New analysis
What are your games costing you?
Enter a chess.com username to download its game history and run the analysis: an opening win/loss breakdown over everything you have ever played, plus the tactical patterns the engine keeps catching you with.
Opening win/loss stats always cover your entire history (cheap — just PGN headers). Engine-based tactic and blunder detection only covers the number of most recent games you pick above, kept small by default since it's the slow part; raise it for a deeper but slower pass.
