Not a bad beat but a bad turn card for me.

So Im sitting in my local casino playing 1-3 NL. I hit a boat earlier that didnt get paid on the river by 2 drawers but Im doing okay and up a hundred (400 total). Guy in the 3 seat who has only been there an hour and already more than doubled up (AA 2x that held up) opens for $15. I look down at KK and 3 bet to $50. He smooth calls and I am in position. At this point, I believe he has a decent range AA-22 AK,AQs,AJs,ATs. Flop comes AA2 rainbow. He checks in the dark and I check as well. The turn comes a King. He checks again and I bet 50 and he reraises to 150. I flat here thinking, he probably has an AQ,AJ, or AT and I can get all the money in on the river with ease no matter what comes, even a Q,J,or T. A queen does hit the river but I call his all in river bet anyway. I have a full house, I cant lay it down. he turns over an AK and takes all my money. Turns out that on the flop I was drawing dead. However, I dont stack off here unless the case King hits the turn or river. Bad luck for me.
