Draw when heads up?

[wizard]

I believe that the call, based on my read, was wrong and I should have folded to the first bet before the turn. After calling and getting a blank on the turn, I felt committed and also went all in with my 15 outer. A blank hit and my opponent has the trophy. He had a KQ off. Two Dimes says that I'm a 53.5 to 46.5 dog after the flop and a 66 to 34 dog after the turn. Even if I have the odds, I believe I should try and get my chips in when I am in the lead. Draws are good for rign games or in the first few tourney rounds when the stacks are still deep but not for all the marbles. Thanks for the comments, observations and help.
