I'd like to have more of a read on the button, but such is life in a world of incomplete information.

I like this play better than if the turn-river had come Q-9 (instead of 9-Q). The way the hand has played decreases the likelihood of button having a Q (probably would have raised the flop) or a 9 (probably would have raised the turn).

From this hand only, button looks pretty passive here. But I don't know if there is any opponent you can lay down to here (absent a great read), because checking the river OOP on a double-paired borad is screaming for a bluff, even to the most casual player. You don't have to fold an A or a K too often here to make raising better than just calling....but I still think it is pretty marginal. I'm always amazed how many bad players have a hand like Q7 or T9 here.

I think I would much prefer a check-call line with AK or AJ, though. The possibility of folding an A is what makes me think that check-raising with KJ may be best.
