How good is a 3100 chess player?
Rates are per 100 live moves: moves played while the game is not already decided.
What the terms meanShow less
- Centipawn.
- A hundredth of a pawn, the unit a chess engine scores a position in. Giving up a pawn for nothing costs about 100.
- Centipawn loss.
- How much worse a move is than the best move in the position. The average (ACPL) counts every move a player makes.
- Blunder, mistake, inaccuracy.
- A move that loses at least 150 centipawns is a blunder, at least 70 a mistake and at least 40 an inaccuracy. Only live moves are counted.
- Only move.
- A position where one move is clearly better than every other. “Finds the only move” is how often a player plays it.
- Time trouble.
- Less than a tenth of the starting time left on the clock. “Games in time trouble” is the share of games in which a player's clock got that low on any move, however the game stood.
- Winning, better, balanced, worse.
- How the engine scores the position for the player about to move. Balanced is within half a pawn either way, better is up to a pawn and a half ahead, winning is from there up to three pawns ahead, and worse is up to a pawn and a half behind.
- +1, +2, +4.
- A lead of at least one, two or four pawns by the engine's score. A lost position is one that has fallen two pawns behind or worse.
- Percentile.
- The share of a site's players who are rated lower. Blitz and rapid players are ranked separately.
