Hypothesis 2: The cluster and the champion are indeed evenly matched. Expect wins and losses. May imply that the game saturates at high levels of analysis, and that there is no such thing as a 'superhuman' go player because the best humans hit the point of diminishing returns.
That wasn't true for backgammon, chess, or checkers, to name 3 solved games, so why would that be true for Go?
Allegedly Cho Chikun was asked how many stones he would want from God and said "about four".
I'm not sure what the corresponding figure would be for chess. (Nor actually what its "units" would be -- chess doesn't have a handicapping system as straightforward as go does, and I wonder whether Elo-like ratings go awry if one player is playing absolutely perfectly.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
