AsKs

I think if you called on the flop, you have to bet the turn, and the river, to fold out 99-TT, and Jx hands. Maybe he folds weak Qxs bluff hands like Q9s, QTs too.

Hi,

I would usually start by 4betting preflop. You get so many calls from worse when you hold AKs in this spot.

What do you think your opponents preflop range is?

When he bets so big after 3betting pre it screams strength for me so I would not foat too light here..AKss is among the weakest hands I would consider calling. Your logic for calling though is that he cbets weak imo therefore you are sometimes ahead and you can also bluff him off some hands, otherwise it doesn't make much sense to call flop. Following that logic, you should bet turn imo, like DarkAwi said, to make him fold middle pairs and sometimes a low Qx.
