet. CO has been tight in the 3 or so rounds I have been at the table laying down most hands and not showing any real agression before this hand. I feel like I am WAWB on this hand. Maybe 20% set, top two pair; 60% flush draw, 20% bluff. The problem comes with the flush draw and bluff hands that he has caught middle/bottom pair as well.

What is your experience in this situation? Do you call $75 with the nut flush draw into a $90 pot? Obviously, if the pot is $150 this is an instant call so where is the tipping point on this kind of move in a live game? What do you usually see villain show down with this move.

This is never a bluff. This is a set/top pair/2 pair more often then a flush draw.

Why do you think mp1 will fold? His bet was almost pot which is not small.

1) Table is fairly passive.
2) Everybody limps.
3) CO pushes all in for $75.

What do you usually see villain show down with this move.

A raggedy Ace that hit two pair.

It's an unraised pot with irrational and often passive live players. Usually, they are afraid of getting sucked out on and make stupid plays like "raising to shut out the flush draws."

Just fold.

I don't really expect to see that much aggression in a small pot with a huge made hand especially at a passive live game with a villain who seems pretty aware. He could re-raise here to $35 and give flush draws bad odds to call without committing his entire stack.

I think MP1 will fold because he has been playing fairly loose weak and I've seen him lay down to big bets. While a call from him would actually give me the right odds to call, but I'm not counting on that in my decision making process. Also, the standard post flop bet on a limped hand at this table has been $10+ so the $6 bet is kind of smallish in context.
