Yes, I agree completely. That is the reason that I also think the WAC.230
answer is correct, even though it has {probably} been refuted! Optimal play
will {likely} result in a draw anyway, but it is still the *only* move that has
any winning chances. No matter how you look at it, it still appears that the
Junior move was the best one and it is the one that takes the initiative. It is
brave, bold and daring.
