Average centipawn loss

Many chess players do not understand the unit of measure known as centipawn.

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. In the World Chess Championship between Magnus Carlsen and Fabiano Caruana, the Norwegian managed a single-digit average across the twelve classical games. A master player somewhere between and ELO might have an average centipawn loss of 30 or so in a normal game.

Irrespective of the primary means of evaluating the strength of the two relative positions in a single game of chess viz. Such that if a human player makes the best possible move for any position, they will lose 0 centipawns. The best move possible is simply the 1st choice move of the strongest engine like Stockfish 11 or 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. The GMs of today are so accurate that their games could read around below 10 centipawn loss in classical time controls and 15 in rapid time controls see: WC, Carlsen vs. Caruana, , and even above 20 in blitz. It may interest you to note that WC matches between the years and were having average centipawn loss of 30 and even 40! But in blitz time controls, even Carlsen has never attained less 15! Even against a weak opponent! In retrospect, because of the prevalence and proliferation of the chess engines, chess players all over have become more accurate; becoming like the engines they create. However, even as human chess evolve in an ultra-modern feat, the engines equally evolve; we grow and they grow even faster! Consequently, the development of centipawn, a currency we can use to compare the relationship between our move and that of the strongest chess engines. Every player with his strength is relative to the average centipawn loss expected of them.

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.

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. These databases include all rated games played on lichess for a given period. For the purposes of this exercise, I used a subset of the August database. From these games, I kept only the ones for which computer analysis was available, so that the engine's evaluation--here, Stockfish --is available after each half-move. I ended up with a total of 1, games.

Average centipawn loss

I had two games today with no mistakes or blunders and a handful of inaccuracies with less than 20 average centipawn loss. I've never done that well before. What do you consider a decently played game in terms of average centipawn loss? I also had a few games today which were total blunderfests but hey , you gotta start somewhere It really depends on the game and what your opponents acpl was. I wouldn't focus to much on it most of my favorite games have high centipawn loss due to sharp confusing positions caused by gambits and what not.

For super grandmasters, an average loss is between 20 and Expert-level players in the range likely go up to 50, with the online average player crowd seeing their ACPL stats somewhere between 50 and on a regular basis. Knowing a player's aCPL would not help us much in guessing their rating. The figure below shows the first few columns and rows of the dataset:. But in blitz time controls, even Carlsen has never attained less 15! Top Bloggers. I can't win please help me! So my overall conclusion, stated somewhat crudely: I would not use this model to predict a player's rating after having observed one of their games and analyzed it with Stockfish.

Just when you think you are getting to grips with the game of chess, improving your skills, and seeing your ELO rating, someone comes along and mentions Average Centipawn Loss and you have no idea what it is. This article will explain what centipawn loss is as a unit of measure and how it is used in chess.

New Computer Bots Lavskiy 5 min ago. Observations are relatively tightly distributed on the x axis aCPL for the full range of the y axis player rating. Feb 7, 0. As a first step I've also combined information from all moves into one summary statistic, the aCPL, but incorporating move-level information might yield better results.

Maybe you resign later than your opponents, so their same centipawn loss is averaged over more moves. I ended up with a total of 1, games. If you create a new account, the system imagines that you are and judge you at such, but as you grow over time, the system expects a lower centipawn from you.
