Hero ???


I see a handful of shortstackers who 4b jam like this fairly often; BTN in particular I have seen do it with both 55 and 98s, so clearly if CO wasn't in the hand it would be an easy call. As it stands... I actually have no idea which of the three options is best.

Instinctively calling seems worst, as CO will jam often when I'm far behind and I'd probably have to call anyway getting over 3:1, whereas if CO calls I mostly flop nothing and either check/fold almost half my stack or cbet the other half with only 2 chances to hit; jamming another 107.5bb into a 9bb 3bet doesn't seem fantastic either, even with the ~11% 3bet stat; folding AKo vs someone I've seen jam 98s would make me really sad.

Help?

While I'm at it, what changes if I'm holding QQ here? JJ? AQs? I'd guess JJ and AQs are folds and QQ has the same answer as AKo, but I don't really know how to approach this so I could be wrong.

This is a easy Stove exercise since you said you would call the shortie.

You open UTG. CO 3bets.

What is his range to 3! YOU ??? (we don't have stats on you)

Plug it in and your answer should reveal itself with all the dead money already in the pot.
