donkfest. call/raise/fold?

I guess it somewhat depends on how tight the 3 players LTA are, but I'm kind of at my limit of "things that could go wrong if I polarize" given the number of players already in the pot and how little I trust them to fold. You're just gonna end up in a bloated 3-way pot with KJo with dry overs or double backdoors with J9s or whatever.

So I'd just take whatever I think the raiser's range is and 3b the top half of it, and flat whatever remaining playable hands there are--PPs, suited BWs, Axs, I don't personally love low SCs in these spots but I can't prove they're a bad call either.

ETA: Okay, it's not going to be exactly the top half of the raiser's range given both the number of players left to act and how many are already in the pot--you get diminishing returns for each percentage point the raiser is wider than they should be. For your particular seat and the fact that at least one tight player has already VPIPed, there's gonna be pretty heavy gravitational pull toward 3bing around 10%, so I would default to that.

Also since I'm suggesting you have a flatting range in this particular seat against this particular size, it's more like the top 40% of their range.

You know what, forget everything I said, just 3b the top 10% of hands. You'll be much closer to correct over-applying that than misapplying any adjustments.

I would probably take whatever range that you would ISO raise over 3 limpers and then use that to 3bet to $50 here.

Top suited broadways or Ax. Basically hands that have flush + straight advantage and blocking the strongest hands in the ISO range. If they can call with KQo and AJo, I think it's a good spot, because they will miss a lot, and fold to aggression

They can easily be ISOing with bad Ax and hands like QTo and KTo as well...

We calling pp 88 and below. Squeezing any playable hands to get HU vs MP.

As for what playable hands is, it's all up to you on what you're comfortable playing.
Goal of the night get HU and play hands vs MP whenever possible.

There's only like 30 out there.

I would squeeze wide unless we know MP is a station pre. We should win uncontested plenty, so maybe 88+, a lot of broadways and some suited connectors (maybe some gappers).

This min raise iso is a joke and needs to be punished.

And from the original post will be by a tight player UTG limping to start the action. Absent seeing them limp here before this from player description is a limp raise situation more often than not.

Good spot to squeeze, but stick to the strong stuff. JJ+, AQ+, suited big cards. Make it like $50 and let them call with worse.

literally squeezing with nearly 100% of my range in this configuration. The hands im flatting are going to be nutmaker hands, mid PP's and random suited aces. Everything else like 78s, KQo, AJo, is getting squeezed vs this nonsense.
