Very tough here. You really gotta work your reads and put him on a range of hands. The only hands that I think would make sense here with all the information would be possibly KQspades , A10, AK or 99/1010. Its unlikely he played KQs or A10 for a raise in UTG+1. I wouldnt be surprised if he shows 99 or 1010 here.

If you have a bad gut feeling about the hand I might just let it go. But if you fold you're going to be down to only 10BBs (an M of about 8).

If you push you're giving him about 4000 to win 6000 or about 1.3 to 1. I have a feeling hes going to call this bet pretty often and hes going to be ahead.

I'd probably give it up and try to find a favourable situation to start moving all in or stealing blinds, changing gears into major aggressive mode for a while and see if I can build a stack.

This hand is heavily read dependent, period.
