edlerman,
I'm not the one you requested but, I'd like to give my take and then we can have some issues to discuss. My call would be that no extra burn be used. The reasoning is; with the SB already skipped no one has their "proper card." I understand exactly what you are saying, and if that was a house rule, you could justify that call. I would put it in a category of "randomization" where any unknown card will give players an equal chance to win or loose. A normal deal in a cash game will skip an absent player but, in a tournament, even when we know the player won't be at the table for the current hand, we deal him in anyway, thus changing everyones cards. Good question. I hope my explanation makes sense. I don't know of any writen rule that covers that exact situation. It would be nice to hear from one of the TDA experts.
