Hand 1 is a clear check/evaluate. If it goes bet/call before it even gets back to you, easy fold. If the bet comes from EP, then my read is pretty important, but I'm probably folding. If the bet comes from the last person to act, then unless he is a rock, I'm probably CRing all-in.

Hand 2: I don't really like a push here. Anyone who calls will be getting better than 2:1, and this should be an easy call for lots of hands that destroy your range.
