Lloyd pretty much wrapped it up quite nicely so there's not much I can add to it.. Bet enough to make the other player make a mistake mathematically, but don't bet more than you have to.. and mix in your betting ranges so that they can't read you.. I don't mind value betting the pot, as long as you can mix in your other types of bets so that you're not predictable.. Remember that even though some bets will be fundamentally "incorrect", you have to implement them into your game as well to conceal your hand.
