Is the dealer expected to stop dealing if all players at a table are sitting out? Does this behavior differ depending on the type of game? MTT / Ring Game / SnG?
I don't have much experience live, so these answers only apply to online poker, but I believe the answer should apply the same either way.
I'm not sure how this works in ring games, I assume that there is no dealing while everyone is sitting out.
Tournaments and SNGs are different. Players can't truly sit out, as they can in a ring game. The deal continues, with blinds and antes being taken from the players, as necessary.
