Personally, I don't like the river c/r very much unless you really know your opponent. In this hand, the call on the flop dictates a hand that would probably not feel very confident betting the river, even though most hands would bet the turn after it pairs the A. If she raised the flop, and you check-called the turn, I'd feel better about the river c/r. As played, I think that even when you c/r the river, you would actually prefer your opponent to betting a hand worth a call, and not a complete bluff. The board is pretty scary, you are the pfr (more likely to have an A), and your opponent isn't likely to have another A.
