AK vs laggy spewbox

Villain is 55/10 over a large sample . Very spewy postflop.
- 15% fold to cbet
- Floats flop OOP with no pair no draw. Barrels river with air if turn is checked back
- Min raises flop cbets IP
- Check raises flop and CRAI turn with FD

F: I did not raise flop because I don't think I can continue if he bet/3bets me. Although the flop is drawy, theres a lot of two pair combos that already have me crushed and I'd rather protect my stack than protect my hand from being outdrawn. Thoughts?
T: Turn probably should've been bigger and that was a value raise.
R: His flop and turn blocking bets put a lot of bottom/2nd pair hands into his range. A queen probably isn't doing this and bottom pair which caught trips is the only plausible hand combination I can see him having. I think this was the right fold?

Meh, I might pay this off. It depends.

I would certainly jam that flop and fire against on the turn.

As played, I would call because he doesnt have a 9.

Raise flop pot, raise turn 3/4 pot.

no way you can flat the flop bet. you're giving him perfect odds with a draw on a soaking wet board. since the initial bet is 2x min-bet, i wouldn't even really consider a re-raise from him to be a bet/3bet line. i would think of his range in that case moreso in terms of what he would raise the flop with if that happened not what would he 3bet the flop with.

anyway, def raise the turn more for the same reason. now that he's stop bet both streets i definitely put draws in his range just as much as BP or MP. as of the river i'm much more worried about KQ/JT/K9/Q9 that's been played retarded on a wet board than i am about a naked nine. i think busted draws are more likely here, especially given his stop bet/call line on the turn

knowing his call PFR stat always helps me put him on a reasonable range. different laggs have different reasons for folding PF and sometimes a PFR is one of them.
