I have no idea about this hand, where it falls in my range and what line I should be taking vs a manic.

6 handed 1/2 live game that has some how turned into 2/5/T due to the presence of some wealthy whales.

Villain is a middle aged Korean American business man that's been super lag. Straggling UTG and BTN and often putting out a $30 blind bet in HJ and CO. Has been running super well against the other fish and has $4K.

He's been taking a lot of unusual lines, making a lot of over bets and has been caught bluffing or shown bluffs a lot and they're usually pretty random but he's not completely clueless.

Hero starts the hand with $600 and opens AKss to $30 in HJ and V calls in the LJ/straddle.

Flop is A63ddd.

V donks $50 and hero calls.

Turn is A63ddd 7x

V donks $200, what does hero do?

Not folding on the turn to this type of villian. Also wouldnt mind clicking it back on the flop. If villian 3 bets you can get away... you'll get a free river a lot and you'll have better control over the pot size.

I'm probably raising flop looking to play any non diamond turn very aggressively ; AP I think you could call or raise but he bet so big that I would lean towards calling hoping to fade a diamond on the river

I tend to agree that we should call and reevaluate on the river. Against this described villain, i'd imagine this is a draw a large percentage of the time. I'd call any non-diamond rivers.

Raising flop is interesting. Obviously in general you don't want to by raising single pairs here but against a moby dick, it could be a very good play considering we have position.
It's hands like these that make playing against whales such a risk/reward situation. You basically have to call him down on safe run-outs but whales can run hot just like anyone else.

fold flop not even giving it a second thought
pot sized bet flop and turn
your just torching money

Either raise the flop or fold vs. this type of player. As played, just fold.
