KK facing huge river bet

Our opponent is generally quite aggressive. I have seen this opp raise AI on the turn river against several opps with stacks sizes of $2-5.

I'm not a good cash player (yet) but I am reasonably sure we don't want to raise the flop and get pushed off the nut flush draw. Should I be betting the turn once he checks?

Given our read should we call the river bet? Personally I think this is a case of being way ahead or way behind. I don't think the K makes much difference other than completing an unlikely straight draw.

Further info

44/25/5.0 over 48. As I said already, she was pretty much trying to push the weak-tight players around by making big AI bets on the turn and river (and succeeded in every single one I saw so far).

PS Does anyone know of a good Pacific Poker hand converter?

Lol, I was about to say please use a converter till I read the end:P no sorry.

With your read on how he is betting like a retard on the turn/rivers I would snap call this.
I also don't like betting the turn, we don't want to raise and get forced to fold with the best hand. Also If you don't bet the flop what are you representing by betting the turn.
An ace isn't checking that flop.

I don't think I could ever fold here.

Gotta call now but bet turn smallish. His range is behind your hand.

Yeah i would have also called the river bet on this, more often then not he's got ace rag and flopped top pair, unless you got unlucky and he flopped flush or rivered an unlikely straight

I think it's fine vs a maniac.
You could bet the flop and hope he'll get it in with some pair and flushdraw that you have drawing to one card.

How is folding the river an option? I don't get it.

Yeah I wouldn't be able to lay it down either, I think he might of been trying to slow-play aces, or he sensed weakness and tried to scare you away.
