Seems pretty sketchy to me...check calling that flop sounds warning bells off in my head - so he won't bother betting with something like Q9 with one spade, or Ax with a spade, instead he'll take his free draw because he is good enough to realize you're probably check raising here.
-let me clarify, either you plan on check raising or seeing a cheap showdown - so those hands you have beat won't bother following through.

I like your plan if the turn wasn't a spade or a 2, which in some ways may bind you to a showdown here, no?
-is he aggressive enough to 3bet semibluff with something like AT w/the As?
What was your plan if 3bet?

I agree with your flatcall preflop w/ Axo btw. No question there.
