A new file called data/eco/openings.csv should be created and populated with chess opening names, ECO (Encyclopaedia of Chess Openings) codes and movetexts.
This file is intended to feed the database's eco table.
See:
Keep it up, and happy coding and learning.
The default script should be renamed to cli/data-prepare/training/classification/start.php. This one is intended to play games from the start position rather than from a FEN position.
There will be two scripts preparing data for further training:
cli/data-prepare/training/classification/start.phpcli/data-prepare/training/classification/fen.phpSee #1
A new table called inbox needs to be created by the cli/db-create.php script.
| Field | Type | Description |
|---|---|---|
hash |
string | The unique hash of the game |
variant |
string | 960capablancacapablanca-fischerclassical |
settings |
JSON | Optional settings: Initial FEN string |
fen |
string | The current FEN |
movetext |
string | The sequence of PGN moves played |
createdAt |
datetime | The creation date of the record |
The MySQL inbox table is intended to store the information required by the correspondence chess functionality and will eventually replace the SleekDB database in the chess server.
Example:
{
"hash": "cace2a000275f8ee8558a3b69b77efa2",
"variant": "960",
"settings": {
"fen": "qnbbrnkr\/pppppppp\/8\/8\/4P3\/8\/PPPP1PPP\/QNBBRNKR b KQkq e3"
},
"fen": "qnbbrnkr\/pppppppp\/8\/8\/4P3\/8\/PPPP1PPP\/QNBBRNKR b KQkq -",
"movetext": "",
"createdAt": "2024-01-21 11:31:22",
"createdBy": 1662,
"_id": 4
}Happy coding!
After the database has been updated with recent TWIC data, the JSON files in redux-chess/src/assets/json need to be recreated accordingly for the frontend. See #19.
A new table called openings should be created and populated with chess opening names, ECO (Encyclopaedia of Chess Openings) codes and movetexts.
| Field | Type | Description |
|---|---|---|
| eco | char(3) | ECO code |
| name | varchar | Opening name |
| movetext | varchar | Movetext |

At the present moment, there's only this script to prepare data for further training. It can play entire games from the start position, however, a new script should be added specifically for the purpose to play games from FEN strings.
The new script will allow to prepare data from rook endgames for example. More specifically, the next step in this machine learning project is to teach the computer how to deliver checkmate with a king and a rook only, and it is for this reason that the data/endgames folder has been created today.
The new script that prepares data from FEN positions should be named cli/data-prepare/training/classification/fen.php
Keep it up, and happy learning and coding.
Let's teach the computer to play chess by example!
This issue is intended to create the necessary data that will be used to teach the computer to deliver checkmate with a king, a bishop and knight against a lone king.
As described in Add a new script to prepare data from FEN positions #1, a new script which will prepare games loaded from FEN positions is about to be created. However, despite this data preparation script not being added to the codebase yet, the data for further training can be created at this moment.
Thus, a few endgames that will force a checkmate should be played at this stage of the development, for example:
Today, ten examples of King and Rook vs. King have been added in the data/endgames folder, and the exact same thing should be done for the endgames listed above.
Keep it up, and happy learning and coding.
Files available in the TWIC archive should be downloaded into the data/twic folder.
Keep it up, and happy coding and learning!
The demo database available at https://chesslablab.com contains more than 500,000 games available for study for free.
However, names of chess players may be duplicated and are sometimes unclear.
Figure 1. Viswanathan Anand?
Figure 2. Zsuzsa Polgár?
Figure 3. Gary Kasparov?
Find out a way to be more specific about searching games by player name and remove duplicates so that searching data will be easier.

This issue is intended to create the necessary data that will be used to teach the computer to deliver checkmate with a king and two bishops against a lone king.
As described in Add a new script to prepare data from FEN positions #1, a new script which will prepare games loaded from FEN positions is about to be created. However, despite this data preparation script not being added to the codebase yet, the data for further training can be created at this moment.

Find out why the following TWIC games won't be loaded into the database.
$ docker exec -itu 1000:1000 chess_data_php_fpm php cli/seed/players.php data/twic/twic1460.pgn
✗ Whoops! It seems as if no valid games were found in this file.
$ docker exec -itu 1000:1000 chess_data_php_fpm php cli/seed/players.php data/twic/twic1461.pgn
✗ Whoops! It seems as if no valid games were found in this file.
$ docker exec -itu 1000:1000 chess_data_php_fpm php cli/seed/players.php data/twic/twic1465.pgn
✗ Whoops! It seems as if no valid games were found in this file.

At this moment, a chess server is running on pchess.net — a micro instance on AWS EC2 — which is the sandbox environment for development and testing, however, this instance can be used to host a chess database as well.
Two services should be running on this machine:
This issue is about creating and populating a database with the grandmasters games in chess-data/data/players/ as per the docs.
Keep it up, and happy learning!
Files available in the TWIC archive should be downloaded into the data/twic folder.
