Villain is running 28/22/2.5 and running good.
He is very tricky, he bluffs quite often and may bluff very hugely.

I would definately fold this against a more straighforforward player, but this one could easily bluffing for 200BB and the only real hand I may put him on is A8.

i think he expects you to call the river (or i think he expects to get looked up by your ace)

If the above statement is true, it just comes down to what level he/you are thinking on.

however, i myself am kind of a station, and once you show that you do make calldowns like these (or incapable of folding top pair) I think these people will not screw around with you as much in pots without the goods...But I really think your beat here. a "tricky" lag usually has it here in my experience.

Here are two hands with this guy to describe his style of playing:

OK, so he bluffs anytime a card that could possibly be a scare card comes.. Call. You could lose the hand but its +EV for sure IMO.
