im 3betting here all day for value. you don't wanna have AKo and go up against 4 other players. if u get 4bet then just flat and see the flop, no reason to 5bet shove 65bbs.

btw, 2.5-3k is waaaaaay too big of a sizing. with all those players in the pot and ur hand not being suited i'd make it 3.5x-4x at the most
