With how this is written its pretty hard to work out a lot of the details of the hand. I think the flop is 5 way. If thats true then you are very likely to be behind to a K, which will not fold to a bet. You also have almost no chance of outdrawing a K. You should probably check the flop expecting to fold to a decent sized bet. If the flop checks through, and the turn is not an A,Q or J then you might think about trying to extract a little value. Your flop bet commits you with a hand that is likely to be second (or even third) best with little chance of improving.
