1bet2folds

Everybody folds to my button, and I make it my usual 3x from the button. I have been raising almost every button, so I wouldn't be surprised if the BB starts 3betting me light. Although his stats are quite nitty although I don't really have many hands on him (44) he's playing 9/9 with 8% 3bet out of 13 hands which is basically ony 1. Although he's a nit his postflop play is pretty aggressive with 6AF and postflop aggression 75% in 4 hands. He hasn't been to showdown yet though so I dunno what he holded.

So he 3bets me to $5 which is normal i guess and although I'm not thrilled playing in a a 3bet pot against this nit, I am calling IP with AQo. I didn't consider raising him, as if he's gonna call me I'm pretty much dead. Flop comes A28 with 2 diamonds and he leads $6. I make the call and turn comes J which brings a 2nd flush on the board. He bets $12 into $22 and I start to wonder if he really has AK or AA here. I personally think that if he had AK he would bet larger so that I couldn't call with a flush draw and the same goes with AA. I make the call and now the pot is $46 and on a 9 river he jams. I think I can rule out AK because he would be a little more sceptical as to why am I calling there and AJ got there so I can only call him with AQ and AT as A9 got there as well. Plus I get the pot odds to call the river, which I do and he shows QT for the runner runner nuts.

I didn't want to raise flop or turn as he's only jamming better and folding air and I think since I didn;t raise at any point in the hand he could have 3barelled me with air here sometimes? I'm not sure I'm really not sure about the hand. Did I make any mistakes in the hand? Let me know as I really don't know what the hell happened here :/
