3/6 - A couple hands from tonight

[Intent]

Hand 1
I'm thinking I should have just checked behind on the turn and folded the river UI against two other players. Is that correct?

Hand 2
I'm unsure on how to play weak aces against aggression, and this was my first hand at the table against this unknown, no reads. I figured a raise could be an A with a bigger kicker, a smaller pair, or a flush draw. I planned to fold if raised here on the turn. Is this correct?

Hand 3
Villian hadn't been at the table long, but he hadn't gotten out of line or done anything strange. I found his calls a little strange and got wimpy on the turn, obviously. On the river I couldn't see him checking an ace after I checked behind on the turn.

Hand 1: Bet the river.

Hand 2: Check-call all the way down, unless hes agro and will raise in flop, in which case check-raise the turn.

Hand 3: Easy turn bet. Not sure why you checked it, but you obviously foiled a c/r from an ace. How you played it, I fold the river. Pots too small to call.

Hand 1:
I like it, the board is draw heavy so they could be calling on a draw. I would take the free showdown, and expect to be shown T8 or something similar.

Hand 2:
Is the plan to bet/fold the turn, if he raises on the turn again, you can toss your Ace and not feel bad I think.

Hand 3:
Bet the turn, and call down a CR I think. If he just calls you can bet the river again.
