Hand 1:
I'm not sure how much I like that turn card. Its reasonably likely that a hand calling with a 10 on the flop just hit their two pair. I probably check call this turn. If villains are passive I might lead out again.
Hand 2:
I think you played this well. The only reasonable ace that you're beating here on the turn is AJ. I don't think AJ would be raising this flop though, so nh.
