Re: Chess in Iran

The silliest incident was the first round of the 2008 Olympiads. Israel was paired with Yemen in round 1. As soon as I saw this, I knew that Yemen was going to default. Thus Israel won 4-0 and eventually finished, I think, 3rd on tiebreak. They had received an advantage. Dresden 2008 is of course r...

Re: Senior opportunities in 2018

It's not the same structure, with the ACO version having an upper rating limit and several sections below that. The FIDE World Amateur Championship is restricted to plyers rated under 2000 or unrated. That was the structure I invented in Hastings 1995. The ACO event goes much higher. So, of course ...

Re: Senior opportunities in 2018

fake World Senior Championships, whatever next? FIDE it seems have noticed. http://www.fide.com/component/content/article/1-fide-news/10938-announcement-regarding-fake-qworld-championshipsq.html There appears to be an implied threat to organisers and participants. FIDE is obliged to protect all mem...

Re: 2018 Altibox Norway

I've just noticed the time control. "Time control: 100 min. for 40 moves + 50 min. for 20 moves, + 15 min. for the rest of the game with an increment of 30 seconds per move, starting from move 61. Participant is obliged to record the moves on the score-sheet, starting from the first move." This mak...

Re: World Senior Team Championships, Dresden 2018

In the days when it was a over 60 event and a six hour session, the British Seniors would start at 9:30 in the morning. It later switched to the afternoon, certainly by Sheffield in 2011 but had been in the morning at Great Yarmouth in 2007. I remember a 2013 questionnaire asking about morning vers...

Re: World Senior Team Championships, Dresden 2018

This suggests that not only was fax deemed the way to communicate speedily back then, but the technology was apparently still new/uncommon enough that some technical details still needed to be clarified. :lol: In 1983 that was probably reasonable. My guess is that the Commission which drafted this ...

Re: World Senior Team Championships, Dresden 2018

Mind you, it's a set of regulations that haven't been updated for many years Since 1992, so it says. All parts of the Handbook are supposed to be kept up to date by the Commission responsible for them, but I doubt that anyone would admit to ownership of these. In any case, there is " 7.

Re: Preliminary & Quarter Final Results

The larger the player pool, the easier to field a team of players with grades close to the upper limit. If you want to open the possibility of smaller counties being able to compete in restricted competitions, you need the grading rule to be "average under" or "total grade" for the team. I believe ...

Re: A level maths question

Putting aside the outdated chess references and formula, question (i) shows how in my opinion, education isn't keeping up with how things are done in reality. Who would calculate that figure of r manually, having first worked out all those sums? Surely everyone would just put the data into Excel, p...

Re: A level maths question

The issue I have with that is that due to the way the question is structured, if you can't remember the formula in part 1, how many marks for this question can you get? I expect it's in the formula book. Indeed it is in the formula book. Even if you do get the value of r completely wrong you could ...

Re: A level maths question

r=0.400, which is significant at the 5% level (as >0.3783) So the (made up) data is evidence that maths ability and chess playing ability are related. I think this is a good A level stats question with only 2 of the 8 marks for working out r. Most of the marks were for applying the regression test ...

Vaguely relevant to how things are taught, but why teach the counting of the pieces off the board? Why not those on the board?
I normally encourage them to add up either on the board or off the board, depending on which is fewer.

Re: A level maths question

Then you use your brain to work out if the answer is reasonable or nonsense. Yes, but they don't! so it'd be impressive to be out by a factor of 10 and not notice. :P I have seen A level maths students solving equations with the aid of their programmable calculator and getting as far as something l...

Re: A level maths question

Surely everyone would just put the data into Excel, plot a graph, and choose the option in the settings to tell you what r is? And then when the answer is wrong by a factor of 10 they have no idea, because it's just a number. When I operated in the financial derivatives markets it was always fun to...
