Difficulty Metric
Measuring what engines can't
Engines tell you which move is best, but not how hard it is to find. Our difficulty metric quantifies position complexity for humans, using neural network models trained on millions of real games. It powers coaching insights, move classification, and critical moment detection.
Positions that the metric labels as more difficult lead to larger errors on average, and players consistently spend more time thinking in them.
