checkmate or a null), evaluating how close a particular state (board layout) is to that goal, how to generate the different possible following states starting from the current one, and how to traverse what is an immense problem space. An extensive collection of Materials and links you can find here: You may also want to apply test-driven development, which not only ensures that all methods behave the way you expect, but also forces you to write testable, modular code.
