I've been a bit obsessed with chess lately and have read/heard things like "X is the top engine move, but no one under master plays that line". To me this begs the questions "which line are players below master playing" and "which line are players at/above/below my rating playing". So I built a tool to analyze the move distribution (win/draw/loss rate) from a given position across ratings (400, 600... 3000).
