  1. Thank you for this wonderful Program! But since I've updated to 9.03a (my previous version was 9.03) I discovered that after an analysis of a game the graphics are not shown anymore. Any idea what could be wrong? (My System: Windows 7 SP1, 64bit)

    1. And what about pressing Utilities, Analysis, Show graphics ?

  2. Thank you for the quick reply! Perhaps my comment should have been more verbose (mea culpa!). I've tried this too. I get the message 'One moment please...' and after that, nothing happens. If I'm the only one experiencing this problem, perhaps I should download the latest version and try again...

    1. Yes, it is better to test last version.

    2. Well, now I can confirm that updating via 'Information' > 'Search for Updates' caused the problem (at least for me - for some reason). Downloading and running the program again showed no strange things so far.
      Perhaps it was only me experiencing this unexpected result, because some other odd things happened on my computer lately (a BSoD for example).

    3. I have done now an updating from 9.02->9.03a and I have not any problem, I guess this is not the example correct to trap the bug.

  3. Hi Lucas!
    Is there a typo in the article heading? I think it is Staunton and not Stauton. Just for your info :)
    I love this software and will make an article soon in my blog

    1. Thanks, changed.
      I will watch your web to read the article.

  4. Hi,
    first of all, thank you Lucas for this amazing chess program! I started to use it from version 8 and this new version is way better: more training, more engines, ecc...

    but I have to report a problem (a bug, probably?): when I start a tournament between engines and I choose also the "roce0.0390" engine, when I start the matches appear an error window, that says:"roce: Path does not exist. EnginesWindows\roce\roce39" and the tournament doesn't start. it's not an important bug, I am sure you can fix it for the next version.
    finally, I want to suggest to you a new feature for the next version: could be really cool the possibility for the human player to join a tournament between engines :)

    1. Roce will work in the next release.
      The possibility of joining to a tournament is something that more people asked me. I add your idea to the list of suggestions.
      Thank you very much.

Version 11.17: update of Honey and Stockfish

This update mainly contains the upgrade of two of the main engines:
Honey formerly McCain, which is the default tutor used by the program, now updated to version XI. The author is Michael Byrne (link)Stockfish, version 11 (link)There are some bugs fixed thanks to LinuxOnTheDesktop and others....

Downloads : 
Update, from Information menu, Search for updatesPortable:  LucasChessPortable1117.exeInstallable:  InsLucasChess1117.exe

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 :
