In this position, with this stack, I'd definitely be 3betting here. We 3bet and take down the pot right there, great. We 3bet and eliminate the BTN/blinds from coming along, (and/or them 3betting themselves) and potentially go heads up rather than 4/5 ways, great. We get 4bet from OR - we're deep enough and IP to call.
3betting here in this exact spot has so many advantages over flatting.
