as for the hand, OMGWTFGETTHEMONEYINASFASTASYOUCANANDSAYMUAHAHAHAHA HAHAHAHAHA

as for the thought process, you don't even need 50% equity for this to be +EV because there's already a good bit of money in the pot. that being said, it's 275bb's deep so your 15bb that you already committed isn't a huge factor.

also, OP's and cougar's ranges are like way more optomistic than i'd like here. ok MAYBE he shows up withn 87s, but do we really expect him to show up with this hand with the exact frequency that he shows up with AA here, as your range suggests? there's a huge difference between min raising and calling your 3b with anything and min-raising then 4b massively overshoving. i mean the guy obv likes his hand.

I'd say something more like KQ, ATs+, AJ+, TT+ is a lot lot lot more realistic. that said, we still waffle crush his range
