KQo HU

if you dont have any reads of him 3betting like this (pretty small, OOP, while he may simply shove some hands over your minraise) with monsters only then i would say that it looks like a good spot for a 4bet shove.

as played he's giving you really nice odds on the turn but does he really have a lot of pocket pairs and flush draws that he's gonna double barrel to make it profitable im not sure. But anyway im really temted to peel one more like you did.

first time small 3bet? any other reads at all?

i dont think i can just fold this pre-flop to a reg so im going to flat.

is he good enough to know that you would 4bet strong aces pre?
is he aggro enough to try and 3 barrel bluff you off weak aces and Qx?

those are pretty important questions, im basically not folding this vs a reg who should be able to hand read and bluff in this spot often enough to call 1/4 pot on the flop 1/3 on the turn and half pot on river.
