I check/fold the flop here. Pairing your 6 doesn't do anything, so you really only have 2 effective outs (maybe 3 if you include the gutshot backdoor straight draw) that will improve your hand. In fact, I wouldn't even count the two 7's as full outs, since another 7 falling gives you the smaller full house against someone with a 9.

Combine that with the chances that someone has a 9, or an overcard falls that pairs somebody's hand, and I don't see much reason to invest another bet here.

From the river action, I'd say MP3 had a 9 and the button took down the pot with KJ, right?
