Just to clarify further.......
What these terms mean to me and what I tell players.
At your seat: Means you must be at your seat to be eligible to play a hand. <----- This meaning is generally associated with Last Card dealt to the Button (WSOP rules) and Action in Turn events.
First Card Off: Means at the start of each new hand you must be at your seat when the first card is dealt to be eligible to play a hand. <----- This meaning is generally associated with all PokerStars events and WPT's and those claiming to use TDA rules.
Some people say interchange "to be able to play a hand" and "to be eligible to receive a hand", but that is not true in tournament poker as all chipstacks receive a hand with or without a player present and that does not necessarily mean you will be allowed to play the hand.
Maybe I should be a paralegal.
