AA- and I´m helpless

[You're No Daisy]

You played the hand correctly. Checking the river is good because though you have Aces, it's only one pair and you're out of position. Villain could be playing two pair so if you bet the river, you're generally getting called by a hand that beats you. I'm assuming villain has AJ, KJ, QJ, or a busted straight since he checked behind on the river? Because you're out of position and villain has called on the flop and turn, there's no reason to bet the river. I doubt he has a straight because he would have put in a large bet on the river. As I said before, checking the river is good here. I'd probably call a reasonably sized bet on the river (i.e. 1/4 of the pot but nothing bigger). If villain was chasing a straight, take notes on him and keep exploiting that weakness. Nice hand.
