Hopefully a more interesting hand...is my A good?

I make it 400, opponent will probably raise wtih QT/66 and call with KJ, but fold AQ/KQ/QJ...I guess I don't like 3-betting preflop beacuse I'm in a difficult situation if the turn is a total brick. It might work in 6max since an opponent will lay down, but if they don't laydown then I'm stuck on the turn. I like your idea of leading the turn. Do you consider this a bet that is trying to slow the opponent down? If so, how much?
