Can you imagine someone so unfathomably lame and without a life that they would spend literally millions of compute hours analyzing test positions with a computer?! [cough] Anyway, the thing that answers most nearly is probably the KKUP contests, but they have gone by the wayside since A.T. left. Even so, it took months to complete a single game. On the other hand, it was great drama and I miss the contests. I'm too lazy to organize a new one, but if someone else wants to do it, I would love to play in one.
