The engine evaluation is in pawns from White's view. Average centipawn loss measures how far your moves were from the engine's best, on average.
Key principles
- +1.0 is roughly an extra pawn
- Big swings mean tactics; slow drifts mean positional errors
- ACPL compares accuracy, not results
Common mistakes
- Treating +0.3 as a winning advantage
- Judging a move only by the eval change
