If a bad beat crippled me at the ft leaving me 3 bb's those chips would be in the middle next hand.
UTG with 52o? Personally I think there's also a threshold where you get so short that you can fold atc as you know you're being called and behind.
With a little bit of FE I agree it's atc but with none I can fold some hands.
Agreed I am pretty sure folding the bottom 20-25% of your range is +ev, if not wider.
My line, especially live, would be similar. Your getting called no matter what so I would be looking for as good a hand as poss before the blinds hit again. You will prob ladder as well
