Can KGS come back to life?

Posté par northlecale le 4 mai 2017

For years now KGS has been suffering from a dripping death in popularity. New players generally prefer OGS because it is easy to set up and use. KGS lost players with each new update of Java because they couldn’t work out how to connect to the server any longer. The top echelon of players departed to new servers. Even Go Federations started to switch over to using OGS – look at France, Sweden, UK, hey – even Ireland. Now though, it looks like it will finally have an HTML client. I don’t remember when wms started working on one, or when I realised that he would never finish one. New clients are coming. GoUniverse or ShinKGS are 2 decent examples right now. Can it bring the players back – perhaps not, but it will at least even out the share of beginners who choose between KGS/OGS to learn to play on.

Death of Brian Gallagher

Posté par northlecale le 16 février 2017

I learnt tonight of the death of Brian Gallagher. He had actually passed away some time ago, right at the end of 2016. A notice was already on the Irish Chess Union website. It seems trite to say it, but it certainly wasn’t the nicest thing to discover. He was only 17 years older than myself, and one of the strong kyu players I had trouble battling against on my visits to Dublin back in the day. Brian managed rather well the Collegians Go Club website back in the days of Geocities, and was twice our representative at the World Amateur Go Championships. Technically he lacked a certain amount of information, for he was want not to learn joseki, but to delve by himself into the game. He was still sharp though, picking up 3rd place in the Top-8. Although detached from Go in recent years (effectively he quit in 2009), he still kept on with Chess. A nice fellow, who left us too soon.

Death of Tony Goddard

Posté par northlecale le 1 février 2017

I learnt of the death of Tony Goddard through a posting to the BGA’s GoTalk list. The email was from Jon Diamond, an old sparring partner of Tony’s. They contested the British Championship together a number of times. A few days after reading the email I am still sad to learn of his passing. Not knowing him very well, I am in no place to write a decent obituary, but I would note a few things about him. As well as the results listed here on Senseis Library he won the Irish Open in 1994 and a mini-tournament in Belfast in 1992. He was living in Belfast around that time, working at QUB by all accounts, and made a small club there. Paul Donnelly learnt a lot from him. They were two ghosts that I chased after for some time. I was pleased to have been able to meet and talk with Tony at the London Open many years ago.

From his own website, I would recommend reading this, this, this, and this. Reading those will take you a while, but its worth it if you are, or were, interested in Tony.

Resolutions

Posté par northlecale le 2 janvier 2017

As if a birthday wasn’t enough to remind you that you are getting older, the arrival of the new year serves to shout the fact loudly at you through a hangover. Time then to celebrate that there is little to do today, and to pretend to wisely invest my time in recording what I am likely to be doing over the next year. Naturally we leave out unrelated nonsense like developing a taste in contemporary Irish history, or trying to speak French without sounding like a complete cretin. No, here I reveal, almost exclusively, what I intend to do over the next year in regards to that game we love to call Go.

  1. For a bit of fun I started an exposition on a different kind of ;San Ren Sei
  2. Then there is the joy of satire in EuroGoHebdo
  3. Continuing to play Go, and not only through ICC but maybe even a real tournament(?)
  4. Continuing proofreading for the EGF newsfeed and translating for the RFG/AGA-EJournal

I think that’s more than enough to be getting on with, don’t you?

Breaking Tiebreakers

Posté par northlecale le 14 novembre 2016

Tiebreakers are not as unimportant as some people might wish them to be. Unless you’re using something like GoDraw, your pairing will be influenced by the tiebreakers which have been chosen by the tournament director. In other words, it is not just at the close of the event that the tiebreakers come into play. The EGF has a page which describes its current policy on tiebreakers - http://eurogofed.org/egf/toursysrules.htm - these date from 2007. This page is not as clear as it might be, and at times is offering some bad advice, but it is relatively useful all the same.

In a recent competition the following criteria were used

Swiss Score, Direct Comparison, SOS-2 – SOS-1, and SOS.

This is an unusual choice, but we can see where it came from. On the EGF’s page we have

If only one tiebreaker is used, then these tiebreakers are recommended:

  • Number of Board Wins.
  • Direct Comparison.
  • SOS-2.
  • SOS-1.
  • SOS.
  • Rating.
  • Previous Order.
  • Lottery.

What the organiser missed is

Recommended Order of Equal Players or Tiebreakers

  • This general order of priority is recommended:
  • Playing more rounds.
  • Playing playoff rounds, possibly with short thinking times.
  • Having equal players.
  • Using tiebreakers.
  • If only one tiebreaker is used, then the recommended order of priority is given by the list of tiebreakers that may be used.
  • Only one of SOS-2, SOS-1, or SOS may be used.
  • If more than one tiebreaker is used in a relative order of priority, then this is given by the relative order in the list of tiebreakers that may be used.

What he might have been further mislead by

Recommended Usage of Tiebreakers

  • Number of Board Wins: It can be applied only in a team tournament. There it is highly meaningful and should be the first tiebreaker.
  • Direct Comparison: Provided it can be applied at all, it is very meaningful because it might be interpreted as an already performed knockout playoff among the tied players. So, for the final results, generally it should be the first or even the only tiebreaker.
  • SOS-2, SOS-1, SOS: They should be used only in McMahon or Swiss. They express a mixture of opponents’ strength, statistical noise, and pairing luck. Their apparent numerical precision is greater than their true significance. Therefore they must be used with care. Application for the final results is doubtful while application for making pairings is reasonable. SOS-2 filters more noise than SOS-1 than SOS; more noise can be filtered in more rounds more easily.

Direct Comparison is a total devil if we try to use it to break ties between more than 1 player, in which case it is not at all a play-off game but an imagination which has run wild. SOS is much better suited to Swiss and McMahon pairings as it is considering the actual tournament performance, and not just extrapolating from 1 game.

An advice he was not given is that Direct Comparison should not be used in pairings, it should only be used at the end of the event in tiebreaking. It should never be used in making the pairings. It was then all rather unfortunate that this system was chosen. We have to consider why it was chosen.

  1. It was chosen because the TD studied the 2007 page and tried to apply it.
  2. It was chosen because the EGF does not validate or rubber stamp championship tournament systems
  3. It was chosen because nobody was brusque enough, or competent enough, to dispute it

Of Wizards and Men

Posté par northlecale le 1 novembre 2016

About a month ago I rediscovered John Terry’s blog about go and the promotion of go. It contains quite a lot of interesting articles, even if it is slightly infected with a grudge against the American Go Association‘s leadership or officialdom, and indeed the use of the word Go as opposed to go. A week ago he wrote an interesting piece about John Power and his legacy in the promotion of the game.

Go Review is dead. Go World is dead. What is left?

To my mind, only go is left. And that is what I promote.

I wish that more people would understand this. Promotion requires an active interest in the sporting aspects of a game.

John Terry doesn’t strike me as an expert on promotion, his video idea was a bit of a dead duck, but he makes some interesting points in his blog. How many opportunities get squandered because we think communication and promotion means sending an email? How can we adapt to a world were the printed medium is commercially inviable – there are no subscriptions we can make to english language publications about Go now. What is the key starting point to getting people interested? Can we be stand offish and hope to entice people with the resources we have, or do we have to decamp to the schools to catch (indoctrinate) them while they’re young? They are big questions; questions which don’t interest most players since they prefer playing instead.

Recently I volunteered as a sort of proofreader for the EGF‘s news feed. As I understand it, the article authors fight over whether to write Go or go. The material is more relevant and vibrant than any of that which has sat on its site for many a year – yet it still remains stand offish. There is no official advert saying « Contributors wanted from Turkey, Ukraine, UK… » – instead you have something of an authorship clique. Viktor Lin is seemingly intent on publishing sporting material – i.e. articles about the games themselves – which should be great. I wonder though, how many people actually read and appreciate what they have on the website? Is it going to be enough to draw interest and sponsors in the new era of the EGF? Time will tell. For now I feel that the new culture is still missing something in terms of inclusivity.

Lines and Numbers

Posté par northlecale le 3 août 2016

The EGD has a Calculator to find rating(GoR) change after any tournament. At the moment, there are at least 2 variations of the rating system with regards to tournament results submission. This means that you can have a different exit rating depending on the country you play in. To show this, we will look at an improving player with an out of date rank – of course he could also be a total sandbagger. His last rank was 10-kyu so he enters at this rank, but actually he is 2-kyu online (about 1800?). Thus he smashes up his opposition – that is he wins 5 games out of 5.

Scenario 1 is the straight up normal mode of operation.

Round Opponent P.Change O.Change
1 1000 +35.6 -34.4
2 1100 +46.5 -42.1
3 1225 +57.3 -47.1
4 1350 +63.9 -47.6
5 1500 +67.9 -44.8

Thus our player (P) moves his rating from 1000 to 1271.2. Notice that opponent 5 loses less GoR than opponent 4. At first sight this seems illogical, but there is an explanation. This is because opponent 5 is in a higher rating bracket, thus his modifier is lower. The total loss in rating for the opponents is 216.

Scenario 2 is where either the Tournament Director, the EGF Member (e.g. Finland’s or France’s Go Association), or the EGD administrators themselves look at the results, decide that (P) needs his rating changed, and do it. Let us pretend his rating is changed to 1300 by one of these three entities before they enter the results into the database. That is, they alter the tournament data before submission.

Round Opponent P.Change O.Change
1 1000 +7.4 -8.3
2 1100 +11.9 -13.0
3 1225 +20.9 -21.4
4 1350 +32.8 -30.8
5 1500 +44.8 -37.5

Thus our player (P) moves his rating from 1300 (or perhaps 1000) to 1417.8. The total loss in rating for the opponents is 111.

Here I do not say which system is better. I only want to say that after all these years we should have only one system, i.e. one complete end to end method of working, in the European Go Federation. One system which we all accept and agree to use. If we do not, then the ratings between one country and the next might not be the same. That is inherently a bad thing for rating integrity.

A few lines

Posté par northlecale le 4 juillet 2016

The following is a small representation of activity in the Irish Go scene. It uses only the European Go Database as a source for data, and thus it is obviously incomplete. We can add some further points, like 2016 being incomplete, some tournaments being split into 2 parts and myself not having the resolve to handle that, and perhaps some events never ever being submitted. Still, it might help to show a few things about the progress of Go in our country. To start with I should explain that Ireland is meant in the geographical sense, that is to say that we blown up the border between the North and the South for the purposes of this little chart. New players are not just those guys who are new to the game, they are also migrant players who happen to pop over to live in Ireland – which is incidentally a very good and proper thing to do.

Given the lack of any other data source, you can’t make any great pronouncements about what you see here on this chart. I would say it shows that we had a boom in activity that started around 2007 / 2008. Although it hasn’t translated into membership numbers as much as we might like it have done, the blue line of new players shows us that we are still in a reasonably healthy state. Even if not all of us have as much time to play as we would like to, Go is still progressing into the country.

Key Definition
New The number of international players playing their first tournament in Ireland AND the number of irish playing their first tournament in a given year
Act The total number of tournaments any Irish Resident or Irish Citizen played in the given year
All The number of Irish (Resident or Citizen) playing a tournament in the given year

Rational Play

Posté par northlecale le 16 juin 2016

Rather a depressing idea isn’t it? Reading an article such as Rational Play in the AGA EJournal leaves me wondering why they need to see a computer program in this light. Is it really so bad to have waved goodbye to some of the outdated ideas of the Edo period at the expense of home-taping killing the Music industry? (And by the way EMI, up yours something Rotten.) No. These days having longer than 15 minutes to spare for a game of Go is a rare occurrance. One way to continue playing is to choose an opponent who doesn’t mind if you escape. I have found that Leela is just such an opponent. Not being quite up to the standard of AlphaGo, and currently retailing for freem it lends itself to being rather a reasonable opponent for myself. So far, whilst sipping a coffee of a day in work, I have progressed up to the mediocre level of 2-kyu. That’s means I have managed to beat Leela when it gave me 7 stones. Not such a hard thing to do I suppose, but I am in no rush for the stressful levels that await me higher up the scale. After a while I might even get in some decent practice against it.

Newsletter

Posté par northlecale le 5 mars 2016

I thought that it was worth taking the time to thank John Doyle for his newsletter initiative. You can read follow it on his own website CorkGo or on the GoogleGroup. He’s aiming to give everyone a summary of the upcoming events in Ireland for the next month. Hot on the list for March is the Confucius Cup, which my son decided we weren’t going to this year. Maybe he is right, he can enjoy the snow at home.

Rory Wales has also put together an archive for all the newsletters on the IGA website, I can recommend reading them for the nostalgia.
