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 ./LucasChessR123_LINUX.sh Launches a GUI with very basic options: Install: Installs in LucasChessR folder inside the home user folder.

Hi, I'm Takashi ( Japanese ). I was looking for a free chess software. Lucas Chess is really good. I posted blog entries in Japanese how to install and use Lucas Chess. http://opening-chess.blogspot.jp/2013/12/lucas-chess.html I installed version 8.0 today and tried to paste PGN, but didn't work. Is that an error?
ReplyDeleteHy takashi.
ReplyDeleteI am one of the contributors of the program.
My advice is:
1)unistall the program
2)download the portable version
3)enjoy lucaschess :)
It works perfectly.
Hi, Michele. Thank you for the advice. I uninstalled the program and downloaded the portable version. I could paste PGN. I'm sorry. I found the reason which I couldn't paste PGN was that the PGN was Chess960's PGN.
DeleteKeep in touch.
ReplyDeleteWithin 4/5 weeks a new version might be released with some novelties.
Hello! I'm Chris (Poland). Thank You for your Lukas Chess 8.0! It is really very, very good program for chess traning. I use Lukas Chess every day!
ReplyDeleteBut some options don't work properly :(
For example:
1. In FICS ELO: The engine (StockfishDD) start to think sometimes (!) when is my turn to move. After this action the appraisement has abnormal value. I was lost many points after that!
2.In FICS Elo: Why it is impossible to change parameters of the engine (also time thinking for more than 5sec for example) and also impossible is, to change the engine for another .(from internal or external engines list)
I'll would like use Houdini engine in 30sec thinking for example
3. In PGN Viewer/READ PGN/UTILITIES: The new function "Create training to Play Like Grandmaster" don't work! After "Accept" the function going to hang.
4.Houdini 4 UCI engine dont work at all! It is impossible to "Save" this external engine.
Kind regards
Chris K.
Hi Chris,
Delete3. Fixed
1. I don´t understand, configuration of ponder is false, this is the only reason to work when it is your turn. I don´t know.
2. It must be a fixed context. The order to engine is look for a move with the time you want, as the engine has 10 minutes if moves < 30 or 5 minutes if moves > 30, engine decides what time to use.
4. Impossible to save?, send me bug.log file, in the lucasChess folder, it says to me what is the matter.
Cheers
Lucas
Hello!
DeleteAbout 1.
In FICS Elo: This situation start sometimes only (one or two times for game) Two times in the same move analyze. Suddenly I can see a green rectangle (engine thinking) and the next move is execute automatically without any my intervention(!)
The appraisement is always abnormal in this situation (-1756 for example. Correct value should be 10 for example and than I lost many point(-1766) and to lose my game with simultaneously elo loss.
About 2:In FICS Elo: Sorry.. but I don't understand, that one's.
Could you like let me know about the time engine problem once again? Past analyze the example game, I can see (clicking to move notation) that engine (Stockfish DD) was think always about
4.5-5 sec only. Why always 5sec only? It is fixed without any change possibility?
And second question....what about multicore set in Stockfish parameters? (default set is 1 core only (Thread=1)) Can I change that parameter and another in FICS Elo mode? I understand that answer is not, isn' it?
About 3: In PGN Viewer/READ PGN/UTILITIES
I expect with hope , that the new function "Create training to Play Like Grandmaster" will be unblock to use in next version of Lukas Chess :)
About 4: Houdini 4 UCI engine dont work:
Save Houdini 4 UCI like external engine is impossible. The "Save" button don't react! I push Save button, but the External Engines window still is on the screen. Lukas Chess don't adopt this engine. Past this action another engines disappear from external engines list! In this situation better will be send bug.log file for you indeed. (About 4 p.m. your time zone. I'm outside home now)
Kind regards
Chris K.
1. I have no idea, this is not a problem that appears when I play, nug.log perhaps says something about it.
Delete2. I have changed the system to use a mix depth +time in correlation with level.
Great! Thank you!
DeleteHi once again!
DeleteThe news!
About 4: Houdini 4 dont work
Houdini 4 UCI work perfect on another computer, ( AMD 1.8Ghz Single Core)
Under my Intel 2 GHz Duo Core - don't work! Why??? :(
About 3: In PGN Viewer/READ PGN/UTILITIES
The great function "Create training to Play Like Grandmaster" work very good on Lukas Chess 7.04 version ! Why under 8.0 dont work :)
:)
I know now what is the problem, your copy of Houdini is in a folder named with polish caracters, can you install it in for instance c:\tmp folder or c:\Houdini or similar with english names.
DeleteIf your folder contains non latin caracters, then bug appears, I´ll try to solve in 8.02.
Thank You! Houdini works!
DeleteBut remains problems nr.1 i nr.3
About 1: In FICS Elo:
Stockfish DD sometimes (1-4 times/game) still going to make the move on my side without my any intervention and points evaluate is not true in this moment. (I was lost or win (unfair) many analyzed games) What the "bug log" file said about it?
About 3:About 3: In PGN Viewer/READ PGN/UTILITIES
I expect with hope , that the function "Create training to Play Like Grandmaster" will be unblock to use in next version of Lukas Chess 8.02 :) This option works good under Lukas Chess 7.05 !
Regards
Chris K.
About 3: perhaps it is a problem with codecs. Downloads for instance http://www.pgnmentor.com/players/Adams.zip uncompress and read with the program, then try to use Create training....If no problem, send me your pgn to test.
DeleteAbout 1: no problem appears in bug.log. The process of the game is, you move and program compares your move with the fics-player move, if different, program remove your move and put the fics-player move. Engine do nothing, it evaluates only both moves.
Cheers
Lucas
About 3: I was try! With adams.pgn, the option "Create trainig to Play Like Grandmaster" works without problems ! I will send you my pgn create under Fritz 13 GUI
DeleteAbout 1 You sad: "The process of the game is, you move and program compares your move with the fics-player move, if different, program remove your move and put the fics-player move"
Ok...I understand,,its correct...but the abnormal engine start is past engine compare , when I'm thinking my next move. The engine starts MY (!) move arbitrary, without my intervention!
THE ENGINE MAKE MY(!) MOVE ON BOARD
Physically move elsewhere the figurines on board without my decision! At that time the points of comparision is usually abnormal. (-1123 for example, or + 1743 or -590 or +399.....variously)
Regards
Chris K.
About 3: Your games are all with Result = *, then it is necessary to select option "Which side" value "Both sides".
DeleteAbout 1: I don´t know. I´ll try to play more with it.
Cheers
Lucas
About 3: Sorry...but after select option which side is win (1-0 or 0-1 for example) problem is the same :(
DeleteMust be another cause...
Cheers
Chris K.
About 3: example you send me do a gm training without problem, with option "Both sides".
DeleteHappy new year
Lucas
Understand.....! Must be "Both Sides"
DeleteWORKS!
Thank you very much, but remains problem nr.1, yet :)
But now...HAPPY NEW YEAR 2014 for you and your Family!
Kind regards
Chris K.
Hello!
ReplyDeleteAnother notice about the "FICS Elo" function. A lot of games on chess servers (on FICS server too) are tainted by engines use!
Wherefore "FICS Elo" training is not real!!
You MUST(!) to change the Fics base games for true FIDE human tournaments games.
At that time the "FICS Elo" training (rename to "FIDE ELO" for example) will be really great!
PLEASE DO IT!!!!!
Kind Regards
Chris K.
Good idea, but the problem is to find games from 1000-1200-1400 elo, perhaps higher doesn´t mind. I don´t know where to find games in a massive way. If you know how to find it say me.
DeleteI have used TWIC database to find games, range is 1500-2800. I will publish it in the short term.
DeleteHi!
DeleteIn my opinion, the problem with engine use... it's not about the 1000 - 1800 ELO; it's about >1800 ELO mostly.
In 2000 - 2300 range I found already one- third of games (3/9)! with engine help ! (practicaly 100% Stockfish moves!)
In 1000 - 1800 range only tenth part of games was with engine help.
So I would suggest, that you change the games >1800 ELO only (or >2000 ELO even)
So this range will be simpler to find.
But important...the games must be from FIDE human tournaments (100% non engine certainty!!)
At that time a Lukas Chess user will be have a real possibility to examine own ELO strength.
Kind regards
Chris K.

DeleteI have yet preparated a competiton using TWIC database and a range of 1500-2800.
DeleteOk...we are waiting :)
DeleteGracias Lucas. Each version is better. Great work. Como programa de entrenamiento es superior a la totalida de programas que he visto. Creeme los he comprado o probado todos. Propuesta. Hay un boton en algun programa comercial que se encarga no de analizar sino de buscar rapidamente blunders...es posible ponerlo? (Si crees que tiene utilidad). Otra ....la base de datos(tools) ...donde se guarda?
ReplyDeleteUna forma rápida de buscar blunders, es analizando con poca profundidad (5 por ejemplo) con stockfish que alcanza muy rápido esa profundidad, pero no sé si hay otra forma, otro factor a tener en cuenta, es determinar qué se considera un blunder, cuantos puntos perdidos respecto al mejor movimiento calculado. Tengo que pensarlo.
DeleteLa base de datos se guarda en la carpeta UsrData con el resto de datos del usuario.
Muchas gracias por la aplicación. He descargado la versión 8.01, no consigo cambiar el tamaño del tablero
ReplyDeletePulsa con el botón derecho del ratón sobre una esquina del tablero, saldrá un menú donde podrás elegir la opción de cambiar el tamaño.
ReplyDeleteCuando se lanza el programa y si la opción de efectos visuales está activa (Opciones-Configuración-Tableros), entonces hasta que no se elige cualquier opción del menú principal, no funciona el botón derecho.
Can you go into more detail about the mouse shortcuts? What are they, specifically?
ReplyDeleteIt refers specifically to move of pieces.
DeleteThere are two modes, one of them needs that you click in both squares, in origin and in destination, in any order and move is done. The other if you click in a destination square and only a piece can move to this destination then move is done, in other case program wait to you press in origin square.
Hello, great program! I have one problem - I use it in ubuntu (linux) through wine and I have problem opening kibitzer window...I add new kibitzer, but when I choose it nothing happens...
ReplyDeleteHi, I am working on it from this morning. When I have a solution I will publish a new release.
DeleteThat was fast! Thank you. If it helps, here is similar problem with more details:
ReplyDeletehttp://forum.winehq.org/viewtopic.php?f=8&t=19509
And if I may add a suggestion - it would be great if you could make analysing position simpler (in a way that you could try different variations on the board with engine(s) running simultaneously and calculating options, like in SCID)...maybe kibitzer does that, but I don't know, as I can not use it.
You could test: download and replace these two files :
ReplyDeletehttps://dl.dropboxusercontent.com/u/18461840/library.zip
https://dl.dropboxusercontent.com/u/18461840/Lucas.exe
And say me please.
Install versions:
DeleteInstallable : https://dl.dropboxusercontent.com/u/18461840/InsLucasChess801a.exe
Portable: https://dl.dropboxusercontent.com/u/18461840/LucasChessPortable801a.exe
I replaced the files and now it works like charm:) Thank you Lucas! It's excellent program now...
ReplyDeleteInstalled this on an old laptop with a fresh installed Windows XP SP3 (inspire 1300 Me051)
ReplyDeleteAfter clicking the exe. nothing happens, it wont even show up in taskmgr.
Any idea how to fix this?
Thanks in advance.
I don´t know.
DeletePerhaps it is a good idea to use the install version :

Thanks for the responds,
DeleteThe problem was netframe work 3.5 had just 4.0 installed.
All working now :)
