I think you are right KingJack. I should have checked and called any bet, He may bet the flush and If he has quad Qs or a higher full house he will probably make a smaller bet to induce a call.

My point is that if the board wasnt 3 suited I could easily put him on a possible range of hands including AQ, QK, AA, KK (all of which I've seen people call all ins with on that sort of board with no flush possible). E.g a guy with QK could put me on AA/KK. Does the flush possibility actually devalue a small full house?
