Thanks for the link. It does confirm what I said. They all agree that in a cash game the dealer can never turn over the absent players cards. Jack Effel did say that the cards must be tabled in a tournament but never disclosed who would turn them over. I know this...when I deal, there's no way I'm going to turn those cards (of the absent player), without explicit orders from the floor!
Taking it a step further, lets say the absent player left the room, (we've had this discussion long ago), what then? I would kill the hand expose it and if it were the winner the chips could be removed from play or the pot would go to the remaining player. Because of tournament rules, I see no better solution.
