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.

  1. Thank you. So what parts are done? What do you want us to test. I know I can not analyze games yet. Is that suppose to be functional yet?

    1. It is completely done (I want to include something more this summer).
      There was a problem with the default engine, which I just fixed by changing the binary, and the release in github.

      Si la version 11.18 est également actualiser, on restera sur ses mises à jour!
      Merci Lucas pour ce travail!

    5. I don't have time to work with both versions at the same time.
      Version 11.18 will not be updated again except in some extraordinary case.
      The R version has trainings that are not in 11, for example mate in 1/2 or endings with few pieces or coordinate training, or playing against humanized engines like Maia, or the last stockfish/lc0/komodo ... The present and the future is R.

  2. I'm using windows 10 and I have noticed the following.
    1) I can't install Leela via Command option (only way to install Leela). I get a pop up saying "one moment please" and then everything disappears.
    2) Analysis of games does not work when Stability Control is on.
    3) The Analysis display is overcrowded with things overlapping.
    4) Some engine analysis are wrong (Komodo 11). For example on move 23 it says M-5 for white column and shows draw or 0.00 for black column.
    5) Seems like engine is running in the background after analysis is done until you close the whole game screen.
    6) It would be nice to add the "Play Against" or something to the PGN Read and the Databases. Very helpful when training on your games or other people's games.

    These are some things I have noticed quickly. I will let you know when I find more. Thank you, Lucas for the good work.

    1. Thank you very much Lee, I have published a new prerelease:

      1) I have added another attempt to determine the operating system if it is 64 bit. I have fixed the command option. On the other hand, the internal motors I prefer to remain constant, there are the external motor options to make all the changes that the user wants.
      When playing against an engine, UCI options can be changed, there is a tab for it.
      2) fixed.
      3) I cannot replicate it, I need information but directly in my email.

  3. 1) Leela is included with the distribution, lc0, it is activated if OS is 64 bits.

    Replies
    1. I have x64 windows os. Lc0 does not appear on the list of engines to use to analyze or to change as defualt engines (though I see it in Play Against Engine). Besides there is no options to configure internal engines and Leela needs a lot of tweaking and updating the weights all the time. You may add an option to configure internal engines or fix the Command option please.

    2. And when you go to UCI, you can't change it. It has " value" and cannot be changed.

  9. Hello Lucas, first of all, thank you very much for this fantastic software. Impressive work. Congratulations!

    I have noticed some few probably bugs in the R version. I am running the 28a.

    The directors section is not working when i try to adjust the arrows and such. I Click in "edit" and nothing happens.

    The other thing is the play as Grandmaster option. For the first time, once the software is installed, I click at that option, import for example files from Karpov and the training starts normally. But for subsequent attempts, I click this training option and nothing happens anymore. I am unable to use this feature again.

    One question. Is there a way to save the play as grandmaster training that is ongoing to continue later on?

    Once again, thank you very much!

    2. Hello Lucas, thanks for your response.

      Play like a GM is now working.

      The problem now is that I cant change de board colors. I go to options, colors main board and nothing happens....general option works.

      The ditectors is still buggy...I try to change arrows colors, transparency, circles and then when closing this section the whole program shuts-down.

      Thanks again for your efforts..I will be swiching back to version 11.27 for now. I cant find any problems in that version.

      Hope you can solve the R version issues. Looking forward your next final version.

      I will continue to test your R version as well.

      Hope you manage to find a way to add the adjourn to play as a GM. This is a particular feature that I like a lot, but I do not have too much free time to play all at once.

    5. Lucas, I have found a few other bugs.

      Still at the directors section, whenever I try to change, for example, the arrows transparency, the programs keeps suddenly shutting down after hitting the save button.

      The other one is: after inserting a variation at the games comments sector, I am unable to edit it later. I hit the edit variation button and nothing happens.

  10. Hi Lucas,
    first of all, thx for your great work.
    I have noticed two problems, but i don't know if these points are bugs.
    (1) I played a game against the tutor (beginner Lvl 1 for 10 points).
    I thought the tutor allways shows the best solution, but he doesn't.
    The tutor missed a mate in three. I saved the game as pgn to show it to you.
    (2) I couldn't open the pgn with R0.28a, but it was readable with 11.17b.
    If you want the file, please let me know.

    Good luck for further development.

    1. Thanks Lee, fixed in the next update.

      Delete
    2. Hi, I was thinking maybe you can add a new feature: Ability to save a particular external engine setting. For example Leela has many setting for optimization that depend on hardware and/or network. There is Kayra 2, Kayra 3, Kayra 4, Nuclear, Kuidee etc. So instead of changing the parameters individually every time, one can use the predefined setting with the appropriate name . The same can be applied to Stockfish which is now adopting the neutral network approach( I don't know how that will be different from Lc0?)

      Delete
    3. The truth is that I don't know those settings, if they are in text files, I could try to implement the idea.

      Delete
    4. Hi Lucas, the settings are just normal UCI settings but the nets have quite a lot that can be tuned. I think the idea here is to have one engine installed but with a choice of predefined settings, perhaps from a sub list or drop down list. Each combination of settings could be defined with a name to help identify it.

      Delete
    5. Okay, but it is needed to create that list of names with their UCI options.

      Delete
    6. You don't need any list. Just the ability to save UCI options for a given installed engine.

      Delete
    7. I have probably not quite understood what the proposal is.

      Each engine has specific UCI options, so it would not be easy to generalize the set of options, to apply to different engines.

      To save the UCI options for a specific installed engine it can be done easily with External engines, Import, ....

      Delete
    8. Import will just duplicate an engine and it's uci settings. This is not what we are talking about. For example: You open Stockfish 12 UCI options and change Threads to 2 and MultiPV to 10 ( all other options are unchanged). You save this configuration as, for example, StochfishThreads2. Later in the future you install Stockfish 14 and you want the same UCI for it, you just click somewhere linked to StockfishThreads2 and the UCI options are duplicated for Stockfish 14. Is that possible for Lucas chess to auto fill the UCI values?

      Delete
    9. I take note of your proposal, something like supporting uci options associated with names.

      Delete
    10. Yes. Something like that. Thank you Lucas. I also think Opening Lines is not working.

  13. Hello Lucas, how are you? I am testing out your 0.31 version. Thanks for this new update. A couple of bugs I have found. The director section is still crashing when I try to adjust the arrows to my liking. Specially when trying to adjust the transparency or creating a new one.

    The other thing is: I have some custom sounds that I have been using so far. The modify button at custom sound is no longer working, so I am no longer able to add my custom sounds.

  14. I have a problem with the board size on smaller monitors. On my large monitor, it is fine, and I can change the board size by right-clicking the wrench in the upper left corner.

    However on my 13" laptop screen, the bottom of the board is cut off. And I found that the wrench is on the bottom left corner, which is only visible when I click on maximize full screen. But on the max screen view, the rt-click wrench does not give the Change Board Size option (since it's already on full screen).

    I would have expected an option in the Options or Configuration Settings, but it's not there.

  15. Hello Lucas,

    I have noticed a problem when analyzing an imported game. Sometimes, the engine does not analyze the move the player made at all and just evaluates it as 0.0 without looking at it, especially when the number of moves evaluated by the engine is left at default. I think no matter how dumb my move is, the engine should at least spend some time looking at the move made by the player.
    The behaviour was not reproduceable on the non r version of lucas chess.

    Thank you very much for this otherwise great pice of software and especially looking forward to the hinted linux version.

  32. Hi,
    I'd like to give you three suggestions for your very useful program ...

    1) In utility -> observer -> engine it would be better if the chessboard was much larger, currently the size is fixed

    2) In tools -> engines -> motors tournament, the larger window and chessboard and the possibility of having a human among the participants

    3) When I analyze the positions there are very useful options in the program, but it would be better to add a simpler and more immediate one such as playing the position between two engines, without eliminating the options present

    Congratulations again on your program

    2. The program works with full games, there are no adjourns, there are no half games that can be recovered later.
      The workers do their job regardless of whether Lucas Chess is working or not, they have to be launched from LucasChess, but the relationship ends there, there is a database, where they collect a challenge and then leave the game when it is finished. They can be stopped at any time and launch other workers in the future to continue to the next game.

  34. Hi,
    As a first time user of Lucaschess R, I'm not sure on how to use the 'training with a book' feature under openings. It could be helpful if you could tell me how to use it, since it's a bit confusing, without the name of the openings being displayed( have to keep referring chess books) and not having the personal opening guide.

    Could be helpful if you could add the personal opening guide and also even more good if you could do something that displays the openings at every move, like in chess.com

    ReplyDelete

    1. The name of the opening is always accessible, by pressing Config / View PGN information or alternatively the right button on the pgn table.
      In my opinion, the opening lines have the same or better functionality than the personal opening guide. The opening lines allow you to include all the lines of an opening or whatever you want, and train from memory or against engines. The decision not to convert the personal opening guide has already been made.

    1. The two versions work separately, so you can continue using version 11, in the event that it has been uninstalled it is possible to install it again and it will take the old data (unless it has been deleted manually).
      Right now I am working on a bridge program, which has its complications, so it will take several days to develop and publish it.
      I need to know what people want to recover. Right now I am working on the databases.

      The problem is that I am not able to replicate the problem, using the same configuration, so a hypothesis is that there is some collateral effect derived from your data, and to continue with that hypothesis or discard it it is necessary to contrast it with a blank installation.

  40. Hi Lucas,
    I have a question: have you ever thought about supporting the old winboard engines (via winboard protocol or with the wb2uci utility?)
    If I use Wb2uci the motor is loaded, but then it doesn't move
    Okay, many uci engines can be set to a lower elo level, but isn't it a waste to throw away dozens and dozens of winboard engines, each with its own style of play?
    It can be more inspiring (and more useful, I think) to check progress made than a low-powered Stockfish that responds without thinking.

  45. Hi Lucas,
    first of all thank you very much for all your hard work and this excellent program you have given to the chess community! Once upon a time (to be specific: in version 11.14d) you have implemented the possibility to enter moves in algebraic notation via the keyboard (e.g. by typing "Nf3" to move the knight etc.), but now, in version R 1.05a, this feature no longer works. Would it be possible to re-enable this?
    P.S.: In case you can and want to re-enable this feature, remember that you found a nice solution to distinguish between long and short castling in positions where both are possible by using "o2" and "o3" for long and short castling respectively.

    ReplyDelete
    Replies
    1. Now it is possible to move with the coordinates: e2e4, ... it has been easier to implement. If you are very interested in the san notation, tell me and I will study it, checking for side effects.

      Delete
    2. Hi Lucas, thank you for your reply. Yes, I have noticed that it is possible to enter the moves by coordinates. This is of course also a possibility. However, I always loved the possibility to type a complete game directly from the score sheet into LucasChess. Back in the v11.14d times I also created a fun little profile for a voice recognition software (VoiceAttack), which enables one to make moves in LucasChess by saying, for example, "Knight Foxtrot 3". One can then play on a real board and LucasChess announces its moves back in the same way. This feels more natural to me than "g1f3". But, of course, I leave it to your concern if you think its worth to re-enable this feature or not. In case any one is interested, I am, of course, happy to share my LucasChess profile for the voice-recognition program.

      Delete
    3. I don't have time to study side effects, so experience will tell us if there are.
      For the next update, o2 and o3 included (did not remember).

      Delete
    4. Hi Lucas, thank you very much vor releasing version R1.06 and for enabling the SAN notation! I have tested it, and it works only partly. For example, if I want to make the Knight-move "Nf3" but the Pawn-move "f3" is also possible, then upon typing "Nf3" the pawn moves to f3. Thus, the prefixed "N" seems to be ignored and the move is boiled down to "f3".

    5. I have coded fast and wrong.
      I just left a mini update.
      To correct, just go to Information-Search for updates

    6. Hi Lucas, thank you very much for the really fast update! It works flawlessly now. I was surprised that it is mandatory to type "+" and "#" at the end of moves which result in check or checkmate. Would it be easy to make the indication of check and checkmate in the SAN notation optional?

      For testing I just typed some games into LucasChess using the SAN notation, and I did not notice any negative side effects. I think I used all keys that are involved in the SAN notation. Are there any other test I could do to help checking for negative side effects?

      Delete
    7. Thanks Tobias, and if there is any side effect, it will appear with use.
      I just left a new mini update to fix + and #, also to promote, it is possible to write b8=q or b8q.

  47. Hi, I recently encountered a bug in the "personal opening guide" module. I have made more than a dozen opening guides without problems but upon reopening my most recent one, I noticed that some entire variations were missing. When I went to enter some of the moves again, I noticed that my comments that I put in when I originally made it were showing up for the missing moves, implying that the program just wasn't showing them and they were inaccessible. Perhaps there is something wrong with the expand-all feature, although they wouldn't appear even if I manually expanded the line. Note: this opening guide had 101 variations (according to the personal tactics trainer, which still includes all the moves), which makes it my largest one so far, but now only shows about 60% of that.

    I'm using your very exciting programm for my new beginning into the chess world! Unfortunately at a early stage ("Abfahrt vom Banhof Chotkowo") in your Transsibirische Eisenbahn modul, it stops while playing after the italian opening. It doesn't matter which move I chose, it still stops from working (the computer doesn't make any move, and there is no error message like if i'm doing the early Italian Game wrong)

  52. Hello Lucas,

    One bug I found: In the "Director [F1-F10]" menu (accessed via the wrench icon in the top left) I am unable to modify the boxes (e.g. change their color or transparency). Also, I was testing things in this menu and I think it caused the program to break somehow. I'm not sure what exactly caused this but it happened twice and must have been something in the director menu. Now whenever I press the button to enter the director menu, the menu does not open and the program stops working correctly - the computer will no longer make moves and the program allows me to move any piece anywhere on the board, regardless of whether it is a legal move. The program remains broken until I replace my "UserData/__Config__/recursos.dbl" file, so the problem must be somewhere in this file. I can send you a broken "recursos.dbl" file if you think it will help you find the bug.

    2. Unfortunately this problem still exists in version 1.15, but I think I was able to fix it by removing line 1745 of Manager.py (self.resign_limit = -100). The engine still offers draws though. This might be able to be fixed by checking that self.resign_limit > -9999 before offering a draw at line 1773 of Manager.py (otherwise we know that resign/draw is set to never, so we should not offer a draw). This could all be completely wrong though, I have a particularly hard time understanding the code because my Spanish isn't very good.

  58. Hello.
    My problem is to get along with the function 'Read PGN' in case of an annotated game with move evaluation symbols, comments and variations.
    After 'Edit' I find the move list on the right side of the board. To show the window section 'Rating', 'Comments' and 'Variations' I found only one way: right mouse click on a move. Then this section appears at the right edge. But it is only with about two thirds in the screen area. If I maximize the window, this section 'Rating', 'Comments' and 'Variations' disappears. I am not able to reduce the size of the board or of the move list.
    The move evaluation symbols '!?' and '?!' are not displayed correctly in the move list, only the 2nd character appears: '?' and '!'. But '!!' and '??' are surprisingly OK.
    If there is a comment before a first variation move, it will not be displayed.
    Would it be possible to colour the first variation moves commented with a move evaluation symbol in the same way as game moves?

    ReplyDelete
    Replies
    1. Addition: I finally managed to reduce the value in Options - Configuration - Appearance - PGN table - Width (which apparently applies to the move list) to 300, which solves the screen problem. However, it is strange that I had tried several times to correct this value downwards, but the program did not accept this.

      Delete
    2. Options - Configuration - Boards (in the next update in Appearance) - Enable information panel by default

      You can change the size of the pgn table header by dragging and dropping the separations.

      Symbols and comment: fixed to the next update.
      To colour first variation: I take note to study in the future.

    3. Nice programme modification. Thanks.

      2 additional suggestions:

      After 'Read PGN' and 'Edit' there is almost nothing to edit as long as the 'PGN information' is not shown. It is not self-explanatory to find this window section. Would it not be easier to open this 'PGN information' in any case with the 'Edit'-window?

      The colored moves are difficult to read with lighter colors. Colored backgrounds instead of colored characters would help.

      Delete
    4. Options/Configuration/Appearance/Enable information panel by default.
      On live: CTRL P, Right button on PGN table, Config view/PGN information.
      In relation with colored moves, I have to think about.
