There looks to be a couple of "solution" moves in the set, so some of the
positions may not be equal. Now, I recognize those draws where the engine says
+177, +177, +177 ply after ply. But where there is a sudden change for the
better and it keeps improving, makes it seem that the position is not balanced.
For instance, these two:
15) 0 1

It would seem odd to have a tournament based on positions that are won for one
side or the other.
Some of the others are apparent draws that give engines a wood-counting
headache.
