appreciate the responses but you are all wrong. i ended up calling his $30 bet on the river surmising that with a 3 bet preflop, if he had any poket pair he would have liked the 632 flop and would have continuation bet. but since he checked to me on the flop and just called my bet he likely didnt hit the flop, and i assume that he wouldnt 3 bet with 66, 33, or 22 based on what i had seen at that table. i really didnt think he had a pair and called him with AK high, and he sheepishly showed down KQ.
