Generally I overfold to 3-bets based on my population read (25NL Bovada), but didn't realize how active this reg had been (5/36) 3-bet wise, otherwise I may have 4-bet this for value. Other stats didn't raise any particular alarm bells (55.6 cbet, 50 f cbet, 31.3 WWSF).

Not sure what to do on this turn. Doubt V is getting too out of line here based on the standard c-bet stat. Standard call? Looking back on it I think I prefer a flop x/r. Range is capped pre, I 4-bet AA-JJ, AK, and A2s-A5s at some frequency. I probably call 77 pre.

Also I've switched up my style slightly and am trying to close the gap between VPIP and PFR.

FWIW I plugged this into GTO+, and the line it recommends depends vastly on how generous I am with V's 3-bet range.

If I give myself TT-66,AQs-ATs,KQs-KTs,QJs-QTs,JTs,AQo and V AA-TT,AKs-AJs,KQs,AKo-AQo (with only option being a 40% bet) it recommends a range bet from V, then a flat call from me, then pretty much folding on the turn if V fires a second bullet (which it recommends 40% of the time)

If I give V something like AA-99,AKs-ATs,KQs-KTs,QJs-QTs,JTs,AKo-AJo,[50.0]A5s-A2s,T9s,98s,87s,76s[/50.0] (with only option being 40% pot bet and 75% pot raises from me), it recommends V bet 60% of the time, and that I x/r about 30% of the time with AdQd. Then on the turn it recommends V bet 70% of the time, and that I mostly call but fold like 10% of the time.

Don't know if this makes my decision any easier, as I'm still kind of unsure what V's 3-bet range looks like

I think you're calling the 3-bet too often OOP if you've got AQo and all those suited hands in your flatting range. When you're UTG you shouldn't be calling 3-bets OOP very often. [EDIT: Oh, you're in CO? I misread the info. I guess your flatting range is more reasonable for that spot.]
Post-flop I guess it depends on whether villain has stuff like 65s and A5hh/A3hh in his range. Those bluff combos (and similar) would be in my 3-bet and barreling range, so you'd probably have to call the turn with AQs. It's way up in your range, and you should only be folding the turn if villain is heavily weighted towards QQ+/AK when he takes this line.

Yeah I think this call is correct vs. this villain. I ended up folding, figuring that even against a loose range this isn't much better than break-even, and that this call is catastrophic against a tighter range. I wasn't paying close enough attention to how active a 3-bettor V was.

Snap call turn

im agree on what you say we can raise otf.

AP i think im calling turn, folding river.
