Mysterious Tartrate Conquers All At Go

Rubyflame writes "As noted on the Sensei's Library resource for the ancient Chinese boardgame Go, Tartrate, a very strong and mysterious Go player, has recently returned to the Kiseido Go Server (KGS) after a long absence. The game records can be found here. Tartrate first appeared in March, and has yet to be defeated - his identity is unknown." This intriguing story is a little reminiscent of Bobby Fischer's online chess appearances - the Go players on KGS even log their Tartrate number: "tartrate has a tartrate number of 0. If you have played a game with tartrate, your tartrate number is 1. If you have played a game with someone whose number is 1, your number is 2, and so on."

    How feasible is it that its an AI being used to play tartrates games, anyone know?

    I've seen some amazing Go games in my life (while I lived in Tokyo) and I know that the Go mojo is not something you're going to just up and code without being really, really good yourself ... but it is interesting that since we know nothing much about tartrate himself, the first thing that came to my mind is 'someone is running a good Go bot' ...

    Not to detract from his skills, mind. I'm just interested if any of those who have played him could not have been defeated by some of the various Go-playing algorithms which are floating around out there. Some of them are too good.

      Go has a rating system which briefly is explained as follows:

      Begginers start at about 30kuy, as you get better your kuy rating decreases. 1kuy is better than 2kuy. Better that 1kuy is 1dan, dans count upwards to about 7dan. Better than that you start with pro ratings which are not easy to come by.

      AI is far from beating pros at Go
      The best go playing software is rated about 12kuy.

      In otherwords, there are people in my local go club who would beat the best go playing ai :)

      I would be very suprised if it was an AI. Last time I looked (I will admit it has been while), the best AI out there was comparable to an average amateur player. There was even a $1M prize until Y2000 (donor died) for any AI that could beat a Taiwanese professional player. Of course, it could be a very clever way of performing a kind of 'turing test' for someone's next generation AI.

      Anyhow, if it's some AI, then it almost has to be some undergraduate/researcher with some new algorithm, so they probably have quite enough CPU power at hand.

      Not necessarily. Pick of a copy of Blondie24: Playing at the Edge of AI (ISBN: 058-3743638-9346720). It details how a couple of grad student wrote a genetically design neural network to play very good checkers online. Not only did the programmer not know how to play good checkers, but they were very careful to not design hints into the system.

      Now, checkers is a lot simpler than go, but the possibility that it could be done is not impossible. The size of the board the number of possible and number of moves per turn would grow the problem significantly, but the students in the book worked off a single PII 400 throughout their entire project. The design detailed in the book would be very easy to distribute (the neural net evaluate each possible board position at the next turn, multiple machines could evaluate multiple boards in parallel).

  5. Tartrate number == Shuusaku number by cthulhubob · · Score: 4, Interesting

    Before Tartrate got so famous (infamous?) amateur go players were keeping track of how many games they were away from having played Honinbo Shuusaku of the Edo period.

    My Shuusaku number is 5 -- Shusaku (0) - Iwasaki Kenzo (1) - Honinbo Shusai (2) - Iwamoto Kaoru (3) - James Kerwin (4) - Ethan Baldridge (5).

    One of the coolest games on the KGS archives is Tartrate vs. Redrose (Irina Shikshina, a Russian woman who is a 1st dan Korean professional). Tartrate was black and played his first move on tengen (the center of the board), which is an unusual opening. There were two ENORMOUS ko fights, and everybody thought Redrose had won after the first one was over. Check it out, it's a great game.

    If anybody wants a Shuusaku number of 6 and/or a Tartrate number of 3, my username is ethanb on both KGS and DGS (kgs.kiseido.com, and www.dragongoserver.net).

  6. Re:Japanese, not Chinese by cthulhubob · · Score: 4, Informative

    Go was brought to the west via contact with Japan - that's why it's called "Go" here. The game is known as "Igo" in Japan, "Wei qi" in China, and "Paduk" in Korea. The technical terms used in the west are also all Japanese terms (most amateur go players in the US will know what "miai", "hane", "tengen", "joseki", and "aji" mean, for example), even though China and Korea have their own equivalents.

    Evidence shows that go was originally brought to Japan via Buddhist monks from China though. Evidence of go in China predates written records, so it's not certain whether it originated there or was brought from elsewhere.

    This guy is nothing but some 9 Dan pro slumming. No big deal. The REAL big deal would be if it was a program. That would be UBER-REVOLUTIONARY as programs famously suck at Go.

    To cover my ass though - a 9 Dan pro is God Almighty at Go. I will never beat one. I saw a 9 Dan pro play a 6 Dan amateur on a Go server. He spotted the amateur 9 stones and was behind all the way to the end where he pulled ahead and just beat the guy by 3 stones. He knew all along what he was doing. It was slick as hell.

    Here's the kicker though - while he was doing this he was also playing another guy at the same time. That's right - he was playing two games at ther same time and he STILL beat a 6 Dan amateur with a 9 stone handicap. Amazing.

    You should attend a workshop taught by Yang Yilun. He's a 7-dan Chinese pro who teaches in the U.S. Usually the workshops run all weekend for about $200-250. He is an excellent teacher and has written several books, including one coming out soon from Slate and Shell.

    The most impressive thing I've ever seen is at the one workshop I've been to by him. He took all of the students (eighteen), divided us up into pairs (so they can discuss moves with one another), and played us all simultaneously. Then after beating us all (even the pair composed of Keith Arnold, 5 dan and Eagles Song, 4 dan) we cleared off the boards, then he sat down with the first pair, replayed their game from memory, and commented on what they could have done better. Then he replayed the second game from memory... and kept going all the way around the circle.

    He's got another workshop coming up in June, I believe. It's in New Jersey. I'm definitely making the trek.
