14.4. Chess

Mac OS X comes with only one game, but it's a beauty (Figure 14-4). Chess is a traditional chess game played on a gorgeously rendered board with a set of realistic 3-D pieces. The program is actually a 15-year-old Unix-based chess program, GNU Chess, that Apple packaged up in a new wrapper.

Talking to Chess

If your friends and co-workers are, for some reason, still unimpressed by Mac OS X and your mastery of it, invite them over to watch you play a game of chess with your Mac—by talking to it.

Open the Chess program. Unless you've turned it off (in Chess → Preferences), the game's speech-recognition feature is already turned on. When it's on, the round Feedback window should be visible onscreen.

To learn how to speak commands in a way that Chess will understand, click the small gray triangle at the bottom of the Speech Feedback panel to open the Speech Commands window. As usual, it lists all the commands that Chess can comprehend.

You specify the location of pieces using the grid of numbers and letters that appears along the edges of the chessboard. The White King, for example, starts on square e1 because he's in the first row (1) and the fifth column (e). To move the King forward by one square, you'd say: "King e1 to e2."

As the Speech Commands window should make clear, a few other commands are at your disposal. "Take back move" is one of the most useful. When you're ready to close in for the kill, the syntax is, "Pawn e5 takes f6."

And smile when you say that.
