Re: When is the new grading list coming out?

Alex, Better still would be not to grade those for whom insufficient results are available for a reliable grade. There is a practical issue though that some/many tournaments won't allow ungraded entrants into their rated limited sections or if they allow them in, they limit the prize money. So ther...

Re: When is the new grading list coming out?

Grading systems should be in part self repairing. So assume a player with a grade of 100 based on performances over 3 seasons. They can now achieve 150 standard results but only play 5 games a season. Their own grade will lag their strength but it only affects 5 people a year so doesn't do much harm...

Re: When is the new grading list coming out?

Doesn't that mean that Sam will lose points, even when he scores 5/5 (as he regularly does!) If he scores that sort of percentage, the new player estimation routine might put him in the top 50. :) It's believed to have done that to two perhaps three of the "long play" top 50. There are at least two...

Re: When is the new grading list coming out?

If all juniors this season are being treated as new starters, that means all their results last season were calculated without the 40 point rule being taken into consideration. Therefore, am I correct in thinking that if, last season, an former 80-graded junior player lost to a 140 graded adult pla...

Re: When is the new grading list coming out?

graded at 190, 210, 230 or 250. It may of course affect the pairings and board orders for non-FIDE events. The days have passed when a high British grade was a title qualifier or criteria for international selection. However it does remain as a qualification route to the 2010 British that an ECF gr...

Re: When is the new grading list coming out?

The mathematical iterative process is not really the place to look for errors as it just solves linear simultaneous equations in a different way. The main issues are with grading players effectively on an insufficient number of games and attempting to backsolve to find grades of ungraded players at...

Re: When is the new grading list coming out?

address one perceived problem I've never been convinced there was much of a problem in the first place - at least not in the top quartile. I think the quoted evidence of under performance was collected by running the recursion routine and comparing it to the live grades. If we now accept that the r...

Re: When is the new grading list coming out?

This is all difficult stuff. The way forward must involve: deciding what we want from gradings and looking at solutions more holistically. More fundamentally the evidence now seems to suggest that the recursion program (or equation solver) is somewhat broken where players score less than 15% or mor...

At the risk of contributing to a thread that is showing signs of going Godwin, wasn't it Len Barden behind the Grand Prix, Len probably named the moves 1 e4 c5 2 f4 as well.

Re: Game search

Your first guess was correct. Where was it played, do we know? Only info is "Austria". It seems to be a game which found its way onto the historic databases as a one-off. I didn't find any other games that might have been part of a match or tournament. www.chesslab.com implies it's from a match bet...

Re: Game search

Whilst the Chessbase online database has: [White "Dueckstein,Andreas"] [Black "Lombard,Andre"] The Olympiad game certainly looks plausible. My data source has Lombardy - but AUT played SUI and not USA in that event. But Swiss players were always playing Austrians - so they could have met more than ...
