    1. Hi,
      Playing against any engine: Initial moves tab, Start position.
      Tools, Create your own game, Config, Start position.

  3. Hola Lucas:
    ¡Excelente programa! ¿Existe la versión 10 para Linux?

    1. La estoy desarrollando sin pensar en Linux, así que no es compatible inicialmente, necesita algo de trabajo de adaptación.

    2. ¡Qué lástima! De todas formas estoy usando la versión 9.08a en Linux y funciona muy bien. Gracias por esta gran creación.

  4. good day Lucas,
    I want to analyze a finished game. I went to utilities then click analyze. In the general options, there is the "Depth". What is that? And then in the Brilliances, there is the "Minimum Depth" and "Minimum Gain Points". How important are ,those? Normally, I just analyze my games without touching those things.

    1. Depth: to indicate the engine fixed number of moves to eval.
      Minimum depth: to consider a brillancie, it is necessary that the engine thinks that this is the best move when it has reach this depth, not previously.
      Minimum gain points: min points to consider this as brillancie.
      They are important to extract brillancies to a file.

  5. The Lucas Chess GUI is an awesome program, and it just got better!!! I picked this as the #1 UCI-Compatible Chess Program in my article/hub...

    Continue to be awesome...

    1. Thank you very much for the article. In relation to the impression of a score sheet is not complicated to implement, I write it down, and when I have time I try to include.

    2. Welcome! I don't physically write my chess moves down, because I am unable. I have cerebral palsy and cannot write fast nor clearly enough for it to be practical. However, I do have a USCF certified electronic scoresheet that I use, and I can print it out using chessbase reader 12, which is free. So it's an important addition, I still use Lucas Chess GUI much more often than any other chess program.

    3. Ethan send me a template (by example the USCF certified electronic scoresheet if this is legal or that you consider better) to work on. And to my email: lukasmonk at gmail.

  6. I would like to say that this blog really convinced me to do it! Thanks, very good post.

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.
