Chess for your browser, featuring different algorithms to play against and a two-player mode. This was a small project for myself during winter holiday to get my feet wet with JavaScript and HTML. View it here: https://hreherch.github.io/Chess/.

These files have been tested on Firefox and Chrome browsers, with a large focus on Chrome. The intention for this project was for personal use so extensive testing on a wide variety of browsers was not done.

The html for the project. The chessboard view is set up here.

Handles most of the model of the chessboard. Takes an OO approach.

Depending on the selected mode for the AI, selects and makes a move for black. Depends entirely on chess.js.

The chess board is stored as a 64 element array, with piece objects (or null) taking up each space. This potentially has room for improvement, considering the use of bitboards to store board information.

The board heuristic uses a simple weighted sum: (value of all black pieces) - (value of all white pieces), with traditional values of K=200, Q=9, Pawn=1, and so on. Because the board does not store information about what pieces it has still, the evaluation function must go through every tile and make this sum, leaving room for optimization.
