Early on day 1 of Borgata ME. Only 1 guy at the table is over 30.
Reads:
Villain 1: young guy, Opened about 30-40% of hands in the last hour from early position. However, plays pretty straightforward post flop
KJulius: Been pretty tight so far. Seems more focused on finding a masseuse.
Hero/me: Tight/nitty so far. No hands. Not showed down any bad hands either. Pretty much won the blinds the 4-5 times I raised so far.
The Hand: Level 3 75/150
Villain 1 (15K) opens for 400 from UTG+1, KJulius (~30K) flats from HJ, I (~30K) look down at A

Q

and 3-bet to 1500 (yea, I know, more on this below). Villain 1 thinks for a bit and calls. Kyle calls pretty quickly behind.
Flop (4725): A

Q

9

Villain 1 checks, Kyle checks, I bet 2600, Villain 1 folds, Kyle thinks for like 5 seconds and calls pretty quickly.
Turn (~10K): 3

Kyle checks instantly, I check back.
River (~10K) 2

Kyle thinks for like 5seconds and then bets 6125. I ??
My thoughts:
Pre: I almost never 3-bet pre w this hand in this spot. But given that villain 1 was opening so many hands pre and my general image, I thought this might be good value as he is gonna either fold pre or check/fold the flop a lot.
Flop: Seemed std to me. Would like feedback tho.
Turn: His insta check led me to think, it was a WA/WB situation. My hand looks so much like AK that he folds all worse and calls/raises all better. so didnt think any point in betting. Also if I check the turn, may be it opens up my range a bit and he might bluff the river?
River: ??
