That's an ugly one. I'm not sure right this second what the proper ruling would be.

The bb certainly should be kicked square in the nuts for this one. If this was a tourney I'd penalize the bb with significant time away from the table, at least 20 minutes or 2 full rounds depending on house policies. If it were a live casino game I'd have this guy in the back reaming him a new one.

The problem, obviously, is that JJ had very significant information before he acts that he was not entitled to have, and TT did not have when he acted.

A possible solution would be to declare that action was dead at the point where the bb exposed his cards, and to disallow any side pot action. I'm reserving this being my "final answer, Regis" until I see some replies and ask around some.
