How do you feel about the play in this hand? It felt good at the time, but maybe I should have been more aggr looking at it in retrospect. Do you reraise the turn? Do you raise the river?

Well I don't think I would get more aggressive.

while he could be on a draw you are behind to any set, and more likely, any other two pair with an A.

I don;t think I would have re-raised the turn. Most likely I would have called then check called the river.

but that's just me
