PyChess

Chess game written using pygtk.
Should be able to do most things xboard does, but in a nicer gtk/svg enviroment.

The goal of pychess, is to provide a fully featured, nice looking, easy to use chess client for the gnome-desktop.

The client should be usable both to those totally new to chess, and those who wants to use a computer to further enchance their play.

It has a nice looking tabbed iterface, containing a chessclock and an animimated chess board with drag 'n' drop.
I has full pgn+epd read/write support and supports all xboard/cecp engines.
It has full buildtin support for chessrules, and even has its own, working out of the box, python chess engine.
It can show you bookmoves, hints and tips of what your opponent might move in his/her/its next turn.
