README

Lopez is a simple xboard/winboard-compatible chess engine in python.  At the moment it has no user interface, though it would not be difficult to add a command-line mode, but you can play against the engine in winboard and pair it off against other engines.  It is a toy project, and will currently play a semi-interesting losing game against the Fairy-Max engine.  It's written in python so I don't expect it to be master-level, is really just a personal sandbox for playing with some AI code.

Current status:
 - Iterative Deepening Mini-Max search with alpha-beta pruning
 - Greedy, simple heuristic  
 - Naive board implementation
 - Naive move generation strategy
 - Only thinks on its own turn
 - Poorly defined board interface; goal is to build a proper interface to allow multiple board implementations.
 - See todo.txt for development notes

To use Lopez with Winboard.exe, edit the winboard.ini settings in the %appdata% folder to include entries for the engine:

/firstChessProgramNames={
...
lopez /fd="C:\Python27" /fcp='"./python.exe" c:\users\clay\src\lopez\Game.py'
...
}

/secondChessProgramNames={
...
lopez /sd="C:\Python27" /scp='"./python.exe" c:\users\clay\src\lopez\Game.py'
...
}
