Project requisites

• Create a web application to play chess with another player in real time (chess rules in Spanish).
• You must use Phoenix and Phoenix LiveView.
• There must be a graphical UI to perform chess movements.
• UI must be updated in real time.
• UI must display which player won the game, if any.
• Apart from the board, feel free to add user/game feedback and to decide how to display it.
• Any other enhancement will be taken into account for the final score.

Scope

The idea is that two players should be able to play a single game. You can make reasonable simplifications, like:

• Create a game by accessing a random URL like /game/:game_name. Sharing that URL the other player would be able to join the game.
• The user that creates the game uses the white pieces.

Chess Board

• There's a pre-defined chess board with styles you can use as a starting point. It looks like the one in the image below.
• Final HTML is provided, you are responsible of generating the HTML based on your project's data models.
