River Bluff, good 1/3 of the time?

[Roadstar]

Villain is LAG with unreasonably large preflop raises. At best his range is 22-JJ AJ-AK QJ, KQ. He's the type to actually slowplay AA/KK.

Is this good? $57 is approx how much villain has left.

Preflop reraise.. maybe even bigger?

Flop Cbet extra standard. Turn I was about to give up but check check really shows a weak hand from villain, probably ace face or 33,99 type. I could be slowplayed I guess.

The turn check check makes me think hes got A hi, so I want to bluff out AK and taking it down w/ AK although its an unecessary bet against AQ/AJ. Dunno if I can get TT/JJ to fold.

Thoughts?
