AjedrezNet

AjedrezNet is a complete chess game designed to run peer2peer games over the Internet. You can easily play with people from all over the world. The game enables you to play over the Internet or a local network through a connection (TCP/IP), or to compete against another player using the same PC. Its only limit is that there is no one-player vs. artificial intelligence option. With AjedrezNet, you can store games in files with PGN (Portable Game Notation) format, open PGN files, and view each game, play by play, from the file. You can delay games, load past games, and even change window colors to spice things up a bit. AjedrezNet offers a great opportunity to challenge your mental reflexes. And not only is it free, but it is also available in various languages.
