Wait till the river?

[ISF]

Should I be waiting till the river here. Opponent was agressive so there was a chance he was showing agression with a weak hand.

it sure seems like he has an ace, and the chances that he will overplay a worse ace are greater on the turn.

naw i wouldnt bother waiting till the river,you mean you are afraid that too much agression from you will fold him?
usually they wil lcall all the way with any crap no matter how much you raise
