time for a cooperation play?

Hi all. I'm wondering what the right move in this situation is. Do I call with the intention of checking it down with BB, or is my hand good enough to reraise and isolate? UTG is desperate, so he's pushing with a lot of hands that I'm way ahead of. But is this the right time for some implicit collusion/cooperation (or whatever it's called) or should I go for the chips?
