 Eric, the main betatester of the programme, has written a guide, which allows you to go deeper into the use of Lucas Chess. It is written in French, but in this day and age, it is not a big challenge to translate it into your own language. As Eric points out: Lucas Chess is an easy to use program. But it hides some features that are more complex to understand and the following pages try to clarify them. Link to the PDF   Link to Lucas Chess documents

Since version 2.04, you can change the parameters used by the program to determine whether a move is good or bad and also the elo calculated for an analyzed game. The parameters are as follows: limit_score Default value: 2000 Minimum value: 1000 Maximum value: 4000 Data type: integer Determines the score in centipawns from which the position is considered to be totally won, that the probability of winning is 100%. curve_degree Default value: 50 Minimum value: 1 Maximum value: 100 Data type: decimal percentage Expresses the correlation between the score in centipawns and the probability of winning/losing.

New help documents The lack of direct support for the programme has always been one of the programme's Achilles heels, which has been mitigated thanks to the contributions made in several languages and included in the Documents section of the website. Bru888 has produced the most complete guide to the programme. It is a guide divided into 5 parts Play, Train, Compete, Tools, Options, which can be accessed from the documents section of the website. Translations I am aware that it requires a huge effort that is not very visible. I have tried to provide some additional tools, so that from the program itself you can see the changes as you translate (Options/General configuration/Activate translator help mode).  I would like this to be a help to translators, and to encourage more people in those languages that are not sufficiently translated.
