I think almost anyone would bet the ace if checked to and the percent is so high that I check/call no matter what. If he has the ace and i check river he'll probably bet smallish on river too to keep the bluff going and I'll call that too. If he has it Ive been value towned and I'll make a note. But I think most of the time check call check call takes the money (he value towns himself) and he'll probably freak out about "how can you call that your horrible..." and tilt him as most of the time it'll be a bluff in my experience...when he flips over his J-J
