Yeah that was what I was thinking for flop/turn. On river my thought process was as followed (what is written between what do you call these things is background info i know and might be important to clarify why i think somehting):

Hmm pot, normally a bit big for value (most standard players use 2/3 or 3/4 pot and dont fire 3 shots very often either), but this doesnt seem like a standard TAG the way he's bet so far. I've shown I've got a hand here by calling twice, so he might think he can get value out of me here and try to maximize it by making it look bluffy. (at this site they have a bet pot button and I found most regs use this as a bluff a lot, but I have no reads of him doing something likewise) Also can he expect me to fold an ace here? I also still have better hands then just an ace in my range, so I'm leaning towards folding this time.
