thanks for the comments.
Last night I was keeping an early NEW YEARS resolution to play tighter. Voila suddenly my raises were getting much more respect, too much so as often gamblers were not looking me up with my MP raises. I have been on a downswing so I tried my best to play ABC poker allnight and anyone watching the showdowns would have seen me win or lose with reasonable hands.
BTW he folded so as far is the table is concerned I likely had A high card.

Given my table image I guess when he bets into me in the flop after an ace boards I don't take it too seriously. It seemed like from his perspective he was trying to feel me out.
What I find difficult about this type of hand is how much information do you get from the flop round. After this flop I am either marginally ahead or way behind. I need to define his hand. Its quite possible he is sitting with QJo and called my preflop raise on that. He is going to put me on Ax as a starting hand so the flop raise is an attempt to confirm his suspisicions.
Now the dilema to this line is if he calls the flop raise and the turn is a blank do you fire another barrel hoping that he will fold and planning to check behind on the river if he doesn't?
I thought about giving a free card on the turn (I know he could beat me w/ a higher set or hit a backdoor flush draw)
but I figured given I had raised the flop (and played tight and aggressive all night) the free card would of been too transparent.
