I think that the moral of the story is that TD's must have house dealers to make proper rulings.
I remember that Rob (Nightfly) would not give rulings in player(punter) dealt cash games in Gala Notts.
Not a bad judge imo.
but not for a tournament surely?
besides the venues charge fees, part of that must involve TDing where necessary
(and dealers too, in an ideal world hence the a\bove argument would be moot)
