Well... one option is to just fold the flop. That is an overbet and you are OOP. Still, with an added caller in there it's not a big mistake. Once it gets miniraised and gets back to you, you clearly have the odds so easy call there.

On the turn you have to dump it. You're 20% to make your hand and you're putting in 30% of the money, not a good deal. Since BB mini-check/raised the whole field on the flop you have to assume he has a monster, most likely a set although two-pair isn't impossible since he was in the BB. Against two-pair you have more outs (35% or so) but against a set your outs are decimated (like 16%) so all together you still can't call.

The overbet by MP2 on the flop actually went unnoticed until I reviewed the hand with PT. I was playing 3 tables so I think I may need to cut back if these types of things are going unnoticed.

Thanks for the help.
