Hand 2: 3-bet the river

Hand 1: I think calling down is fine with Aces up. Might raise the turn, but it costs you the same as calling down, you hand is fairly safe given you ahve 2 apir (you only fear trips, a gutshot or the improbabale OESD if ahead), deprives you of 2 outs to spike an Ace if you raise and old to a 3-bet (which will happen about 5% of the time), and, depending on your opponent, you may not be able to correctly assess what to do if 3-bet.
