I consider text or Internet help (except Artificial Intelligence-aided
help, of course) for openings may be legal in games like Chess, Shogi or
Xiang-Qi by diverse reasons: the first is the nature of the slow-timed
Tournament, theory help can act in favour of quality, at least before the
middle of a game. The second, it reduces the advantage of very experienced
players: they can use the theory by memory, others can´t. Chess and
Xiang-Qi are very sensitive to openings, you can be considered lost, at
least in theory, even in three, four or five moves, if you fail in correct
first moves sequence. Theory exists, and people use theory by memory. I
don´t see incorrect you can use books in this class of Tournament. Shogi
is a bit different: theory exists, but the game itself is less sensitive
to bad openings. Other opinions?
