I'm no rookie, but this is a move I don't understand. I've noticed that every time I use it, it's from OOP (obviously) and I'm bluffing - trying to represent a big hand to pick off a continuation bet. But if I really had that big hand, why would I want to push the opponent off the hand so soon? Therefore, it seems like the better bluff is to call, then try to take the hand down on the turn. So what is the value of the flop check/raise? Is it to actually represent a bluff when you have a good made hand? If that is the case, it seems like it would only be a good move if you have the nuts, because you would only expect to get called by better hands (i.e if you check/raise TPTK, you will theoretically only be getting called called by two pair, trips, etc). But if you have the nuts, wouldn't you want to slow play a lot more, especially if opponent is firing bets off?

I'm about ready to start reraising, every time, flop check/raises. Someone enlighten me here.
