Got a ton of dynamic with this guy. He seems kinda standard ABC but then our table broke down (this is the second time) and we made it HU.

He would 3bet me quite a bit. I would 3bet quite merged range against him and he would call quite a bit. He's raise/folded postflop after calling 3bet, he's 4bet/folded a few times, I called his 4bet and he showed down 95s. I was basically crushing his soul for a while and I felt like he was super spazzy HU.

This hand was pure value 3bet, expected a call from his 82o, but I think I'm doing pretty good in terms of FE given that he's 4betting quite a bit and he has shown me that he 4bets way too wide.

I kinda expect him to call it off with {TT+,AQs+,AKo}[2.94%, #39]. I don't really know what he's 4betting for value with, or how wide it is, but I assume he's gonna be a bit wider than standard QQ+ AK. I also guess he's polarised given his 95s.

If I have >62% FE against him then it is a +EV shove. For example if he is 4bet.folding {A2s-A5s,K2s-K5s,A7o-A9o,K8o-K9o}[6.94%, #79]. This makes our FE 67% and our EV of shoving +3.6bb.

But is calling probably better since I totally crush his 4betting range with ATs?

Also what sort of range should I actually be doing this with against this player? Could I adjust and 3bet/shove with 22+ and AQ+ only? I haven't really looked at this spot before.
