Are you sure that Shredder had no advantage? After all, Shredder won. Perhaps
it was Fruit that misunderstood the position.
The difference in strength between Shredder and Fruit is just a few Elo, and I
consider them to be of the same strength within the level of experimental
uncertainty. I imagine that Shredder and Fruit will misevaluate about the same
number of positions, if given a large pile of them at random.
