Unlike cheaters, the strongest grandmasters of the World make quite a lot of mistakes.
http://kasparovserchess.blogspot.com.by/2017/04/unlike-cheaters.htmlWell, without reading it all I would say it depends very much on the position. I had some games with as many errors as moves and some virtually without any (0/0/0).
en.lichess.org/WWp3CAawMost of games by Carlsen in classical time controls are 0/0/0 like the recent one against Fabiano.
If I remember correctly the first game of the wcc where Carlsen played the trompowsky it was 0-0-0 with like 8 combined acl. Something like 4 each.
Yeah, the game above is 7 acl combined.
If I was a conspiracy theorist I would say that when draw benefits both players they let tweaked chess engines play against each other, then if it's a draw they memorize the game and replay the game OTB. But I really see no point in that. Probably they got so good by training with help from engines.
I wonder if they can draw strong engines. When playing blitz the engine punishes every inaccuracy/mistake/blunder, but in classical, where they are able to play these 3-4 acl games?
When two grandmasters both want a draw, then they play a draw, they do not have to memorize anything for that.
It is easy to get low AcPL when no player takes any risk, just develop pieces, trade pieces, go to drawn endgame, draw, no mistakes.
Kasparov could not keep up with the engines.
Anand says he lost to computers, now to phones and soon will lose to his refrigerator.
The engine provokes the mistakes by going for sharp variations.
