Chess is a 3D chess game for OS X, developed by Apple Inc. It supports chess variants such as crazyhouse and suicide chess. It originates in OpenStep and Mac OS X 10.2 and is based on open source software. Apple redistributes the source code under its own Apple Sample Code License.[1][2]

Development

The game's front end is a Cocoa application whose drawing code is based on GNOME Chess. It communicates with the Sjeng chess engine which runs in a separate process. In OPENSTEP and OS X up to version 10.2 (Jaguar), Chess used bitmap graphics with a fixed, pseudo-3D perspective and used an early version of GNU Chess as the back-end engine.

Features

Chess can be also played using voice commands which uses OS X's built-in speech recognition capabilities. Games can be logged using the log feature, which can include information such as names, dates, places, types of game and moves made. In OS X Mountain Lion, Chess supports Game Center and in OS X Mavericks there is a voice-over which says "check" after playing the respective move.
