  1. great, I do not know a better program to train my chess skills. I love it. Danke

  2. Hi, first of all sorry for my english :). I tried your program from version 6.1 and must say it's very well done! In version 6.2, for some strange reason, i can't start a new game when the first is ended. I click new game, beginner and simply it does nothing.

    Another question: there is a way to make the tutor think before i made my move instead of after?

    Thank you for your work!

  3. Hi Francesco, can you send me the file = bug.log (to lukasmonk at in the program folder, I can´t replicate the problem.

    And in relation to another question, there is a bug, it must think before, I will solve this and i will upload a new release.


  4. Hello Lucas!

    It could sound strange but I am interested if it is possible to fix the bug "ConfigMotor instance has no attribute 'url'" manually without downloading full installer of version 6.2a?

    Anyway many thanks for great and useful software!

    1. Download this file, and execute it in the program folder.
      It has two files lucas.exe and
      You must replace the files with the same name.


  5. Just noticed now I can't create new profiles when start Lucas Chess. I can only choose one of two I have created before. I believe were was extra menu item like 'Add new user...'

  6. When you select main user, click on Options, Other options, Users.

LINUX - First binary version

The first official binary version of Lucas Chess on Linux has just been released. It has only been made possible by the great work done by Laudecir Daniel , choosing and compiling the 67 engines, as well as laying the groundwork so that the binaries can be more widely used and others such as shortcut creation, installation scripts, ...... In addition,  Graham O'Neill  has provided Linux-specific drivers for several digital boards. This version has two limitations : 64-bit Linux OS only. Minimum GNU libc version: 2.26 (ldd --version shows it) Installation has been made as simple as possible: The installer is a .sh file, generated with the  makeself  tool, and can be downloaded from: SourceForge , GitHub The file must be run from a terminal with user permissions only: sh ./ Launches a GUI with very basic options: Install: Installs in LucasChessR folder inside the home user folder. Generates a shortcut in Applications > Games Launch the application at the end

R 1.06 Maia

 This update contains a major improvement with the inclusion of Maia. Maia is a neural network chess engine, created with the purpose of making her movements as human as possible. The Maia creation team has prepared 9 versions, from 1100 to 1900 of elo, and thus they have been included in Lucas Chess. You have all the information about Maia at:

Version R

New version of the program. Continuist at user level with the previous one, but with great internal changes. This new version has been mainly tried: Update the code to a current version of the compiler, from python 2.7 to python 3.7 (based in a previous work of Alfonso Solbes). Update the graphic library, from version 4 to 5 of qt, via pyside2. Improve folder organization, with Linux support in mind. Negative consequences: It is incompatible with Windows XP. The data is not compatible with previous versions of Lucas Chess. The weight of the installer has doubled, currently around 120 Mb and the disk installation occupies 338 Mb.
