Enter a Chess.com or Lichess username to analyze a player’s recent game history: win rates, openings played, accuracy trends, and recurring mistake patterns across bullet, blitz, and rapid.
Chess Ramp also estimates playing strength from engine-scored accuracy, giving you a performance breakdown that goes deeper than a rating number.
The openings report shows which systems a player actually reaches and how they score in each — useful both for finding the leaks in your own repertoire and for preparing against a specific opponent before a match or tournament game.
Trends matter more than snapshots: seeing accuracy and results broken out by time control makes it obvious whether your blitz habits are leaking into your rapid games, or whether a rating plateau comes from openings, tactics, or time management.
