True Score shows the practical win rate for a chess position at your rating level. Unlike engine evaluation (centipawns), True Score tells you what percentage of games you would actually win from this position against opponents at your level.

How is win rate calculated?

Win rates are calculated from millions of real games played on Lichess, filtered by rating range. We use Bayesian analysis to provide accurate win/draw/loss probabilities for each position and move at your specific rating level.

What rating should I use?

Use your Lichess rating. If you only have a Chess.com rating, Lichess ratings are typically 200-400 points higher. TrueElo is optimized for players rated 1200-2000 on Lichess (roughly 900-1600 on Chess.com).

Yes, TrueElo is completely free to use. There are no accounts, no subscriptions, and no premium features. All analysis runs in your browser with no data collection.

What is a Sharp position?

A Sharp position is one where your move choice significantly impacts your winning chances. In Sharp positions, playing the best move matters more. TrueElo highlights these so you know when to think carefully vs. when any reasonable move is fine.

How do I build an opening repertoire?

At each decision point, TrueElo shows the move with the highest practical win rate at your rating. Pick these moves consistently to build a repertoire of lines that you can actually convert. Focus on moves you can remember and execute, not computer-perfect theory.

Why not just use raw win rates from Lichess Explorer?

Raw win rates do not account for sample size or data reliability. A move with 60% win rate from 50 games is less trustworthy than 55% from 5,000 games. TrueElo synthesizes win rate data with sample size to give you one reliable number.

How is TrueElo different from Lichess Explorer?

Lichess Explorer shows raw statistics for each move. TrueElo synthesizes that data into actionable recommendations — showing which move you should actually play at your rating, not just the numbers. It also adds engine evaluation context and detects sharp positions where move choice matters most.
