I agree with Jason about the merits of betting the turn. I also think that leading the river is better because at this point he might very well be confused into looking you up with a non A hand while he might also check those hands behind to get to showdown (with my mediocre hands in situations like this I often take that line, figuring betting the turn and checking the river will get me to showdown cheaper than checking behind on the turn and calling a small river bet). On the other hand you aren't really particularly concerned about calling a raise since your almost certainly behind if you get popped.
