Thanks for comments.

0.25/0.5$ NL 10 player

Your dealt AK in MP, bet 4xBB and get 2 callers
Flop comes (AK6)
You bet the pot (8$) and get one fold and a call
Turn brings (T)
He has 25$ left in his stack.
You have 35$ left.
No good read on player
What do you put him on and what do you do
"Solution":
I only feared QJ, but I thought he had paired his ace or held AQ/J/X and was going for the flush.
I pushed all in - He called and showed QJ - River didn't help...
