Villain is 24/21/3.7 over about 100 hands.
No real reads other than he has 3bet my LP raises in resteal positions twice and I folded to both. I get the impression that he is somewhat aggro for these stakes, but I don't have any specific reads to back that up.

My image is clean other than a high steal %. I discount a pure float here as I have been playing rather tight. He realistically can't be on AK here. Is this a good place to CRAI the turn?
