Average centipawn loss

Irrespective of the primary means of evaluating the strength of the two relative positions in a single game of chess viz.

Average centipawn loss is one of the key benchmarks, though it does take a little extra analysis for it to make sense from a human perspective. This is more in line with how computers evaluate chess positions rather than our typical understanding of play: though we do have a direct correlation in the value of pieces and pawns, positional errors are tougher to quantify with this metric for the human mind. As chess players continue to improve, the average centipawn loss continues to drop at all levels of play. However, there are clear differences between various levels of competitors. For the best human players in the world—meaning Grandmasters and super-Grandmasters—an average centipawn loss between 20 and 10 is to be expected.

Doesn't it depend on the game? If you play games that end early, you can get a lower centipawn loss by virtue of simply not having mistakes in the endgame. Also, do you mean opponents "are" or are you talking about one opponent? I see a mix of wins and losses in your recent history. That tells me there should be some higher centipawn loss games by your opponents. Maybe you resign later than your opponents, so their same centipawn loss is averaged over more moves. For example, if you play a lot of weaker opponents, it is going to be easier to find the best move and capitalize on their mistakes, and so you will have a lower cpl. Your opponent might have trained himself to play the sort of moves the computer likes. That's quite possible. The onboard engine is only any good with fairly immediate tactics. If all my moves were the same as the engine's, I would assume I wasn't playing well. The engine's assessments can't be trusted. I can think of a few games where, if I'd played the engine's moves, I wouldn't have won because the engine line was drawn by force. Why choose median over mean?

I can think of a few games where, if I'd played the engine's moves, I wouldn't have won because the engine line was drawn by force. I've tried to average centipawn loss higher-order polynomials of aCPL as predictors 2nd and 3rd degreebut as you might have guessed given the scatterplot above, this was not helpful there simply does not seem to be much of a relationship between aCPL and rating, average centipawn loss, of any form.

Many chess players do not understand the unit of measure known as centipawn. For club players, understanding the term is not too important; however, understanding what it means may be helpful when reading game reports or reviewing game analyses. Here is what is important to know:. A centipawn is a measurement unit to calculate the strategic features of a position in a chess game and determine which player has an advantage, although this measure has no formal role in a game. Several evaluation systems incorporate the use of centipawns. Because pieces have integer values in pawns, determining an advantage less than a full integer requires fractions.

This article is part of our World Chess Championship series. Magnus Carlsen of Norway continued his unrelenting march toward the world chess title on Wednesday, holding his challenger, Ian Nepomniachtchi of Russia, to a quiet draw over 41 moves in just over two hours. With a 6. After yet another beginning in the Petrov opening , both sides safely and quickly steered the game toward peaceful pastures. The game was a respite from the disasters that shook the previous two games, in which Nepomniachtchi blundered a pawn and then a bishop, respectively, losing both and ceding any realistic hope of becoming world champion. As someone who once blundered about six times versus Carlsen in a single game , I empathize. After 10 games, this has been a tale of two matches, featuring both the impressively precise and the inexplicably misguided. By one measure, this year has seen the three most accurate games in World Chess Championship history; it has also seen the th, th and rd most accurate games.

This post was originally published on my original chess blog Chess Village. I have had the idea of trying to derive a player's rating "empirically", through their play rather than through their results as is currently done. As a starting point, I thought that it might be possible to approximate a player's rating by looking at their average centipawn loss. The average centipawn loss aCPL is the amount by which a chess engine's evaluation of the position changes after each of the player's moves. I thought that perhaps stronger players would have a lower aCPL, such that it would be possible to approximate a player's rating from their aCPL. To investigate this question, I downloaded one of the databases available on lichess.

For example, if there is a mate in 10 somewhere and you took a route that leads to mate in 12, you lose some centipawn there. Forgot your password? Latest article.

Now that the data are ready for analysis, I looked at some descriptive statistics for the variables of interest, the white and black ratings and aCPL. Here is what is important to know:.

The centipawn loss calculates the drop in engine evaluation after each of your moves. Say you play a move lowering the position assessment by 0. The total loss is averaged over all moves in a game.

The search for a better method continues. Results are slightly different for white and black players, such that it's slightly easier to predict a black's player rating from their aCPL than it is to do the same for a white player in these data anyway.
