AlphaBeta (chess) in Haskell

[Mario Lang]

Hello.

Does anyone know of a AlphaBeta/Minimax module
for haskell, and / or a chess module?

I've found several references on the web, but no
code.  There are little examples in whyfp paper
and in some other Haskell related paper,
but both are far from complete.

Also, I've found a reference to a working mate-problem
solver which was used for HAT testing, but
also, no code.

Maybe someone has something already working
which could be used as a basis.

My plan is to provide a generic AlphaBeta module 
which could be used for different kind of two-player
games.
