Button is youngish white guy who I think is a fishy reg
He has been playing to loose but raising a lot. He has been on the short stack (about $120) and losing for 3 hours. Now finally he has a $320 stack and I really feel his 3 bet range is quite wide here on the button now that he has a full stack

Button has $320 to start and hero covers. Hero has been raising quite a bit preflop but should have a tightish image.

Didn't like any options preflop. All in on flop?? Turn bet is tiny but could be getting strung along here.

Hero raises to $15 with JJ

2 callers button makes it $60. Hero calls.

Flop is T6 5

Flop ($150)
Hero checks. Button bets $50. Hero calls.

Turn ($250)
K

Hero checks. Button bets $90 and he has about $110 behind

flop can go either way I think; if you think his range is super wide here then I don't mind the call , especially having the J of d

AP I think you should call turn and look to play a river; I think his range could have plenty of draws and maybe some TX as well so will such little left behind I almost like a shove on the turn; it just sucks cuz AK and KQ got there but if his range is wide enough in your mind then I think it justifies ripping this in

4bet pre.

Hero is utg by the way
No idea if button is aware this means a tighter range

You seem to have a pretty good idea in OP.

I'd just shove pre if you think he's 3-betting wider, there's a lot of dead money and if we 4b to 190-200 we have a super awkward SPR otf

id jam flop, you're hating a million turns and the you flopped an overpair in a 3b pot SPR 2 w/ a diamond redraw.

Given the range you put him.

As played, probably calling turn. I think a made hand gii with < PSB left. There are several AdXx combos in his 3-b range.

I find preflop very tough. With regards to stacks and 3betting, I actually think in general the opposite is true (unless stacks gets super large and the initial raise and 3bet is relatively small), in that people will 3bet wider with smaller stacks because gambol gambol and that's all they can lose, whereas with bigger stacks they tighten up and become more conservative and don't want to punt their stack / cooler themselves. Like I think QQ is far more likely to 3bet $150 deep than they are $500 deep. So being that we're slightly deeper (although by no means very deep) I don't think he's getting out-of-line as much as you may think. Which puts us in a really awkward spot in that unless the callers are super loose, if we just call here we'll be HU OOP and he'll likely cbet most flops and put us in a tough spot in a low SPR pot (where we won't be getting setmining odds). It's kinda a gross spot and I agree that I don't like any of our options preflop, but I might lean to just folding and moving on (ETA: leaning towards a fold even more now that I know that we raised UTG).

This is likely the problem we were going to face postflop, in a very small SPR 2 pot (where any bet is stack committing, imo), facing the cbet, although on about as good a board as we can flop. Based on the 1/3 PSB sizing (does he really size like this with a naked overpair?), if I've gotten to this point, I might just go with my hand here and shove.

Pretty craptastic turn card as now AK got there. But our commitment decision should have been made long ago (likely preflop, or on the flop if we got that far).

4bet pre!

Call turn, evaluate river.

Wow, I find the complete opposite. Players tend to flat with a smaller stack hoping to hit something (or they just shove) they can gii with and start 3betting more in position to take advantage of having a full stack.

I guess it really comes down to reads. In my experience, with like $150 stacks people don't mind 3betting and gambooling it up with ATs/TT/etc., whereas with medium-large stacks they really don't want to open themselves up to getting 4bet or getting in big stacks preflop as a big dog in a cooler situation (even with stuff as strong as QQ).

If OPs preflop read is solid, then we should likely 4bet preflop. I'm just not as convinced about the read as OP is (although I wasn't there so what do I know, and I'm more talking about the general case).

Ship flop. Don't see any other valid options. If you broke down his ranges. I am fairly certain you would love the results

He ended up having AA so I was in horrible shape all the way.

Hard to tell if my read was way off or if I just ran into top of his range. Difficult to say when you have only played with someone for a few hours.

Its probably best to just assume everyone is a tight 3 bettor at these stakes until you are 100% convinced otherwise
