It took me a sec, but now I see the problem. If seat 7 pushes, seat 3 will have extra information to decide whether or not he wants to call the significant sidebet.

However, in theory this shouldn't have a big impact on how seat 3 acts, since there are only a few rare instances where knowledge of seat 2's card will have an impact on seat 3's decision to call all-in or not. Even in the worst-case scenario, the extra info should only be worth a small fraction of the sidepot.

Since seat 3 never really did anything wrong (its not his fault somebody exposed cards to him), it would suck to punish him.

However, in the end, my gut tells me its easiest to just say that if somebody exposes their cards to somebody involved in a hand, those cards immediately ought to be exposed to every player at the table. I'd like to make room for exceptions, but I generally don't trust floorpeople to have enough knowledge of the games to make the right subjective calls.
