Lucas Chess – play and train chess

Chess is a recreational and competitive board game played between two players. It’s a very popular game, played by millions across the world, in clubs, online, by correspondence, and in tournaments.

The game is played on a square chessboard with 64 squares arranged in an eight-by-eight grid. Each player controls 16 pieces, and the object of the game is to checkmate the opponent’s king.

Chess has the virtue of being suitable for people of all ages. It has many positive attributes helping players develop their memory, improve and enhance their concentration, as well as enhance logical thinking. It also promotes and improves imagination and creativity. Chess is one of those games that takes a few days to learn and the rest of your life to master, with the game being a never ending learning process, even for the top players.

We tried Lucas Chess a couple of years ago, but failed to compile the program in Linux. It was disappointing because testing the program under Windows demonstrated the quality of the software. The situation has recently changed with the first official binary version of Lucas Chess for Linux.

Installation

With the release of a binary for Linux, installation is now trivial.

Download the file LucasChessR125a_LINUX.sh from the project’s GitHub repository. It’s not a small download; 262MB to be precise.

The downloaded file is run from a terminal with the command:

$ sh ./LucasChessR125a_LINUX.sh

The following dialog box should pop up. You’re given the choice of installing the software, or to play the game without installing.

Lucas Chess - Installation

If you choose to install, the software is installed to ~/LucasChessR, and a menu entry is added.

    1. I’m using Linux Mint 22 on a 2018 ThinkPad. I d/l’d the file to my download folder, opened the folder and opened the terminal window as instructed. Note I have NEVER used command line since Win95 and DOS days so Linux commands are unknown to me and must trust your word on how to do this (and why should ANYONE have to use command line to install a GUI prog in 2022 anyway???). The command line begins (in yellow) “ven@nilla-TPad:” then there is (in white) “~$”. I cut and pasted your command: “$ sh ./LucasChessR125a_LINUX.sh” and error returned: “$: command not found”. Since the paste resulted in two “$ $” showing (and DOS would’ve failed to execute that), I repasted and removed the 2nd $. Error: “sh: 0: cannot open ./LucasChessR125a_LINUX.sh: No such file”.

      I have no choice than to call you on your install instrux. They are faulty or incomplete. I then tried to double click on the file, as I would do in Windows or MAC OS to setup a new program. Instead, Linux started the text editor and tried to load the entire code to the screen as a text file. System freeze. Sheeze… really? I want to play Chess, not embark on a course in Linux command syntax and file structure. Did that 35 years ago for DOS and not again. If Linux is to get more than 1-2% of the market this “stone knives and bear skins” (-Spock) stuff has to stop. Make executable install packages and Linux will thrive!

      1. I honestly don’t understand what the issue is. Typing a couple of simple commands in a terminal emulator is exactly the same as typing text into a web browser.

        The developer has made it very easy to install;

        1) Download LucasChessR2_04_LINUX.sh (for X11) or LucasChessR2_04_LINUX_WAYLAND.sh (for Wayland).
        2) Start a terminal emulator e.g. gnome-terminal
        3) Navigate to the directory where you downloaded the file (using the cd command at the shell prompt), cd stands for change directory.
        4) When you are in the directory where you downloaded the file, issue the command in the terminal emulator:
        sh ./LucasChessR2_04_LINUX.sh (if you downloaded the X11 file)

        Then it’s a nice graphical installation.

        If you get an error saying no such file, then you are not in the correct directory or you downloaded the Wayland version.

        If you can’t work out how to get into the directory where you downloaded the file, that’s really not the developer’s fault. But it will probably be in your Downloads directory. The ~ character is useful. If you type

        cd ~/Downloads

        that will probably get you to the directory where the file was downloaded.

  1. @ Jo Nixon Pychess is available as deb package on Ubuntu, so it should be available on Linux Mint as well. It is unfortunate that the Lucas Chess author has not provided an easy way to install the Linux version. Highly recommended is Lichess dot org. Free of charge, open source, no ads. You can play against Stockfish or against another human. Has lots of training material, and you can watch others play chess.

    1. The developer of Lucas Chess has provided an easy way to install his software. It seems you think the only easy way is to provide a deb package. But his way involves typing a couple of commands, and works for all distros, not just Ubuntu/Debian or other Debian-based distros.

      I would much prefer developers focus on their software than try to write packages for the multitude of distros. Sure he could do an AppImage, snap etc, but why should he?

      Lucas Chess is fair superior to Pychess, or Lichess.
