THE nicest and most feature-packed chessprogram for OS X. One feature is the UCI support that makes it possible to install a number of chess engines (which needs to be compiled for the OS X platform though), eg. the very good Hiarcs (commercial) and Glaurung (free) engines. Also the builtin engine should give all but the strongest a difficult game too. A chessplayer yourself ? then be sure to check this one out!
