Re: Scottish Chess Championship 2009

Heard rumblings (again) that other countries GM's don't get treated the same as English GM's when it comes to the Britsh. I believe the ECF's position is that if it raises money as "start money for IMs/GMs", then that money goes to players who are ENG on the rating list. If the Scottish, Welsh or I...

and there's Qh5 check as another threat.

I think Black's opening is a bit suspect and needs a bit of Rybka inspiration to make it work.

Re: So who's going to the British Chess Championships?

Does anyone know anything about the Zambian?

Fide rating, ECF 2008 grading, British database, International database, TWICs all draw a blank. Google identifies a player of that name in a 1999 event in Uganda but that's as far as it goes.

Knowing where or how he qualified would be an advantage.

I am carrying games from three years ago in my grade of 90.
It's simple enough - just play at least 30 games in each season - then your past results are forgotten (apart from the 40 point rule)

Re: Rough Guide to new grades

Jack, I thought that FIDE, for example, had changed their Elő system a few years back to upgrade ratings game by game, Not quite. The Fide site certainly now has individual results, not just event scores. However the base point of the calculation is the rating in the published list at the start of...

Re: Rough Guide to new grades

First, its based on the assumption that in the days when graders had to estimate the grades of ungraded players and use them in their calculations, overall they overestimated the true strength of those players. What evidence is there to support this? The absence of negative grades is one piece of e...

Re: Rough Guide to new grades

What used to happen was that the local estimated a grade for new players let's say 80. What used to happen is that there was in effect an unofficial and locally based minimum grade. Depending on the grader, new players were assigned a grade of somewhere between 0 and 100 unless their performances i...

Re: Rough Guide to new grades

Or do you believe, as I do that those pesky lighthouse keepers are more of a theoretical amusement, rather than a real issue? Of course. The point is that the frequency of publication and the minimum number of games to qualify for a grade that "forgets" the previous experience are parameters of the...

Re: Rough Guide to new grades

Except for lighthousekeepers, of course. There's an easy answer to the lighthouse keeper problem. Keeper A - grading 130 plays a 30 game match against keeper B - grading 160. They score 50%. If you publish a grading list after 30 games, they swop grades. If you publish the grading list after 15 gam...

Re: British Championship quiz

The event in 1997 was extremely generously sponsored, so the players would have had no serious complaints if they was forced to play on until there was a winner. Wasn't there some row at the time with Mickey in particular arguing that if he was expected to play in an additional event, then he deser...

Re: British Championship quiz

Jack's sixth question (which I myself cannot answer) "6) In what year did the winner and runner-up not play each other? (I know this has at least one answer; I don't know if the answer is unique.)" 2006 at Swansea is one answer. Rowson won with 8.5, Arakhamia-Grant second with 8 but they didn't meet.

Re: British Championship quiz

Starting from 1983 (3) when did the two favourites play in the second round? (4) when did the players who eventually finished first and second play in the second round? (3) would have been 2000 at Millfield with Julian Hodgson and Jon Speelman. I thought it might have been (4) as well but Chris War...

Re: FIDE Delaying/Maybe Abandoning Introducing New K Factors

According to chessbase at http://www.chessbase.com/newsdetail.asp?newsid=5527, the doubling of the K factor has been abandoned for the time being. 6 rating lists a year and a "400 point" rule remain.
