1:3 – First win in round 4: Lee Sedol (9P Dan) beats back…Did he play the Divine Move against AlphaGo (AI) ?

It had been exiting days this week for every Go lover around the globe… and for some of us it had been sleepless nights becaues of different time zones the live streaming in Seoul (South Korea) of the five round games between AlphaGO (AI) and Korean Lee Sedol, 9 Pro Dan was broadcasted via Youtube at 04:00 am GMT.

The first game which was played on Wednesday, 9th March 2016 beginning at 01:00 pm Korean time in Seoul reached a total number of ~100 million viewers around the globe. Very impressive as mind sports (like Chess or GO) mostly count small media attention.

1:3 – First win in round 4: Lee Sedol (9P Dan) beats back…

After some desperately three games (round 1-3 was played on 9th, 10th and 12th March) Lee Sedol had shown tough fights he played every game into byo-yomi… with resigning against Google Deepmind’s artificial intelligence (AI). Google Research department is being represented by the AlphaGo mashine using a self learning neural network.

This Sunday, 13th March has writteen some remarkably comments in the books of Go history (which last more than 2,500 years since is origin in China.) – One human brain won against the distributed version of AlphaGo being hosted in Google’s Cloud with more than 1,900 CPUs (and 280 GPUs).

During the press conferene after game three on Saturday, 12th March the commentator Michael Redmond (9P Dan, author of “Patterns of the SanRenSei” in 2011) descibed the unexpected strength of AlphaGO winning all three games playing some uniquely moves as 3rd (r)evolution in Go history, since the Honinbo House in Japane developed a new style of Fusekis (opening sequence) and legendary 9P Dan Go Seigen was the path finder of the modern go in 20th century.

Gu Li (born 1982) from China, one of the strongest contrahents of Lee Sedol who have battled each other in the uniquely Jubango 2014 stated about Lee’s victory who had white today: “Lee Sedol played the Divine Move“. He meant move 78 (K11) which cracked AlphaGo’s strength in the center and in consequences let die a row of seven black stones with move 176 via S10. Shortly after AlphaGo resigned with white’s move numer 180 (J4), see screenshots.

The Go world under shock… Artificial intelligence wins first round of 5 against 9 Pro Dan Lee Sedol

First tks to David Ormerod and Younggil An (8p) for the detailled report which was available on GoGameGuru shortly couple of hours after Le Sedol resigned in his first game (of 5) against the AI computer AlphaGo. MySRS Blog got some of the photos from there documenting the event in Seoul (South Korea).

It was a short night in Europe from 8th to 9th March 2016 as the live stream started at 04:00 am GMT on Youtube. Regularly playtime 2 hours per player with bio-yomi 3x 60 seconds and Chinese rules. The Go world got under shock today when Lee Sedol resigned as black after a playtime of 95 minutes. AlphaGo won w+ res. (roughly with 2.5-3.5 points ahead).

You can download the Kifus in SGF format which had been re-streamed on Wbaduk, IGS-Pandanet and KGS server from here.

Most impressive for MySRS Blog was the perfect time management of AlphaGO… till 35 minutes playtime both, Lee and AG (AlphaGo) had shown nearby same speed… in the middle game AG slowed down heavily… swapping into the end game AG still just 5 minutes on the clock in reserves, while Lee had 20 minutes available. It seems AG knows exactly to calculate the investment of time for each move. It seems impossible for a human to be so accurate managaing own efficiency during a four hours game.

The 9th March seems to be a bad day for human mankind !

9 Pro Dan Michael Redmond did an excellent job reviewing the game for beginners and people who never played Go – with a live commentary being assisted by moderator Christopher Garlock, chief editor of the American Go E-Journal (eZine magazine of AGA – American Go Association).

In peak the live stream noticed nearby 100,000 viewers, impressively in the world of Go over last years we have noticed 2-3,000 virtually watching a high class game. When publisihng this post it counted more than 870,000. At least AlphaGo can help the global GO community to attract the fascinating board game to new and upcoming players.

The American Go Association (AGA) serviced it’s own live streaming on Youtube, too… with commentator Myungwan Kim (9P Dan) which might be interesting for more experienced players having some basic Go experiences.

Bookmark the time schedule for live streaming following games:

  • Second match: March 10 (Thu) 4:00am GMT
  • Third match:  March 12 (Sat) 4:00am GMT
  • Fourth match:  March 13 (Sun) 4:00am GMT
  • Fifth match: March 15 (Tue) 4:00am GMT




1st night of all nights in GO history: AlphaGo (AI) battles first round agains 9P Dan Lee Sedol (Korea)

It will become some exiting five days from 9th March 2016 on in the Four Seasons Hotel in Seoul (Korea) which can be seen as a historical moment in GO history. March 2016 will proof if a highly skilled human player can be beaten by a Go computer. Lee Sedol (born 1983) from South Korea who picked up the challenge is seen as the world best Professional Go player these days (rank: 9P Dan).

The eldest board game in the world (more than 2,000 years old with origin in Ancient China) can be played since 2015 by Artificial Intelligence (AI) called AlphaGo. Its a new self-learning mashine based on a neuronal net which was developed by Deepmind Technologies, a British corporation which was founded in 2010 and now is being owned by Google.

The Go world around the globe is heavily exicting since January 2016 after the results had been published in Nature (edition: 28th Jan 2016) about the five days fight of European Go Champion Fan Hui (2P Dan) who lost 0:5 against AlphaGO in October 2015. You can download all 5 games as SGF (zipped / unzipped). The astonishing result is seen as a seriously test for the developers of Deepmind around founder Demis Hassabis.

Lee Sedol announced end of February 2016 during a press conference (see pictures) that he is very confident to win 5:0, at least his personal target is 3:2 which would be a big disapointment for him personally (see translation of the interview in the Lifein 19×19 Forum).

On 9th March 2016 starts the live stream of first day on Youtube
at 04:30 am CET / 13:00 KST (= 8th March 20:00 PT / 23:00 ET)
