Future version 10 step 07: some bugs fixed

  • Engines:
    • Stockfish updated to version 7
    • Cheng updated to version 4.39
  • Initial puzzle allows now to continue solving (Remes).
  • Bugs fixed:
    • Engines, error in STS copy
    • Lucas-elo, don´t works


  1. Thanks a lot for the continous work!
    This program is such a wonderful tool and my constant companion (even though i'm using it with wine on linux :) )
    It's great that you changed the Lucas-Elo Mode and that it works in this alpha.

    I want to point out a detail that seems inconsistent to me:
    Scrolling with the mouse-wheel is great, but inconsitently applied throughout the program. In the main window scrolling while over the board is inverse to scrolling when over the Movelist. In the Tutor-Boards the scrolling works, but not when analysing a move (doubleclicking on a move in movelist). The best integration i think would be to have one option that defines the direction that the scrolling does (rewind or forward in game) and to stick to that option throughout the program.

    I am quite new to chess, so i'm mostly playing against the weakest engines like Tarrasch/Roce when i want to practise. Mostly i invent challenges to myself, like "Can i beat Roce Depth 1 in 3 Minutes?" and stuff like that. With the old LucasElo it was difficult for me to win against Gaia1, but i find Bikjump1 easier (even though it has higher Elo :) )

    Thanks very very much for all your work Lucas and feel free to ask for help in graphical terms anytime.

    1. This morning I have changed scrolling with mouse to always follow the same direction. :)
      Each engine has ist own weaks, I know Bikjump it is easy to win in a pawns final.

    2. Nice! i hope that downscrolling goes forward in the game :P Thanks!

    3. Yes, in the same way that in the current pgn table.

    4. Wow!! I can't believe someone else made this comment during the same release. I just emailed you Lucas about this :-) .. thank you for the update!

  2. oh and another thing i want to comment on is that i don't play the FicsElo/FideElo/Everest because of the non-stopping CPU calculation, which makes my CPU too hot.
    I would like to play them though :)

    1. I´ll try to add an option and don´t think while player thinks.

  3. Hey again!
    in LC10 alpha 7 adding Roce as an external engine gives an UCI-error. The same is true for the Homer 2.01 Engine ( )
    Roce works when used via the "internal engine" function, but as said cannot be added as an external one.
    Loading Homer 2.01 works in 9.07b without any problem.
    System here is Linux 64 (Manjaro, which is Arch Linux based) running LucasChess with latest wine 1.9.0
    Ok after testing all the engines here is the list of which don't work as external:
    Amyan, Chispa, Hamsters, Pawny, Polyglot, Roce, Ufim

    The exact error message is:
    "The file X.exe does not correspond to a UCI engine type."

    1. I believe I have fixed it, problem is that don´t admit to run uci command more than one time.

      Polyglot is an utility to create/merge polyglot books.

  4. In Tournaments between Engines, is there a way to make it seconds per move instead of total time for each side in the whole game?

    1. Editing each engine, and setting Maximum seconds to think.

Version 11.15b: minimal fixes, minimal news


When analyzing without redoing, it is possible to recalculate all blunders again. (idea of Mattew A.)Database of games: added possibility of set Opening, ECO, PlyCount as tags of games in a database which it has effect when export to pgn, option in Utilities-Massive change of tags.(idea of Marc)Fide/LiChess/Fics elo, eliminated messages when user and player have done the same move.(idea of Andreas W)Fix: Erroneous elo showed in LiChess-elo menu (Andreas W)Games database, problem open some games. (Mattew A)Import pgn in Opening Lines doesn't work. (Jonathan C) From 11.15 to 11.15a Marc: Fix, saving board to an image in clippboard/file. AltK shows the new keys to be used.Andreas W: Fix, engine label when training Find best move.Andreas W: Fix, find best move, changed size of buttons that shows the moves.Andreas W: Fix, find best move, bad window size when resizing board.Stochastic13: Playing against any engine, with tutor, when move is a draw and there is a lot of moves better.Pau…

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.
It is still in pre-release mode, pending enough feedback to give it sufficient stability.
The installation is done in parallel with the previous version, not interfering with each other. This means that both installations can be maintained at the same time.
A version installable and other portable can be downloaded from :
