Lichess ratings are used throughout this dataset. If you play on Chess.com, your rating there is typically 200–300 points lower than your Lichess equivalent, meaning a 1400 on Chess.com corresponds roughly to a 1600–1700 here. Use the rating band filters accordingly.
Key patterns across 294,789 games
Each circle is an opening family, and bigger circles are played more often. The higher a circle sits, the better White scores: above the dashed 50% line White wins more than Black, and below it Black comes out ahead. Scroll to zoom, drag to pan, or search to highlight one opening.
Share of games won by White, won by Black, or drawn, grouped by the two players' average rating.
How each game finished (checkmate, resignation, flag on time, or draw), grouped by rating.
The five most played openings in each rating band. Longer bars were played more often, and the win rates show how White and Black scored with each.
How lopsided each opening is. Each bar is White's win rate minus Black's: bars to the right favor White, bars to the left favor Black, and longer bars mean a bigger edge.
Outcomes split by game speed: Bullet (under 3 min), Blitz (3 to 10 min), and Rapid (over 10 min). Always shown across all speeds for comparison.
How White's win rate changes the longer both players stay in known opening theory. The x-axis is opening depth in half-moves (ply 10 means five moves each). Each line is a rating band.
How long games last in real time. The box holds the middle 50% of games, the line inside is the typical (median) game, and the whiskers reach the shorter and longer extremes.
How many moves games last. The box holds the middle 50%, the line is the median, and the dot is the average. Stronger players tend to play longer games.
How often the higher-rated player actually wins as the rating gap between the two players grows.
