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/
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.
