Pocket Aces and a beginner

[HouseCalls]

Preflop - good
Flop - Fine but you have to be aware that there is a flush draw and a straight draw out that will coordinate with hgh cards that people love to play.
Turn - With the action so far CO's raise probably means you are dead but I think you just call down from here with top pair (plus if CO made two pair you may counterfeit him if the board pairs).
River - with this action I think you might fold to the raise (against one player call but the second player in can't be bluffing)
