Sorry for using pokerhand.org, easier to put them in my notes.

Hand 1: http://www.pokerhand.org/?1845939
I don't think I really can but I want to make sure a value bet on the river isn't good; villain is 13/10/6.0.

Hand 2: http://www.pokerhand.org/?1846169
Villain is unknown. Note his stack is ~50bb. Standard?

Hand 3: http://www.pokerhand.org/?1846393
Villain is 22/10 or so with a 1.0 flop AF and a 6.0 turn AF. I don't think he has an ace since he open completed the SB. His turn AF combined with his preflop completion make me think I'm good here, but when making my turn decision I'm not sure about the river.
