i dont get it..how are u not worried about the ace against a polarized range?
He has flatted preflop and on the flop .. He would have raised on the flop for sure if he had A
a) To prevent any draws b) to see where he was .. i.e to check whether I had an A … if he flat called with an A on the flop it would not gain him any information as to my holding since he flatted preflop … hence I ruled out him having an A in his hand.
