With no reads and the fact that hes a half stack, he also has AKo fairly often. I agree with the set hunting line though once he reraises.

If you are going to 3-bet I dont think you can fold to the push without a read at these stakes. Not too sure of this so id like to hear what the other 10NL folks say but I think there is enough chance he has AK, AQ, JJ, TT to call the push once you have over half your stack in.
