$55 NLTRN: First hand 3bet pot w AQs

[emKay]

This was the very first hand of the match. According to SS he is a fairly big loser, thats all I know about him.
The turn check is kind of a slowplay obviously. A free card is very unlikely to hurt me, he might bluff with random chunk on the river and he may be more inclined to call with PPs. On the river, I'm very likely ahead plus I think a lot of donks are bad enought to make a curious call with their KK or whatever.
Here's the hand:

Bonus question: How much do you widen his 3betting range given this is the first hand? That much to actually 4bet here preflop?
