Preflop: I didnt cap with it heads up for some deception value.

Flop: Standard c/r against his preflop. I decide not to cap again just b/c he is showing so much strength

Turn: Is capping standard? The only hands I am worried about are JJ and AA.

River: After he raises me again I think b/c is about all I can do profitably.

How bad did I mess this up?
