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 11.13d: finally graphics created directly on the board

Graphics created directly on the board This is a long-demanded option, the list of people who have requested it from me is too large to include here. The working mode is similar to that of Lichess, if it is a square selected a circle is shown, if they are several squares an arrow is shown, by default.  It can be customized from the Director option, each element of the band is associated to a key (None, Alt, Shift, Ctrl) pressed at same time right mouse. Elements associated can be changed  from Director The deletion of elements is done by creating an equal element. The keys Ctrl-F1 to delete the last created element and Ctrl-F2 to delete all of them also work. When Director mode (activated by pressing F1,...F10), Shift+Alt+Right Mouse allows user to choose a piece to add. As a facility, when working in Opening Lines , with the right button you can create graphic elements that are associated with the position directly. This behaviour can be disabled from Options
