I would just do a standard 3.5-4X 3bet. If UTG is aggro, he may 4bet it. Btn is likely to fold or shove. So if you don't want to build a big pot with a speculative hand, you might want to just call and see a cheap flop. If you hit a good flop, just let the aggro whale value-town himself. If you miss the flop then you can get out cheap.
