I actually like your line on this hand. As you mentioned, this is actually a deceptively ugly flop for you. The best hand you can hope the villian has would be Ax with x < or = 9. I would not want to be checkraising at this level as you may give someone with a hand worse than yours (a worse A) a chance to scare you off of it. Just be glad he decided not to test you out on the later streets.
