High Quality Content by WIKIPEDIA articles! Chess is a chess game for Mac OS X, and its progenitor, OPENSTEP, featuring a high-quality graphical display and support for chess variants such as crazyhouse and suicide chess. Also included are different skins featuring metal, grass, marble and wood. It is bundled with the Mac OS X operating system and is also distributed as free and open source software on the Apple website. The Apple Chess front end is a Cocoa application whose drawing code is based on the glChess OpenGL chess client. It communicates with the Sjeng chess engine which runs in a separate process. In OPENSTEP and Mac OS X up to version 10.2 (Jaguar), Apple Chess used bitmap graphics with a fixed, pseudo-3D, perspective, and used an early version of GNU Chess as the back end engine. Chess can be also played using voice commands which uses Mac 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.
