This project is mainly a self educational project to learn the various algorithms around chess computers. Inspiration was mainly given by the great chess programming wiki
https://www.chessprogramming.org/ where you can get a good overview about all used
algorithms.
v.24.04:
Official Version since 23.12.
Estimated Elo strength: ~2800, ~70 Elo stronger than 23.12.
main ELO improvement comes from threats evaluation. This was already existing, but deactivated all the time by accident. Now it is properly activated ;)
several small improvements which gives a few ELOs
a lot of refactoring and cleanup of the code (without any ELO improvements)
