Chess experts are only good at remembering valid chess positions that could result from a game in play. Their "expertise" vanishes why trying to remember chess boards set up at random (invalid) positions. It could be that there are a few valid states that can be highly encoded in each of these situations, and the autoencoders found them. This could be highly useful.
