Betafish.Js - Chess Ai.

Betafish.js is a website that offers an artificial intelligence (AI) based chess game. It allows users to set up chess boards with different pieces and then have an AI opponent play against them. The AI opponent can be set to have a certain level of difficulty, or it can be set to think for a certain amount of time before making its move. The website also provides users with the ability to take back their moves, flip the board, and copy or set a FEN (Forsyth-Edwards Notation) position. It was created by Gavin and is free to use.
