Detailed Analysis
Evaluation Chart
Evaluation:
How good the position is, in pawns (1 pawn = 1.0). + (blue) means you are better, − (red) means your opponent is. Capped at ±10. Touch a point to see the actual value.
◆ Mate:
A position with checkmate in sight (shown at ±10). Touch a point to see the moves to checkmate (M3: you mate in 3, -M3: your opponent mates in 3).
Skill Radar
Estimated from engine evaluations. It may not match your actual strength.
How Scores Work:
For each move, the winning chance (calculated from the evaluation) before and after the move is compared; the less it drops, the higher the move's accuracy. Each item is the average accuracy of its moves (out of 100). Items with fewer than 3 moves show (-) (Tactics is scored from a single move).
| Opening | Moves 1 to 10 |
|---|---|
| Tactics | Moves right after the opponent dropped their winning chance by 10% or more (did you take the chance?) |
| Strategy | Moves other than Opening, Endgame and Tactics |
| Endgame | Moves once both sides together have 8 or fewer pieces other than kings and pawns |
| Consistency | Share of all moves that did not drop the winning chance by 10% or more |
* The win % and accuracy formulas are based on Lichess's calculations.
Win % and Accuracy
Win %:
Your chance of winning (0–100), calculated from the evaluation after each move.
Accuracy:
For each of your moves, a score (0–100) comparing your winning chance before and after the move. A move that keeps your winning chance scores 100.
