I've been watching this post for a few weeks. These situations are so complicated to explain, at least I seem to have a difficult time following them when I don't see them played out...probably just my problem but here is my reply.
During tournament play, whenever multiple players are eliminated on the previous hand, and the newly added players cannot be dealt out of a hand, it is in the best interest of the game to redraw for the button.
If it's a rule...they will live with it. Besides, it's a hell of a lot easier to explain than what I'm reading here.
You could even consider eliminating the last player that just posted the BB from the draw.
Any thoughts?
