Your bet sizing is making these decisions tougher than they have to be.

On hand one your hand is under repped your acting like you have a J and then checking the river screams "bluff me"

On hand two, instead of calling two weak bets on two streets for a total of $.54 try raising and taking this down now.

By the way, try giving a read or two to your HH's, it makes things a little easier. What did your notes say? What do they say now?
