My general rule is this... unless you're against a table of very tight players, never slowplay a great hand. If you've got players that fold to any type of aggression then slowplaying might be the key... but loose players should always have to pay to chase cards.

If you've got the goods, play like you've got the goods. I'd rather steal the blinds than let someone draw to beat me. If you've got them beat, and they're drawing to beat you, make them pay for every card they see.

You'll get beat sometimes, and bad beats occasionally, but chasing cards will eventually catch you, and betting the premium ones will pay out over time.
