Development version 11.00.19: Director changed

Bugs fixed:

  • Find best move training, doesn't show correct moves when using a language different from english to show pieces. (Max Aloyau)
  • Order in analysis when score is over 10000 centipawns. (Max Aloyau)
  • Transsiberian, automatic save doesn't include Date field (Pedro José)
  • Challenge 101, bad score when time used is less than 5.0 secs. (Max Aloyau)
  • Transiberian, level 2, error in a tactic. (David Parkin)


  • Database added two tools to change the order of registers (TheIgnobleSavage)
  • Updated McBrain to version 2.7
  • Director:
    • Main change: graphic elements are added directly on the main board.
    • After saving a position the added elements are visible from any other board.
    • It is possible to change the file that has the information, which can facilitate sharing with other users.
    • Can be added text in a blackboard.
    • Activated with F1..F10.
    • A simbol appears in the board when the position has info.

11.00.19 -> 11.00.19a: bug fixed in the panel of results to Compete-Singular moves-Calculate your strength (thanks to Max Aloyau)


  1. Please a WinBoard/XBoard Protocols also the Engine log in Lucas Chess like arena GUI in Lucas Chess..

    1. I take note of both suggestions, I have many doubts about the first one.

  2. Fantastic chess program! Will definitely recommend...I'd like to use an external engine as a tutor. Is this possible? I checked an FAQ but it doesn't seem possible as the options when selecting the tutor are limited.

    1. Option Tools-Engines-External Engines, to add an external engine.
      Then Options-Configuration-Tutor, an select the external engine.
      The external engine must have the MultiPV option.

  3. In the Personal Openings Guide it would be useful to go up and down moves with the arrow keys instead of having to click on the move and then use the arrow buttons. Otherwise good upgrade :)

  4. Hi.
    Lucas Chess is FANTASTIC !!!!!
    But I have some doubts about ELO Performances, in analisys game.
    In the following game of mine, White (me) has a performance of 2648 Elo and Black has a performance of 3018!!!
    But the problem of an overestimation is for all my games.
    I remember that Carlsen has an ELO of 2800.
    I have done the analisys with MCbrain 2.7.
    What is the reality?
    Thank you.

    1. The elo calculated depends on the time used for analysis. The longer, the more accurate. With 10 seconds per movement McBrain has calculated that the black elo is 2855 in my pc. It is only a relative measure. Maintain this level, against different users is not easy.

  5. Is there a way in Personal Openings Guide to make a training for a specific line? Whenever I click training it makes a training session for the main line but I can't work out how to do it for any other lines I'm interested in training with

    1. Not at the moment. This is a long overdue issue, I haven't found the time to work on it.

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
