It could be anything, and since I don't know your whole implementation it would be hard to guess. If it was my program, I'd be worried that I was viewing some positions as being repeated positions that aren't really, but I don't know if you are vulnerable to that one. It could also be a bug that's there all the time, but only shows up in this case because alpha and beta are different. You will have to be creative about identifying your own dumb mistake, which is hard, because you already failed to identify your own dumb mistake at least once, since you coded it in. It could be a really hard one. But it's important to fix it because this sounds like the type that doesn't crash you, and doesn't make you look markedly dumber in test suites than last week's version did, it just makes you weaker in real games, and that's a very bad sort of bug. bruce
