At the AGM on 2nd April in Sheffield, Jon Diamond retired as President after 7 years and Roger Huyshe (pictured) was elected unanimously to replace him.

Jonathan Chin and Toby Manning were re-elected as Secretary and Treasurer respectively.

Brian Brunswick also retired after 10 years as a Council member, as did Donald Campbell; John Collins, Jonathan Green, Matt Marsh and Andrew Russell were elected to Council.

It was reported at the AGM that the membership had increased in the last year to 441, the first time we'd seen an increase for a number of years. The AlphaGo match didn't seem to have a significant impact on membership yet.

Congratulations to the British Go Association team who beat Italy by three games to one in the online Pandanet Go European Teams. With just two matches to play, their new sixth position (just behind Italy on third board score tie-break) is enough to keep them in the B-League for next season.

Bruno Poltronieri wrote about his win by resignation against Alessandro Pace:

Not a great game from me, but I somehow managed to pull off a win by a couple of points (if we ignore the part where he accidentally let me live in his territory while we were fighting the last 1 point ko...). My main mistake of the game was not living under his shimari before it was too late, which left him with a pretty huge territory. I was quite certain I was behind at that point, so I reduced as deeply as I could.

The British Go Congress was held over three days the first weekend in April at the Royal Victoria Hotel in Sheffield. Andrew Kay started the event with a teaching session on Friday afternoon, followed by a well attended presentation by Lucas Baker from Google DeepMind who explained a bit about the recent successes of AlphaGo and showed us its 9 dan diploma (pictured).

In the evening, 26 players took part in the British Lightning tournament which was eventually won by Andrew Kay followed by Alison Bexfield as the runner up.

On Saturday and Sunday the British Open tournament took place with a good attendance of 84 players, including a large contingent from Cheadle Hulme School who brought 15 of their pupils.

Well, THE match is now over, and we're almost back in the right time-zone, so it's time to give an interim view as to the effects on us in the UK.

Obviously our profile has risen just a little! I turned on to the BBC News on Monday towards the end and lo and behold there was an item about Go and the implications for AI, and I wasn't even surprised... If you look at our page of media mentions for the match you'll see what I mean. I haven't counted, but there must be at least 100 in the National Papers, Radio and TV. Did we appear on all channels?

AlphaGo completed the Google DeepMind Challenge Match with a fourth win to Lee Sedol's one.

In a very close fifth game, AlphaGo threatened to get a very large middle that Lee Sedol had to reduce in order to win. After playing a defensive move that also attacked, AlphaGo looked like getting enough, and, despite Lee Sedol's best efforts, AlphaGo was a couple of points ahead with the komi. With just the smallest yose left, Lee Sedol resigned.

At the closing ceremony, thanks were said and plaudits given to both sides. The million dollar prize will go to various charities.

A total of 54 players turned up at the Cambridge University Social Club for the Trigantius Tournament on a good spring day.

AlphaGo created a big central area, which Lee Sedol cleverly found a way to take apart to make the game 4 of the Google DeepMind Challenge Match close. AlphaGo played some strange moves when it thought it was behind, seemingly to test Lee. However these lost the machine some points and, despite being in overtime, Lee played very accurately and eventually at about 08:45 GMT AlphaGo resigned. Human and South Korean pride have thus risen!

Some more detailed commentary and pictures were available on the GoGameGuru website.

Live streaming of the event will continue again for the final match in the 5-game series, on Tuesday at 4am GMT.

AlphaGo played very strongly in a desperate ko fight by Lee Sedol to take AlphaGo's big territory and thus win the third game of the Google DeepMind Challenge Match.

This means AlphaGo won the match with two games left to play.

Charities will benefit from the $1,000,000 prize.
