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: https://maiachess.com/

  1. 1. Play against an engine won't start, and the same applies to somes Tactics -> Training Positions. There could be others that are not working but those two are what I have checked so far.

    2. I wish you could have included the ability to get rid of the arrows by left clicking. Imagine I use Lucas R on my laptop but the laptop is placed two meters away. Now imagine the discomfort I have to go through whenever I have reach for the laptop just to get rid of the arrows that I have drawn all over the board.

    1. how did you draw it in the first place?

      Delete
    2. After pressing the Draw button, it is necessary to have played a minimum number of moves, I think more than 25 moves each player, and that the engine scores the position as draw or not favorable to the player.

    3. Lucas likes the program so much that I even did some simple tutorials on how to appear it, on my YouTube channel. I have few subscribers, but I copy the link and paste it on facebook and some whatsapp groups.
      Lucas Chess is fantastic ... a complete and completely free training program. I would like to collaborate ... is there any means of financial support? Like an account like wikipedia or firefox have, for supporters to make small deposits, in cash, to support the project?

    4. Thanks for the offer, but I don't want the programme to have anything to do with money. It is made with free tools and in my spare time.

    1. I have an Intel Core i5 7th gen running Windows 10 Pro. The programme was updated but first installation was Lucas R v 1.00. After experiencing the problems with the latest update I went back to v 1.00 which is working just fine.

      Delete
    2. v 1.00 has some bugs fixed in 1.06.
      I have tested v.106 on Windows 8.1 and Windows 10 Pro, without any problem.

    1. The question is another, why are there 6 false positives? Can you answer me?

      Another test, check the virus total with the download URL(perhaps you have a virus in your PC), I just did it, 0 positive. I download the file and compare byte by byte with the original and they are identical.

  4. ola, o programa Lucas Chess R 1.07 esta apresentando problemas na leitura de PGN. quando começamos, por exemplo um exercício de tática ele não permite fazer o movimento certo, tipo se for a vez das pretas, ele permite apenas mover as brancas. mais uma ver agradeço e parabenizo pelo excelente trabalho que vocês tem desenvolvido. o melhor que já vi.

    1. Please, I need you to be much more precise, to be able to replicate the problem, it talks about two very different things, resolution of tactics and pgn reading and I am missing everything in between.

    2. Certo. eu estou usando PGN que são de táticas, ou seja, eu tenho que descobrir qual o próximo movimento, porem em um PGN onde o próximo movimento é das pretas, o programa não aceita mover as pretas e como próximo lance da para as brancas, embora como resposta depois de resolvido o próprio PGN da como lance a vez das pretas.

    1. GMopenings is always active. Could be this the problem?

    2. Hi,
      1) I don't know what you mean with always active.
      2) I had created some bin books and added them to the list, now I have the books deleted, but their names still show in the list. I can even select them, but then there are obviously no moves.
      3) When adding books to the list, I have to leave the "play against engine" and reopen it to see the book in the list.

      Delete
    3. Fixed, I believe the two bugs. To the next update.

    4. I think one feature is really important for creating training from wrong moves:
      Percentage of centi-pawn. The way it is, it creates too many positions. 0.75 is nothing or at least not important in a position with 600 centi pawns ahead.

      Delete
    5. It seems very logical, but how do you think that percentage should be calculated, depending on the different cases, I can think of 4:
      1. the best movement has a score of 600 and the chosen one has 525,
      2. another case that the best move has 75 and the chosen one has 0,
      3. or the best one is 0 and the chosen one is -75,
      4. or the best -525 and the chosen -600.

      Delete
    6. I guess I understand what you mean, but doesn't it work with the tutor's sensitivity. There I have set it to minimum difference in centipawns to 45 and minimum difference in % to 30.
      So lets say with 75 centipawns and 30% would be like:
      1. 600 30%= 420 minimum loss must be 180 cp 525 is only 175 loss in cp =>0
      2. 75 30%= 25 minimum loss must be 25 cp 0 is 75 loss in cp => 1
      3. Ok, with 0 it doesn't work but usually I would say 30 cp loss is 30% -75 is over -30 => 1
      4. -525 30% = -157.5 minimum loss must be 175.5 cp -600 is only 75 loss in cp => 0

      Another issue is: R 1.21 misses the autosave tab in the configuration and is not autosaving my training games against engine.

      Delete
    7. The system used in the programme is to first check if there is a difference in points and secondly the difference in percentage, the system checks both if both have been indicated.
      The autosave is now saved in Databases, and everything is saved.

      Delete
    8. I apparently get something wrong, so ignore this post, if it is not helpful.
      In the tutor's sensitivity we can chose centi pawn loss and percentage of centi pawn loss, but in the creating tactic from wrong moves, we lack the latter option. Useful would also be the option to create only tactics when the position is evaluated less than for example 400 centi pawn difference (hereby excluding lost positions).

      Delete
    9. There is a lot of work that can be done to refine this option.
      Based on the ideas in your message, it occurs to me that if evaluation stages are defined as lost, slightly lost, equal, slightly won or fully won positions, perhaps a change in the stage from the best move to the move made could be indicative of an error to be considered.

      Delete
    10. People nowadays play a lot of Blitz-Games, with a lot of moves in time trouble and a lot of games to analyze and learn from.
      So any system which would reduce the tactics training to more significant training questions would be helpful. Even replacing the centipawn loss with percentage of centipawn loss would be an improvement, I think. When the evaluation drops from +375cp to +300 = 20% is not significant, but from 100 to 25 = 75% hurts.

  6. Hello, V R 1.08.
    -when i play a game Elo-Rating > Lucas-Elo. and when the engine offers to Resign, if I accept: the game offers only the "Resign" icon, while there should be the "close" option .
    -And a small option that I like in the Lucas-classic: in tactics training, when the problem is solved, there was the possibility of continuing the variant. it is for me a good training to play with the material adventage .

    Always, a great pleasure to use Lucas Chess, thank you to all the team for this "R" version and for continuing this project,

  9. I have created few end games using edit start position and saved them as separate files(about 10 lscb files, another 60 to create). I am trying to have them all together as training module or book so everything can be accessed in one place instead of I open each one as separate game. How do I do this? Can someone guide me bit. Thank you.

    1. Thank you. That is done the trick. Now I have couple more questions to clarify.

      1) PKS files on Regular version Vs lscb version in R. Games I saved before is in PKS version which seems not openable in Version R as it is only looking for *.lscb file when I use open game option. Vice versa I can only able to read *.pks files in Regular versions. Is this expected behavior?
      2) PGN Lables --> Edit PGN labels .. This opens up window where I can change the things but nothing seems getting saved..It always defaults to values before after save. Am I missing something here? ( This behavior seems same in Regular version too).

      Thank you again.

      Delete
    2. 1) Yes. A bridge option between two version is pending.
      2) You need to press enter key when changing a label. I have to think of a way that and losing focus is enough.

      I also noticed one more odd behavior when we create new game by using start position..I send you the details with screenshots on to your email.

      Once we edit the start position on small window, position seems not reflecting in main board until we save the game and re-open...

      Not a problem, just thought about sharing as feedback.

    Replies
    1. Those are arrows that the tutor detects and that correspond to the best move that it considers at each moment, with the move of his side and that of the planned by the opponent.
      When the opponent's arrows are activated, then it shows what the opponent thinks is the best move while they are thinking, and it shows the arrows of the predicted moves, theirs and ours.

  12. Hi Lucas,
    First thank you a lot for your program that I use daily to study my opening. Yet I think I'm encoutering a bug. I have 70 lines in one opening (one .opk file in UserData/OpeningLines). I want to use the sequential and/or the static training to brute force learn my lines. But when I click on Training > Configuration > Create training and then test the training it always rotate between like 4-5 lines out of the 70 instead of covering them all.
    Am I doing something wrong ? :)
    Thx, Clément.

  17. Hola Lucas,

    In the director section, the first option to set up the arrows (using the right click mouse) is no longer changing the colors. As I prefer red, I normally swich the first one to red and then the second option (with Alt key) to blue. The alt keeps showing red arrows and the right mouse click still blue, no matter the changes in the director section.

    By the way, which is the key command to erase all arrows and circles in the board at once?

    Thanks for being so responsive and to keep improving this program. It is really unique with all its features.

    Another question: at play against an engine, under advance tab, for the engines that allow setting strengh, does the set strengh option overrides the rest of the parameters showing below? Finally, What does "move selected by the player means?"

    Hope my questions are not too much confusing.

    Muchas gracias Lucas,
    Best,

    1. What version do you have installed? This is a problem I assumed was solved.
      CTRL-F1 clears the last
      CTRL-F2 clears all

      Engines that have the MultiPV option provide the program with the best movement scores.
      The program chooses one of these movements based on those scores, in a very simple way, if it is the best, the first, if it is similar to the player, one that is close to zero, ...
      As of the options, only the number indicated in MultiPV affects it, the more that number is, the easier it is to choose one that fits the chosen option, and the engine loses some power on the other hand.

      When "move selected by player" is indicated, the user is asked to choose one of those options from which the engine has determined.

  21. Lucas is getting better. Thank you. I have two suggestions

    1) Ability for engine to do a self play. For example you are going through a pgn file and you just want to know whether a position is a win, draw or lose with the best play. Click engine self play and an engine plays out a position while you watch.
    2) The Inline Kibitzer to show graphics with fading arrows into a single variation. User can choose how many arrows to show. This helps visualize what plans an engine has with a position.

      I think these are two good ideas. 1) I think it would be a kibitzer, where two engines (by default the tutor) play against each other, until the end of the game, from a certain position.

      Delete
    3. 1)Yes. That would be a good idea Lucas.
      2) And a graphical representation of a variation using fading arrows. This is pretty much the Inline kibitzer shown in graphical form with fading arrows.

      My top priority is to get a stable version, and there is still a long way to go. Also create a version 11 data import system. Then there is code that a person has prepared to incorporate into the program. Right now I am going through a stage that is not very fun in the program.

      Also in Utilities when playing or cteating a game, there is an option = Consult a book.

    3. Also if you have a big data base of strong GMs games, you can create opening books under under Tools--> Openings --> Polyglot book factory . You can then use opening books in conjunction with engines, in Opening lines as you create your opening repertoires.

  23. Hey there,

    first of all thanx for an awesome piece of free software. I really love the abilities and depth of the program! I noticed two things in the recent version R1.15 of Lucas Chess

    1. When I reinit a game against an opponent after a loss, the program slows down very noticably up to a point where it is not really usable anymore. A restart fixes this, so I think there might be semething going on with recursion or memory leaks.

    2. As far as I understood, the Lucas Elo play mode should become gradually more difficult over time, as more and more difficult engines become available. Now, while most of the engines are drawn in red I can select any of the engines to play against. Also selecting a random opponent will not give me a likely rated engine to play against but just choose any of all the engines. It selected Stockfish for me to play against with one of my first games... which didn't go all too well for me :D

    I am playing with the Certabo Board Driver so that might be a thing with one of these problems.

    Thany again and stay safe,
    Paul

    2. 1) I have not been able to replicate the problem, in theory everything is correct, it would be convenient for you to review it with the following version 1.16.

  24. I have used my Certabo driver and not been able to replicate it either. I even tried really hard to lose to an opponent ;-) If you are able to repeat it regularly can you please provide the exact steps you used? If you don't activate the board and just play on the screen are you able to replicate it then? See if deactivating the board before initiating a new game helps. You can reactivate the driver again once the new game is ready. That will tell us if the driver might be causing a problem during the game startup. If you lost the game then I suppose the last move shown on the board was by the computer. Did you actually make that move on the board or just leave the game for the new one?

    1. Hey Graham, unfortunately I'm not able to reproduce the problem, but that's because I run into another problem since the last update to R1.16. In normal playing mode against any of available internal engines, when I place move No. 2 or 3 the board still indicates my move with the LED's, but the move is somehow not transmitted to Lucas chess and the synhronisation between the board and Lucas Chess stops alltogether. This is not happening in any of the compete modes - here the Board and Lucas Chess still work fine together.

      In ShredderChess I don't run into this problem, I have the newest version 1.3 of your driver installed there as well. If I can do anything to help debug, please let me know. Thanx!

  30. hello in the last R 1.17 my antivirus detected the file " W32/Baidu.gen!A ".
    it is known to be able to record keyboard inputs. Do you have doubts about a file located in the updated engines?

    1. What file are you referring to?
      baidubar.dll is of course not included in the distribution.

      Delete
    2. I don't know if this file can be installed into a random folder of the system, there are inconsistencies between the "maia" folder and the IcO exe. which are two different engines!
      > my antivirus is telling me:
      -the path: ... \ LucasChessR \ bin \ OS \ win32 \ Engines \ maia
      -the delited file: lc0.exe
      really strange because "maia" is not "lc0".
      I do not understand at the time!

      Delete
    3. and my antivirus showed up when I activated a " Play against an engine"

      Delete
    4. I don't know either (in relation to baidubar.dll), the only thing I know is that if it exists (baidubar.dll) it has not been with the software I have published.
      Maia is not an engine, it is a neural network created to run with the Leela engine, lc0. It is separate (actually there are two lc0) because it needed a 32 bit compilation to be accessible by all users and the standard lc0 is 64 bit. So the build is a clean build that I have done on my computer with VS2017 and I have no doubt that it is virus free.
      I understand the reticence, and the difficult task that the antivirus have that leads them to be wrong many times, but this of having to prove innocence every time an antivirus does not do its job correctly is quite tiring.
      What antivirus do you use ?

      Could you test with your antivirus this recompiled version, I have done now with current official lc0 sources?:
      https://drive.google.com/file/d/1MSUVAdqkE5dqfk5jiypYhc99iK5-SugF/view?usp=sharing
      It is lc0.exe.

      Delete
    5. my F-Secure scan of this file is green, say no problem.
      Basically I know that F-Secure is very sensitive. I had no idea of a LucasR contamination, but just wanted to report a conflict.
      I would try this evening to restart Maia, for a match. and see if F-Secure detects anything in its file.

      Delete
    6. Great, I will try to publish today an update with new lc0, and other changes.

  36. I love LucasChess but it has some issues have arisen when I attempted to use it for some somewhat involved and complex Tournament issues..This program doesn't have winboard or xboard support at all so I use mostly UCI engines...now one major problem I noticed right away was that the GUI is not closing the engines properly my laptops started running slow and acting up and when I looked at the task manager most/all the engines that were used in the tournament were still showing up in the task manager.(not closed after playing.)I had to manually close them! Some engines seem to lock up for some reason in Lucaschess and when they do the Program Freezes in the tournament window and there is no way to get back to the main Menu (need a bail out button)...On windows OS I can see all they analysis arrows going every which way (Windows 10) but on my Windows XP laptop I only have one arrow that I can see (move arrow) No thinking moves arrows visible Also when running these tournaments it would be very useful to have a Swiss system and a KO tourney Option (Saves alot of time) Thx AR

    1. The support for time is not yet developed, internally there is a variable that collects information about the milliseconds it takes to make each movement, that is the variable that I will give content to, which is not the same as the one that comes in the PGNs I have seen, which would need a conversion.

    1. When analyzing with external Leela engine, the engine gets stuck on one move forever. Here is the bug.log file says -->
      Version R 1.22a
      INFO X CLOSE525: the engine C:\Program Files (x86)\LucasChessR\myEngines\lc0-v0.27.0_weights_run1_68971_3076\lc0.exe won't close properly.

      Delete
    2. The best thing to do is to check that the external engine is working properly by running it directly, then typing go depth 3 for example, and checking if it shows the bestmove.

      Delete
    3. Leela works fine in R1.19 and below versions but when I update to higher versions (R1.22) then Leela stops functionally properly. I did a quick comparison of the code in analysis.py and I see there is are slight differences in lines 152 and 153. Probably the problem is somewhere else when you debug the code. External Leela engine is good, must be something about the updated code.

      Delete
    4. The only way to solve it is if you can replicate the problem. Version 119 and 122 have the same lc0 executable. I have tested adding lc0 in external engines, with the +Import option, I have set it to MultiPV 10, and then I have used it to analyse a miniatura of the PGN menu, and it does it correctly. If you can do the same, we can advance.

      Delete
    5. I see. For me, I download my Leela engine and weights from the Leela site and I add it using the command in External engines page. I have even tried a fresh external Leela after the update but still the same problem. Try getting Leela and weights from the Leela site and adding it using the command button.

      Delete
    6. I have tried to add external engine also using the New button on the External engines page. The problem still is there. Yeah so download Leela from site and see if you can make it work.

    5. I have not made any substantial changes in relation to the analysis, and even less in relation to the engines. I don't understand why it works if you download version 119 and with the current version it doesn't, it doesn't skip the code control. You can see the engine log if you click on Config, Save engines log, and select the tutor and the analysis log. Then in UserData/EngineLogs, you have the engine movements that you can send me to analyse them.

  44. Hi Lucas, first of all congratulations and thanks for the excellent work. I am discovering the program a little at a time and it must be said that a remarkable job has been done.
    I want to ask you some questions (I hope they have not already been asked).
    1. Lichess and Chess.com use Stockfish for game analysis, and at the end they report a list with the number of inaccuracies, errors, and blunders. Is it possible to obtain this information on Lucas? Using the same engine should I expect the same conclusions in lucas chess? ("Average centipawn loss" in Lichess for example and "Average lost scores" in Lucas chess)
    2. It is possible to export a database in excel or txt table format, or alternatively insert editable fields relating to the single record
    Thanks again for the great job! Andrea

    ReplyDelete
    Replies
    1. 1. These terms need to be defined in missing centipawns and integrated into the summary. It is not difficult. I add the idea to the list.
      If you can find out how deep the stockfish analysis has gone, then the results will be similar, if you do a deeper or shallower analysis, they may be somewhat different, it all depends on the time used in the analysis and the machine you are working on, if it is more or less powerful, it will need less time for the same depth.
      2. You can export only to PGN. You can add columns, editing a game and in PGN labels add the label you want, it will appear in the list.

      Delete
  45. Hi Lucas,

    A prayer: if I analyze a game, can I decide the number of variations to show?
    If I choose only the best variant it is too rigid a way, if I choose all the variants the number is excessive and it is very inconvenient to analyze
    Being able to choose the number of variations would be MUCH more useful for studying games and understanding mistakes

    ReplyDelete
    Replies
    1. You can choose the number of moves analysed by selecting the option "Number of moves analysed by engine(MultiPV)", indicating the one you consider most appropriate.
      When analysing a single move, the number of variations is determined on the basis of this same option in Options/Settings/Tutor.

    1. No logro encontrar los motores de maia para jugar contra ellos.

    2. Y por otra parte, ¿hay alguna forma para que los oponentes se tomen más tiempo antes de mover (no me refiero a pensar en mayor profundidad sino a una simulación de un humano tomándose más tiempo)? Hasta ahora este es el aspecto más incómodo, el hecho de que respondan al instante.

  48. Hi Lucas!

    Thanks for developing this amazing software. I would like to know, however, if you were planning on updating your opening lines feature. I have downloaded a lot of polyglot books and, unfortunately, every time I try to import the openings, it will also import all of the transpositions, which causes there to be much overlap. Do you know if you already implemented a way to fix this problem?

    Also, is there a way to generalize engine evaluations per fen? I know there might be a way to do this with polyglot books, but I'm not certain where to go to do that.

    Again, thank you for this amazing software. I see a bright future for it.

    ReplyDelete
    Replies
    1. I have added "Exclude transpositions" parameter. To the next update.

      "to generalize engine evaluations", in Databases, there is in Utilities a Massive analysis option. Perhaps this helps.

      Delete
    2. Ok, thanks!
      I don't know how the mass analysis works, but it looks like it just reanalyzes every move. The best I can get is to exclude book moves from analysis, but beyond that it just analyzes all the moves over again, even if the same move had been analyzed in the database beforehand. I don't know if that's a problem worth solving.
      Nonetheless, thank you!
      Also, there's a problem with the book imports where, if there's a repetition in the book, the import time will be infinite. Actually, this happened once, where I waited like two hours to import some Sicilian variation and it added over 4000 variations, of which 95% were the same line with varying quantities of a repetition. It's very strange. I don't know if that's a book or a software problem. From my knowledge, the book just shows different moves for different positions -- it's not actually a bunch of lines. If this is true, then it should be fixable from your end. Anyhow, let me know what you think.

      Have a great day!

      Delete
    3. Reanalyses only if explicitly instructed to do so, there is an option to indicate this.

      In relation to imports, Is the problem reproduced by ticking "Exclude transpositions"?

  53. Why can't Lucas chess follow an opening book from start? (from the setup position). On all platforms and software, engines are forced to follow an opening book from the setup position until the end of the opening and then the engines start to think. The same opening is played with the two sides switched.

    1. I assume you are referring to inter-engine tournaments.
      In the tournament settings in the configuration tab, you can choose a book that all engines have to follow.
      In the engine tab, in the engine configuration, you can select the book that the engine must follow.
      If this is not working, it is a programming error to be corrected, but it is not because there is no such possibility.

      Delete
    2. Seems to have solved it partly...what about the reverse match....same opening with the sides switched?

      Delete
    3. The engine uses a book or not, a book to all engines or a book to each engine, will, of course, choose the move in the book for the corresponding position. There is not an opening, there is a book, if the book is generated to select moves of an opening, the moves of this opening will be choosed.

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.

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....
