Had almost the exact same hand this weekend. $25NL 6MAX.

I held AKos and the board was:

K J 9

very tight passive tbl but the opp was newly arrived and neither
of us had reads.

I bet out 3x PFR got 1 caller.

I bet $1.50 on the flop and he raised me to $3.50.

He had about $7 left in his stack at that point. I had about $20 left in
mine.

I pushed all-in and he called with QT. Didn't get any further than TPTK
on the board.

I know I misplayed the hand by calling/raising. It occured to me that even in 6MAX (where people go in with all sorts of garbage) there is no way he would raise that hand unless he had 2pr or better or TPTK like me.
