Re: [Haskell-cafe] How to represent a board?

Unless you're dealing with a board with millions of positions or more, sparse matrices don't matter. The array package has support for 2d arrays.

Instead of encoding the board, I would encode the position of the pieces: there is usually much less pieces than squares.
