Gambit 1.0.1

Gambit is a Mac OS X application for chess play and analysis. It allows games to be played against the chess engine "Crafty," and it allows completed chess games to be recorded, replayed, annotated, and analyzed.Gambit uses and is 100% compatible with the PGN (Portable Game Notation) format standard. Support for game annotation includes standard punctuation and evaluation glyphs, variations (and sub-variations), and text comments. Not only does Gambit read, display, and save all of the standard PGN tag-value pairs, it retains non-standard pairs when a game with any is modified and re-saved.Gambit's user interface is uncluttered and intuitive. Crafty's level of play can be adjusted, board appearance can be customized, and the style of chess pieces can be selected. Gambit uses two types of windows. A single List window displays PGN files and the games each contains. Selected games can be examined (displayed) in Game windows, of which any number can be open.Crafty is open-source freeware developed by Dr. Robert Hyatt at the University of Alabama at Birmingham. It can use an opening book and endgame tablebases, and it also "learns" as it plays.Gambit is shareware. It is written in Cocoa and requires Mac OS X 10.3 (Panther) or later. For this release the free trial period has been extended to 45 days from the normal 30 days.
