Version 8 step 5: kibitzers

This new step has some improves:

  • New kibitzers.
  • More precision when selecting and dragging pieces ( Heikki Junes ).
  • "Determine your calculating power" option shows now real game(Toan Luong).
  • Started the Completed translation into vietnamese (Toan Luong)
  • New set of pieces, Abxtadt by Geronimo.
  • Fixed bugs and some other changes, thanks to Dariusz Popadowski, Uli R&U, Heikki Junes, Dieter Heinrich,...

 Kibitzers in 8 dev version now are :
  1. Candidates <new>: shows highest ranked candidate moves of current position. (Proposed long time ago by istolacio)
  2. Indexes <new>: shows abstract and concrete position indexes. Michele Tumbarello has made a great work improving/extending previous indexes, new guide can be downloaded from
  3. Best move: only best move considered by engine is showed.
  4. Best move in one line <new>: to reduce space used by the kibitzer, is showed in one line without head title. There is a button to show title and allow to change its position/lenght.
  5. Select move: allow to choose the next move, and then begin the analysis.
  6. Threats: answers the question: which would make the opponent if he could move again ?.


  1. I'm using Lucas Chess 7.07. You've got a solid program here. Thanks for it.

  3. I removed my comment because I didn't realize I could access 8.0! Can't believe you implemented "best move in one line"!! You solved the problem of kibitzer = separate window in a very unique way.

    1 problem is that when you lock the kibitzer window, only a very small portion of the moves are visible. Even resizing the window and then locking it again does not fix this. weird, maybe only a x64 bug?

  4. ok... can u tell i'm so excited I am posting without fully trying the software. Well, the bug doesn't exist lol. Exiting Lucaschess and then restarting the kibitzer; full line is visible and AWESOME! Thank you.

    1. Thanks thetasquered, I understand your initial problem, as there is a bug, first time don´t change size, it is necessary to close once (I have to fix it).

      In relation to design, to reduce size used by icons, I have possibility to change the four minicons to one that shows a menu with the four options, or two icons, one for menu, other to close, what do you think about ?

      Also I'm thinking darken the background.

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.

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
