Villian should have 15-20% 3bet here since the opener is a 60/15 fish who will give up a lot and they're nearly 200bbs. I wanna know if the FE I have against some kkxx and axxx combos combined with deception when I hit some great or not so great flops, and just having a hand like this to balance in this spot, will make up for having 40% equity againt villian's range?

villian's stats= vpip 30, pfr 22, 3b 9, fold to 4b 14, cbet flop 74

My perceived range is pretty much 100% aaxx and akkx
