Hey guys, I was wondering if it is okay to change my main game when the table does:
- pretty much everyone just limp/call every hands, and close to no raise pre flop
- they will station a lot
- Trying to isolate the fish is hard because everyone calls preflop.
- close to no 3bet preflop (and when they do, they could have bad hands that for some reason the opted to 3bet, and not necessarily premium or aces)

in those terms above:
should I overlimp with hands like 9965ss, TT74ss, 3365ds or medium ace suited, or 3 big cards suited, bad jacks and queens?
should I defend with low rundowns?

or is it exactly the opposite of what I just said? Like I should play even more tighter and raise/value a lot more?

Tighten up, especially your preflop isolation raises

Don't 3bet less than premium hands unless it's a good situation for postflop isolation

Value bet like crazy

You can limp OTB with one-way nutting hands

If rake is high, play fewer hands, especially hands where it will be multiway

I have problems with good middle hands, like TT98, 7789ss, 6655ds, etc.
if there are lots of limps in front of me, should I raise or just overlimp?

You have problems because you're vs. Dominating draws. These hands aren't great anyway so it's ok to fold. It's also ok to limp behind it the pot is going to be multiway. Just dont overvalue your 2 pairs, bottom sets, draws multiway postflop

Double pairs are the only hands I would raise vs. Many limpers because I raise those hands from all positions

Trying to isolate at this table is stupid. You should consider tightening up on your raises, since your opponents are limping AA hands and can limp/reraise you. I would only raise with hands where you don't care if everyone calls and they all have top 50% hands.

Because you are getting in for cheap, you theoretically have more implied odds. But don't overestimate your implied odds because they probably won't be as cooperative in building a big pot with less than the nuts. You are basically against the same ranges as you would be up against at a table where every pot is raised with 7+ players in, you're just seeing flops for less preflop and a higher SPR. I would be careful post-flop because these players are probably going to be more passive with the second-nut or strong draw hands that will be rammed and jammed at a more aggressive table.

I don't think 6655ds is a good hand because they are limping with a lot of hands that will overset you. You can play it, so long as you understand it is a small pot hand where your goal is to avoid losing a big pot. You can get away with playing more hands with a dangler. Something like A992 is a hand that you should fold UTG at a table where it is often raised and reraised preflop, but you can limp with it at a passive table because usually you won't get punished with a raise behind you.

No matter how they play, PLO is still very much a post-flop game, so you want to consider what kind of flops your hand can hit and what sort of hands your opponents can have that will give you action.
