If you are running a tournament where players there are 10 seat tables then your final table should be formed with 10 players as usual.
If 6 seat tables, then the final table should be formed with 7 players.
The "Hand for hand" way is exactly the answer. Dealers start to deal together, if action on a table is still pending, and the other has finished, then this one must stand by and wait. If a player got busted from the table with action, trhen a Final table is formed, a new hand starts otherwise
