I think the SB could be on anything and just hanging around. His raise means nothing and his bet on the flop means nothing though his call of the 3-bet back to him means he must have a piece.
LHO 3-bets this flop and, to me, this says set. I'm not dead certain but in my mind it was at least 50% likely. So scoring two pair on the end, LHO I know won't raise me because the flush got there but...am I even value betting here?
MP I have no reads on whatsoever except that this person has called every single bet, including two cold on the flop. No aggression whatsoever which means bad player but, to be honest, this is the one person in the hand I feared having the flush. Just not betting it because that's what passive players do. They make their hand and still expect others to bet it for them.

So to summarize: I thought there was a 50% likelyhood LHO had a set and I figured a 50% liklihood MP1 made his flush (yet isn't even betting). SB would bet his flush so I knew I was beating him.

Overall, am I value betting my two pair against four opponents here?
