Analysis: average centipawn loss and graph
Sort:
Chessbase article on the subject: LINK
Apparantly nobody are using it? Does anyone wish to use it? Seems that it may become a more integrated part of future analysis software. Chess-db.com seems to be using a similar feature named "play quality index" which they are calculating of all of their games: http://chess-db.com/public/research/qualityofplay.html
First improve your planning ability. Drop the style of engine. It can not teach you chess.
Lucas Chess gives you those two things and a lot more.
Hi earth - thanks for replying. I agree with you as my main source for getting better at chess has nothing to do with computer engines. I do however also love statistics, tracking my development, comparing to other (and better) peoples games etc. I cannot see why it should be a problem to have an extra handy resource for this kind of thing.
E.g. I got the analysis numbers of one of the Carlsen/Anand-games where you can see that their average centipawn loss (ACL) are extremely low compared to most others (as one could have guess'ed): LINK. Carlsen are playing with an ACL of only 4 and Anand are right behind with 5.
I'm confident that it is possible (with correct factors counting in) to evaluate say 10 games with something like this and get a close estimate of ones playing strength - like you can also tell how you performed in a single game (according to "perfect-computer-moves") instead of "just" relative to your opponent.
Chess-db are claiming a very close relationship to registrated player elo strength in their own analysis of their sample of pt. 50,000 games when using their own interpretation of this tool (play quality index):

Cool. Do you use this average centipawn feature and do you think it gives a good overview of playing strength over some few games?
Guess Lucas Chess is only for PC and not Mac?

Yeah, I glance at it sometimes. It has as much to do with how easy your opponent made it to find the best moves as your ability to find them. Lucas Chess is probably for PC only, though I know there was some attempt to port it to linux recently, so there may be some way to make it work for mac. No idea.
Lucas Chess doesn't throw out the huge differences in evaluation like lichess and the thing in the chessbase article mentions, I don't think. That makes it a touch less useful for me. The problem with lichess is it's quick, superficial analysis. With Lucas Chess you can set it to whatever time/depth you want.
Thanks for sharing the screenshots. I can see that Lucas Chess do factor in the complexity of some sort (if it affects the ACL-score). I wonder how it does it - but i guess its possible to find out via some Lucas-manual.
Lots of info about that stuff:

Thx - i will have a look.
Lucas Chess (free here: http://www-lucaschess.rhcloud.com/index.html) does a similar graph plus indexes. Here's the summary page I cut-and-pasted from a recent game here (Black vs Hamlet Alexsanyan 4.1.17). There are tables for each move (Tabs All moves, White, Black). The solid line on the game board is the move I made at a certain point that I clicked on the All moves page to examine in the game and the dotted line is the one Stockfish 8 likes best (set to whatever ply you like):
I'm sorry if you can't run Lucas Chess on a Mac. I know there's also a Linux version - can you run it through a Linux emulator?
Hi Mick - thanks for finding this old thread of mine a few months ago. I have a Windows computer now and enjoys Lucas Chess and its stats. However, like the Chessbase article points out, you have to cap the max point loss (low rated players - don't cap too much, high rated players - don't cap too little) in the settings to avoid unreasonably high penalties for gross mistakes.
I just tried analysing a game and to my great pleasure it spits out two things that I have been seeking for and which unfortunately are not a part of Hiarc for Mac: a graph of the score for white/black and "average centipawn loss". The graph just gives a quick overview of the state of the game over time but i guess the centipawn no. tells something about the consistency of play of both players. Anyone here that use this or similar feature for analysing/overview? Does any software contain these tools?
