I'm going against the grain on this one and saying I would probably try and win a race and be in prime position to take this down. You said the opener is a fish, so I'm not giving him much credit. The 3-bettor apparently overvalues his hands so he could easily have AK or AQ here. I mean its a decision of whether we want to gamble or not and try to win a race, I mean we could sure find a better spot to get our money in but would we have the chipstack we would have if we win this hand. It may not be right but I take a chance here and shove. If UTG was somewhat competent I would lean more towards folding.
