I've only been sitting at this table for about 30 minutes or so. Never seen any of these players before but it's not that hard to figure out who's good vs. who's bad. I've been playing very tight/aggressive and most of the players were aware I wasn't involved in pots without big hands. One hand I came across was interesting to me, so I would like to hear how you would have played it.

I will note that Villain 1 is pretty lose, but has received AA 4 times in the 30 minutes I have been sitting there so he has been active a lot, but when he shows down he usually has the goods.

Villain 2 is pretty tight. Haven't seen him active in any showdowns yet.

Hero: ($350)
Villain 1: ($800)
Villain 2: ($600)

Hero: AQ

5 players limp, Hero raises on the BTN to $10, everyone folds except Villain 1(UTG) and Villain 2(CO).

Flop: AJ5

Villain 1 checks, Villain 2 bets $15...Hero??

I was confused to see Villain 2 take a stab at the pot after my pre-flop raise. I thought maybe he could have AJ or 55 and decided to flat-call him and re-evaluate on the turn.

Hero calls, Villain 1 folds.

Turn: 5

So now the board pairs, I figure that's a safe card for me and eliminate 55 from his range.

Villain 2 bets $45, hero...?????????

As soon as he bet I asked him how much he had behind him, and he froze and pointed to his chips instead of telling me a number. When people are afraid to talk I take that as a sign of weakness; however, if I call and he fires big at the pot again on the river I will probably tank for about 5 minutes not knowing what to do. I really don't believe he would limp in the CO with AJ or AK, but again, I am confused as to how this hand is playing out so far.

Opinions? Should I have played it differently?

30 minutes of perceived tightness isn't enough to not call turn and call most river bets that aren't pot-sized or near pot-sized. At any rate its sort of doubtful that either of them would limp/call with a lot of hands that beat you, so the turn at the very least is a pretty easy call. River is debatable but unless you have a specific read that he's strong on the river which you seem absent of then it's probably a call there as well.

Why do you say you are aggressive?

Villain bets 1/2 pot on flop and 2/3 pot on turn. I wouldn't expect them to fire out a huge bet on the river; probably somewhere in the neighborhood of $75-100. I probably just call turn and calldown non-diamond river if villain bets around that amount. If villain bets much bigger on river we probably fold.

Villain limped cutoff and donked into us for half the pot. This doesn't look that strong to me and looks like a blocker sort of. Big flush draws, random ace hands and combo draws. Our only real concerns about being beat on the turn are A5 and 5d6d. I'd expect to see 3d4d here a good bit too.

If we're folding here what exactly do we need minimum to call?

I also raise to more than $10 preflop on the button with 5 limpers and AQ. Probably make it around $20.

SoZ you ran into A5 or quads

you have to call flop
ge could be betting for info with his weak aces A2+

Once you call he could put you on K10 or a FD Kk, QQ
his range is still wide on turn so you call.

River is tough
How thin do you think he would value bet?
would he bluff a missed draw?

Your hand looks like Ax to him IMO so if he bet big I could consider folding

a bunch of 5x in his range
A5, 55, J5s, Imo AJ less likely people normally pot it on flop
