Let’s Check Engine Correlation: How to use it

The Let’s check The job began as a way to distribute computer analysis of games or situations to other users and not just get feedback from one engine, but as many as three. This was your “scratch my back and I’ll scratch” process because you spent credits to get this, and you earned credits by leaving your device unlocked for others to order the same from your computer.

The most recent addition to its functionality has been to provide a report at the end of the analysis, displayed at the beginning of the blogging, to let you know about motor connection The degree of both white and black. this is motor connection It is a summary of the number of moves that matched the best engine choices. If all the movements match the first option of the motor, then the file motor connection The result will be 100%.

Why use let’s check engine correlation?

Imagine you’re analyzing with only Stockfish, and it says five out of ten moves are not identical. This may overlook that two of the moves that don’t match her choices are chosen by another main engine like the Komodo Dragon 3. In other words, only five of the Stockfish match, but seven in all of the top matching engine choices. This is the main point of Let’s check the motor connection. When you analyze a game using it, not only will it tell you what a variety of engines thought of each move, it will give you a summary called motor connection At the top, it shows the percentage of times a player’s moves match the top mover option.

However, unlike a normal motor comparison, you will not compare with just one motor movement, it will be compared with many ofand if the motion matches any of those motors, it will be identical to motor connection.

Engine linkage in ChessBase 16

If you have ChessBase 16 or later, you can access the pure report with a complete average summary from multiple games. To access it, highlight one or more games in a database, right-click and select Edit and then at the bottom of the list select Let’s check the motor connection.

No matter the number of games, you will get an overall performance for all players. For example, after being asked to report on all the games and players from the 2022 Candidates Tournament. Nepomnyakhchi stomped across the field admirably and motor connection He agrees with this by showing how his level of moves corresponds to that of the best movers.

be cerfull: Not only will it ignore any annotations that are already in the game, but it will erase them and replace them with Let’s Check annotations.

You will notice two things in the image above. The first is that Nepomnyakhchi’s score was 12% higher than any of his competitors, which is a huge difference. The second is that although each player played 14 matches, many of them scored only 12 or 13 matches.

The reason is that Let’s check will ignore common theory moves, and motor connection It will not be reported if too few moves are analyzed in the game. Let’s say the game was 28 moves in length, but 20 of them are rated as theory, meaning it only has eight moves to rate already, which is too few to be able to report.

If we open a game form, we can see a report at the beginning.

Engine connection in Fritz

If you use any of the chess engines that use an updated version of the Fritz interface, such as Fritz 18, Fat Fritz 2, or Komodo Dragon 3, you have some advanced options open to you.

Getting to it is just having a game in front of you, then going to Analytics Menu and left selection Let’s check the analysis.

Unlike ChessBase 16, this will open a new pane with options.

The first option is Bugs, combinations and training, which you will analyze by looking for the missed movement so that you can test yourself against it. The second is return only It is cloud-only consulting for in-game functions that have already been analyzed by other users. This will actually get a file motor connection Report if enough moves have been analyzed before.

Then we have the most interesting option: Standard Analysis. The standard word is usually not the kind of words associated with “interesting”, but you’ll see why.

Let’s press advanced.

Now we have a number of options to play around with. The key to understanding here is this: Now when you are accessing a file Let’s check Moving on, you will also use your engine to contribute to further analytics. For example, if you select Just the different moves, then every time a movement in the game has not been chosen by other engines, it will be analyzed using your engine and the results will be added to the database. This will happen even if the result is consistent with other engines.

Read results

As we mentioned in a previous article, the best players are fully capable of 100% matches, 90% multiple hits, or better results. And even a much weaker player can sometimes make a high match, so don’t read too much into a few isolated high scores. I present one of my own games that I played a few years ago:

As you can see, I had an 86% match rate, however that means very little other than that I was having a good day at the time.

There are those who say that this type of result does not mean that the player was playing better, but simply that they were playing more motor moves. However, I present to you that if the engines are all 1000 Elo or better than us, finding the same moves will definitely indicate that you also made moves that are much closer to perfection than not.
