Hand 1 is standard. I had a guy do this to me w/ KQs the other day.

Hand 2, just fold that UTG...even at 6-max that is a fold just about always. But as played, yeah, you have to be that turn as a lot of the time it's a FD or even a worse ace. Then you can check the river and see it for free or cheap (although here that river sucks, oh well ).
