iPhone chess board which supports communication with chess engines using the xboard protocol.
iPhone Chess seems to be mostly playable, but i would like to add some new features like piece exchange and en passant pawn taking.
I think the general game mechanics should work fairly reliably, although I think castling may cause some crazy stuff to happen at times, keep an eye out :) Id love to get any feedback about this, its my first Obj-C app, let alone for the iPhone.
