Villian is loose passive player. I didn't have too many reads on him at the time except that he check/calls a lot, limps a ton. Not too aggressive. I haven't seen him check raise. 

My Image: I've been raising a lot hands and winning without showdown up to this point with some double barrels. 

Effective stacks ~700

Preflop: 2 limpers, Hero raises to 30 from CO with AdAh. Both limpers call from EP somewhere. 

Flop ($97): KsQs9c

Limper checks, Villain donks for $65, Hero ????

I'm having trouble figuring out what a typical loose passive fish's donking range is here. Is it mostly for value with the wet board? Or maybe he's trying to draw at the flush/straight cheaply? AsXs, KT-KQ, Q9-QJ? 99-TT, some JJ (he might raise that PF). 

Folding seems pretty weak here.

If I call, do I just fold to the double barrel (depending on bet size)? Are many loose passive players double barreling KJ, KT and semi-blufing pair plus draws here? Not sure.... I planned on calling a turn bet on a blank turn card. Not sure about calling a river bet, I guess it would depend on the bet size. 

I could raise for value (assuming he donks with some drawy hands or Top pair type hands), folding to any 3 bets he makes on the flop. This lets me control the action going forward. Betting small on blank turns and checking back most rivers.
