Well, with four players in the pot and an idiot BB, you can probably get your money out from him and force other players to fold any draws they might have. So, a bet into the flop would have been fine. I don't very much mind checking here, as you have a monster and so many cards can get you great EV from bad players (this include another club, spade, or diamond to give someone a draw, an ace, even a Q). On the other hand, against this rum group, building the pot early on the flop is probably the better idea.

Now: On the turn - MP RAISES all-in, BB calls. MP probably hit a higher set. This sucks. Small mistake v. big mistake. Let it go. Time to move on.
