I open A2s+ from all spots

hand 1 I don't like the bet-sizing on the flop
hand 2 folding PF would be correct here, raising the turn or river has to be +EV at 10nl as you'll be called down by Ax.
hand 3 river is one of those annoying folds, he's shipping in 250+bb's and he doesn't expect you to fold an Ace, so prove him wrong.
