Let's Check vs Centipawn Analysis.

Using Let's Check GM Carlsen played the perfect game with 100% chess engine matches. , and could be cheating.

This is the same evidence that is being used against GM Niemann.

But Let's Check has major flaws, and is not indication that a player cheated.

Look at move 19.e4 by GM Magnus Carlsen. Let's Check gives GM Carlsen a 100% score of chess engine matches.
Despite the fact that GM Carlsen blundered at move 19 by 1.4 Centipawns.

So how can Let's Check say GM Carlsen played a perfect game with 100% chess engine correlation.
And at the same time GM Carlsen blunder more then a pawn that any good engine will see is a blunder.

Because Let's Check is garbage.

Let's Check vs Centipawn Analysis.

Using Let's Check GM Carlsen played the perfect game with 100% chess engine matches. , and could be cheating.

This is the same evidence that is being used against GM Niemann.

But Let's Check has major flaws, and is not indication that a player cheated.

Look at move 19.e4 by GM Magnus Carlsen. Let's Check gives GM Carlsen a 100% score of chess engine matches.
Despite the fact that GM Carlsen blundered at move 19 by 1.4 Centipawns.

So how can Let's Check say GM Carlsen played a perfect game with 100% chess engine correlation.
And at the same time GM Carlsen blunder more then a pawn that any good engine will see is a blunder.

Because Let's Check is garbage.

There are certainly chess engines that play 19.e6
You may define the engines that make this move not good engines but they are certainly at least at GM level(and it may be interesting to see what is the highest rating of engines that play 19.e6 after 3 minutes of search(movei that has CCRL rating of 2665 suggest 19.e6 at depth 17 and I guess the analysis used a stronger engine than movei to get 19.e6).

Let's Check vs Centipawn Analysis.

Using Let's Check GM Carlsen played the perfect game with 100% chess engine matches. , and could be cheating.

This is the same evidence that is being used against GM Niemann.

But Let's Check has major flaws, and is not indication that a player cheated.

Look at move 19.e4 by GM Magnus Carlsen. Let's Check gives GM Carlsen a 100% score of chess engine matches.
Despite the fact that GM Carlsen blundered at move 19 by 1.4 Centipawns.

So how can Let's Check say GM Carlsen played a perfect game with 100% chess engine correlation.
And at the same time GM Carlsen blunder more then a pawn that any good engine will see is a blunder.

Because Let's Check is garbage.

There are certainly chess engines that play 19.e6
You may define the engines that make this move not good engines but they are certainly at least at GM level(and it may be interesting to see what is the highest rating of engines that play 19.e6 after 3 minutes of search(movei that has CCRL rating of 2665 suggest 19.e6 at depth 17 and I guess the analysis used a stronger engine than movei to get 19.e6).

And that is why the data is garbage. Let's check is not designed for cheat detection. Are you suggesting GM Carlsen did cheat with a 100% match. And there are more players with 100% Let's check games.

If it were up to Grandmasters to determine if other Grandmasters cheated in chess. There would only be one Grandmaster left in chess.

Another person from my chess club from years past. Where GM Niemann was accused of cheating by GM Magnus Carlsen. Who also knows the facts, and the people that are involved.





And this is why I will not go on GMHikaru's channel. I know him and the guy is a idiot. Who cares nothing about facts, only views.

Maybe GMHikaru can do a demonstration of the chess butt plug. It would get massive views.
