that others can learn from (maybe). I should have bet $50 on the flop to get the shortie to call all-in and MP to fold......correct?

Or is this just being results oriented?

Results in white below:
Hero has Jh Jd (two pair, jacks and eights).
MP has Ks Ah (one pair, eights).
Button has 6h 6c (full house, sixes full of eights).
Outcome: Button wins $218.60.

P.S. This is not a bad beat post. All of this could have been avoided with a larger re-raise preflop which guarentees me to be heads up with the shorty. Or is my thinking totally off here and it just sucks that dude hit a set?
