A machine will be the best Go player in the world, sometime before the end of 2020 (even if subsequently eclipsed by human players). The evidence and playing conditions are the same as for the Machine Chess Champion Claim, with time limits etc. adjusted for the playing customs of human high-level Go competition.
Ambiguity clause: I will judge this claim based on its precise wording, unless this wording conflicts with my perception of the intent of the claim. If both intent and wording are ambiguous, I will look for a solution that causes the least damage to FX as a market and game. If you have any questions, or think you may have found a loophole, please contact me!!
