BB was pretty tight. I had been at this table for a little while and my image was probably a bit of a pushover post flop. I had caught TPTK on a 2-suited board board several times but gotten raised out when the draw card came.

I called the turn raise thinking I needed a 10 or A to win the pot. That didn't come and the river bet was 3/4 of my remaining stack making it look like he wanted me to push, so I bailed.
Looking back over this, I am thinking that a lower two pair or very nice bluff is entirely possible here... Comments? Would you have played it differently?

I think that he almost definitely had the straight given his actions on the turn and river (if he was bluffing on the turn here, he'd be very unlikely to continue his bluff on the river after you'd called his check-raise), but I would also guess that he had a pair other than aces on the flop. The most likely hands are probably K-Q or Q-J.

Also, the size of the river bet is pretty uncharacteristic of bluffs, I think.
