How do I get back into Chessmaster 9000 after moving to another application?

Either tab back into Chessmaster 9000 using Apple+Tab or click on the Chessmaster 9000 icon in the Dock. Chessmaster 9000 will suspend all related processes except for the chess engine itself when moved to the background. This reduces the processor load but still allows computer opponents to consider their move while the user performs other tasks.
