/* OK first of all, when I wrote this, I just copied my c code and translated to java. I had never written any java code ever before, and now, three years later, I find this code horrible. But because of the many requests for the code I've decided to put out the code anyway, but I warn you, don't code like this! Note that this engine doesn't think ahead, it just evaluate the current position. The best way to proceed is maybe to modify the Analyze function and use it with the MiniMax algorithm. I actually started coding some think-ahead but I think i'ts commented below. Well that's it, and good luck!
