In the next few days, humanity's ego is likely to take another hit when the world champion of the ancient Chinese game Go is beaten by a computer. Currently Lee Sedol – the Roger Federer of Go – has lost two matches to Google's AlphaGo program in their best-of-five series. If AlphaGo wins just one more of the remaining three matches, humanity will again be vanquished. Back in 1979, the newly crowned world champion of backgammon, Luigi Villa, lost to the BKG 9.8 program seven games to one in a challenge match in Monte Carlo. In 1994, the Chinook program was declared "Man-Machine World Champion" at checkers in a match against the legendary world champion Marion Tinsley after six drawn games.
