I would have re-iso'd UTG in this spot and looked to get the chips in ASAP on good flops. UTG+1 could have a very wide range and our hand is not going to play so well 3-way OOP.

I think a call is fine here. UTG is probably a fish considering his stacksize and limp but I'm not to sure about UTG+1. I think I'd prefer to setmine here with a weaker player in the pot rather than having UTG fold and playing a 3bet pot OOP vs a possible reg with a range advantage.

If we just flat pre or if we re-iso this comes down to the same thing. It is a call.

We cannot fold JJ vs a limp jam UTG for 40BB.

I would just call preflop. It's not really strong enough to 3bet vs MP while OOP, and I doubt the fact that it's an iso-raise changes it that much.

Vs a 40bb stack we are likely committed with JJ and should call. I wouldn't be super excited, he probably has AA, but not frequently enough that I would find a fold.
