I raise or bet the flop (if my memory serves me correctly, I have raised a flopped royal before...I know I've raised with quads). Most players just don't put you on big hands when you show aggression on the flop...because many players like to wait for the turn...so they assume others are like that.
When the case ace falls on the turn, your opponent is less likely to put you on an ace....so, again, I'll bet it (hoping he CRs with a pocket pair or a Q). If he bets it, I'm likely to raise, hoping he'll call me down (or, maybe reraise). I don't like passing up on chances for my opponents to make huge mistakes...in an effort to MAYBE extract an extra bet.
Lastly, when you fast play your big hands...you get more respect when you fast play your draws/marginal hands...allowing you to steal some pots or get you to the river cheaper.
