Am I an idiot, or does that Crafty book scheme miss some transpositions, because of it's clustering system? Wait, those two statements aren't mutually exclusive... When some of the upper bits of the book hashkey, is from the parent position, doesn't that mean that if I'm in an unknown position, that can make a move that transposes into a book position, it won't, because the upper bits will only match the actual parent position(s) from when the book was created? I'm having an idea of another book implementation that I think is quite smart, but I won't reveal anything yet, primarily because I don't know if it works in practice, secondarily because it might not be a new idea, tertiarily because it might not be a smart idea at all :)
