Shodan Go Bet
In 1997, Darren posted a question on the computer go mailinglist:
At the recent FOST Cup I asked the participants two questions. When do you think a computer will be shodan level? and when do you think a computer will be able to beat any human player? Shodan level is 'international shodan', which is maybe 3 dan in Japan, 2 dan in America, 1-dan in Europe.
John Tromp replied with: I wonder if people would still make such optimistic estimates if they had to back it up with, say, a $1000 bet. I (a Dutch 1kyu in 1997) would happily bet that I won't be beaten in a 10 game match before the year 2011.
and Darren accepted under the following conditions: Yes, assuming these conditions:
- It can be anyones program - it does not have to be mine :-).
- It need not be the commercially available version (to prevent you learning weaknesses).
- I can choose the year to play and don't have to wait until 2011.
And so the bet was on.
In December 2010, John Tromp won the match with a score of 4-0, playing against Many Faces of Go. The games were played with a 110 minute sudden death time limit. The match to decide the bet was held at the London Open Tournament in December 2010. John was then an EGF 2 Dan, according to the European Go Database.
