  1. Hi Lucas,
    terrific work!

    Usted merece una estatua!
    (have i written it right?)
    On my first quick try, I'm having these problems:
    "Determina tu potencia de càlculo" and "Comprueba tu memoria sobre un tablero"[they freeze when the message "Un momento por favor" is showed on the screen]
    Kind regards,
    Stolcius Von Stolcenberg

    1. Thank you very much,
      I have tried to fix them.
      A new distribution is available.

  2. Tnx, Lucas: fixed! :-)

    I've spotted another little bug.
    After having analyzed a game, i click on "Show graphics", but nothing happens.

    Best regards,

    1. When "Show graphics", program creates a html file, then say to OS to open this file with the default program, and this is usually the default browser.
      File created is histoA.html in the html program subfolder.
      Can you read this file with browser ? or are html files associated with default browser in your PC?

    2. Solved: the problem was with my browser configuration.


  3. Hi, Lucas,
    Adjourn function doesn't work with "Elo Ratings" & "Training Ratings".
    - I push the button
    - LC shuts down
    - At restart the chessboard is empty and frozen

    Bug.log is empty
    On the other hand, with "Play against an engine" it works correctly

    Best regards,

  4. Lucas, thank you for your excellent work. I have a question. How can I add my pgn positions for the my analysis in training "determine your calculating power".

    1. It is not easy to add.
      I add your suggestion to the pending list.

  5. Lucas добавить функцию "сеанс одновременной игры"

    1. Hi Husniddin, I have not forgotten your suggestion about simultaneous chess games, it is pointed in my list.

  6. Amazing program; just keeps getting better! Thank you!!

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
