I think I played this a little too weak-tight... Was I right to fear the A /images/graemlins/club.gif, or should I have jammed the pot turn &amp; river?

3 bet the flop, definatly 3 bet turn too

i three bet turn, and let opponent's reaction dictate what I do on river. if he caps turn, i check call river. if he just calls my 3bet, i lead out on river.
