I hate the turn check because you're giving him a chance to catch up. A check on the turn after a checkraise on flop usually indicates an attempted checkraise bluff with AK or a small pocket pair.

He also could have AQ here which if is the case you got unlucky but had you bet turn he surely would have folded.

Also if he pushes river you cant call which a lot of good players would do sensing weakness with your check on turn
