Chess

Experiment with the [Python Chess] library to see if it's at all useful as an opponent. It should have all the rules and might even be able to generate the game display. Standard MCTS might be playable at a really basic level.

Start by reviewing the linked Python Chess library and the repository's existing board-game framework. Determine whether the library provides the rules and game display, and whether basic MCTS can use it; done means a documented feasibility result or a playable chess opponent integrated into the project.
