Perhaps another approach is to ignore "easy" chequer plays, i.e. similar
to cube decisions, only count the moves that can potentially be
misplayed (perhaps were the worst move is more than a certain equity
from the best move)?  This would automatically include forced plays.

This would push up the total chequer error - so perhaps then all the
ratings would need to be rethought?

I'm far from an expert in this area, so this might be a stupid idea :o)
