TN or theoretical novelty generally means a move in the openings which
is being played for the first time in grandmaster play. Grandmasters
and masters spend a lot of time trying to come up with TNs to spring
on their opponents. Nowadays they are all analyzed and played by
computers before the grandmaster plays it over the board against a
live opponent.

Chess Informant defines a TN as a move which which has never appeared
before in a previous edition of Informant.

A TN (theoretical novelty) does not have to come about in grandmaster play and
has nothing to do with Chess Informant. A TN can be played by anyone and does
not have to be published in the Informant.
Perhaps Hooper and Whyld define the term best in The Oxford Companion to Chess
by stating that it's "a move in the opening which is thought not to have been
played before." A TN could be played by an amateur player and never see the
light of day in print.

I do not believe that the definition can go that far. Otherwise, every
beginner's game would be a theoretical novelty. I agree that a
theoretical novelity does not have to be played by a grandmaster. A
master or even an expert could play one. However, the move would have
to be in a position known to chess theory and played by a person who
has studied that theory. For example, every tournament game I play
contains original moves which have never been played before but nobody
classifies my games as theoretical novelties because the openings I
play such as 1. g4 have not been incorporated into chess theory as
defined by the well known authorities on the game.

Maybe it's necessary to remember that "theoretical novelty" has two
words. The first one mean your move need to be interesting for chess
theory. In 1.e4 e5 2.Nf3 Nc5 3.Bb5 a6 4.Bxc6 the move 4...h6 will not be
a TN if that move is not interesting for theory. (and I think that not
depend on to be played by a GM (maybe a mouse slip) or to be published
in C.I.
