1/3, in the big blind, $400 eff, just sat down (first hand). get 55

1 limp, unk makes it $12 HJ, SB 3b to $35.

fold?

what it if it was $500 effective? $800?

fold 100% in every scenario

This situation is an easy one to apply 4!/fold to me. This is an easy fold for me because I don't like 4!ing with 55 here against the SB's range in a large pot. I think we can have a wider range if this 3! was against a button open, fwiw.

And if you flat, you'll also have to flat some of your premiums as well. But you're sacrificing EV by not 4! with AA, KK, AKs. So you end up defining your range to only a few hands, in a big pot, without the initiative. Whereas your opponents range is less defined, and they can play better against you. Plus, the og raiser has amazing odds to call now.

Fwiw, my SB 3! range vs a HJ open is [TT+, QJs+, K10s+, A10s+, AKo, A5s(as a bluff)] with some 88 and 99 mixed in depending on player. Given that I have no details on the SB, I'm going to give them a similar range.

Snap fold. Start considering cold 4bets with TT+ and mostly stronger

Fold seems super standard.

Fold.

Yeah, I also fold it's just a set mine. 10 to 1 is close to break even. 20 to 1 would be a good starting point. Plus, we can still flop a set and lose our stack, not to mention the 3bet range of an unknown SB has us crushed anyway.
