Hand 1: Naaah, no way can we call a shove, we don't actually beat anything. Only thing we can do is check and hope maybe he checks behind so we can get really thin showdown value/bluff value from sets/2prs.

Hand 2: I think it's close between c/c and b/f on that turn.. How often do we see random spades or 45 type of stuff there?
I'd prolly c/c and c/c a safe river (Which we won't see very often, but meh I think it's better than c/f all rivers)
