It's looking like he wants to play for stacks here. This puts us smack dab in the center of the dilemma overpairs w/mid sized stacks always face when they're played back at. Calling and folding to future action means we put in 1/3 of our stack just to give up, pushing ourselves really should only get called by hands that beat us, and folding to his check raise means we fold the best hand a good percentage of the time. Vs. an unknown, I think I give it up and watch him closely in the future to see how often he plays back at the preflop aggressor.
