short term adjustment vs huge position 3b

[oskar]

There's a reg-ish looking guy who I have seen pot 3b and squeeze suited gap connectors IP against EP raises. I only have about 200 hands on him, but from what I have seen he looks solid post flop - can hand read etc.

For now I haven't had really interesting hands with him at the table. I have opted not to open or iso the bottom of my range with him IP, but that's it.
I don't know how he plays against 4-bets. Obviously 4b jamming small pp's, AQo+ for <= 100bb should be immediately profitable until he adjusts. Prolly 4b 3.5x with JJ+, AK and see what he does for now.
I currently don't really have a calling range in those spots against him.

thoughts?

Why not include a 4bet bluffing range? Is he going apeshit with these 3bets or just sporadically doing it?

Also why not start flatting the 3bets? Both with monsters and a good top pair type hands. You could figure out some boards where your range > than his and be able to bluff/float with them most likely. Especially if you show down a slowplayed high PP.

Most are these are questions because to me it seems to make sense but better players may say no.

don't agree with 4b jamming craploads esp from EP. I'd start 4bing garbagey hands a bit but then again if you're opening like K8s utgish in fr thats probably a giant mistake. I'd just 4b like 2.1x anything with like solid blockers and probably call it off with QQ+, AK to a shove. i'd probably flat a bit with AA though mebbe KK.

flatting 3bs is also a giant mistake oop with stuff like KQ, reverse implied odds and such. if money goes in on like Q76 when you flatted a 3b UTG from like the HJ to this guy you probably are gonna get owned. alot.

4b small like 2-2.25x with hands that play well against his 4b range so that he feels compelled to flat preflop and then you can pwn his ass.

i flat tons and lead flops and stuff, a lot of people have trouble with this though.

Once I know him better I can definitely do a lot of flatting and 4-betting small. The reason why I thought 4b jamming might be better is that I don't really know how he plays post flop so it comes down to just guessing.
2x 4-betting trash oop and then leading any flop small is also kind of sexy, because I think he's good enough to put me on the nuts there, but idk.

kmind - both times I saw him 3b and show down, it was against an EP open. Obviously most of the time I'm going to be in LP with 200+ hand range. If I 4b jam 55-TT there, that's not really a lot.
I've thought a bit about it tho... stats say he's 3-betting wide enough to make jamming 55-TT profitable no matter how his calling range looks like, but if he's for some reason flatting or folding low suited aces and connectors, then I'm pwning myself really hard.
