Summary
This update comes equipped with a greatly improved AI for singleplayer. There is a bigger range of difficulty to choose and AI player responds much quicker than before. We implemented a new and more diversified Opening Book that takes into account the frequency of real chess games moves in order to make the AI feel more natural to play against.
