Improve `chess` experience for local and multiplayer games

[Marak]

We now have a working chess app using stockfish for local games and multiplayer online to play with buddies where you can challenge your buddies to games.

The chess app is functional with a complete working implementation.

It would be nice to improve the overall UI/UX of chess in order to improve the general experience and user interface.

Great first issue for contributors.
