Version 10.01: three bugs fixed

  • Tourney elo, the personalities don´t appear. (detected by nalbouki and PeonPasado)
  • Transsiberian Railway, some problems in the end game training (detected by Will H.)
  • The update system is not working, there is not option to pass from 10.00 to 10.01 via Information/Search for updates.


  1. Moves announcement.
    I do not know if this is the right place to ask,in case let me know.
    One question about sounds / Move announcements. I have been using version 8 and had been able, following some previous instructions now lost, to download a complete set of sounds/move announcements, so that the program was automatically announcing my and opponent's moves. Now, changing version, I have completely lost this feature and the relative sounds. Somebody can suggest me again where these sounds are downloadable and where to install it ?
    Thank you and best compliments about the program

    1. When the program is installed the folder UsrData, where all this information is saved remains intact.
      This folder is installed in the same folder than LucasChess binaries.
      The correct way to reinstall the program is to let the installation program to do all work.
      I don´t know if this is the problem.

  2. The personalities still based on Greco Lukas?

    1. Yes, personalities based on RodentII is still preparing.

  3. ¡Hola Lucas!
    Estoy tratando de instalar la versión 10 en Linux y se me presentó este problemita luego de compilar satisfactoriamente LCEngine e irina:

    Traceback (most recent call last):
    File "", line 40, in
    import Code.Init
    File "./Code/", line 13, in
    from Code import Procesador
    File "./Code/", line 5, in
    from Code import Albums
    File "./Code/", line 5, in
    from Code import Books
    File "./Code/", line 7, in
    from Code import ControlPosicion
    File "./Code/", line 1, in
    import LCEngine
    ImportError: ./ undefined symbol: movegen_piece_to

    Al parecer faltan las referencias a irina. ¿Me pudiera dar una idea de cómo solucionar esto?

    ¡Como siempre gracias por su magnífico programa! Reciba mis saludos

    1. Tienes que incluir la librería en el raiz, junto a
      Prueba y me dices si sigue sin funcionar.

    2. Hola:
      Probé copiando en la raíz pero me da el mismo error. Un detalle es que en el makefile de irina la biblioteca se generaba como libirina.a en vez de .so, lo cambié pero da el mismo error a la hora de ejecutar Lucas.
      ¡Gracias por su pronta respuesta!

    3. Prueba con un lanzador por ejemplo:
      export LD_LIBRARY_PATH=.

    4. Creando el lanzador da el mismo resultado. Tengo que investigar un poco más el tema... Me da la impresión de que se está enlazando estáticamente con ¿Pudiera ser que la referencia movegen_piece_to no está declarada "extern"?

    5. Con ese lanzador funciona en un Linux-Mate, instalado en una máquina virtual (que supongo que es lo de menos).
      Quizás tengas que añadir al PATH el "."

  4. Can't download Grandmaster files in section "Play like a Grandmaster"

    1. Yes, I´ll try to publish 10.02 next week with this problem fixed.

  5. This comment has been removed by a blog administrator.

  6. can't get dgt board to work with this version

    1. Can you tell me where is the file DGTEBDLL.dll in your system ?
      I need the path, something like "c:\Program Files\DGT Projects"
      Also you can copy this file in the LucasChess folder.

  7. 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:

Setting analysis parameters

Since version 2.04, you can change the parameters used by the program to determine whether a move is good or bad and also the elo calculated for an analyzed game. The parameters are as follows: limit_score Default value: 2000 Minimum value: 1000 Maximum value: 4000 Data type: integer Determines the score in centipawns from which the position is considered to be totally won, that the probability of winning is 100%. curve_degree Default value: 50 Minimum value: 1 Maximum value: 100 Data type: decimal percentage Expresses the correlation between the score in centipawns and the probability of winning/losing. It associates -limit_score with 0 and +limit_score with 100. Curve formula created based in  python-chess/Engine/Score/wdl    difmate_inaccuracy Default value: 3 Minimum value: 1 Maximum value: 99 Data type: integer If the difference between the best move and the move made means going
