Re: ECF Online Chess

I really enjoyed the yesterday's online ECF 3+2 blitz tournament. It was good fun. I wish next time there are even more players... Next lichess ECF tournament is rapid I think (10m games).

Re: New grading conversions

Sure, that is why there is the "k" factor in the formulae, and it is precisely why I think grades should be calculated using historical data - because the process can calculate the k-factor as it processes the data...

Re: New grading conversions

Assuming they have historical data, with all results for past N years, I wonder why do they not calculate ELOs from scratch instead of converting existing ECF grades to ELO? This would ensure most accurate ELO ratings. - Sure this is computationally heavy process, but it can be done extremely fast i...

Re: Chess & Bridge Withdraw Ray Keene's Book from Sale

Since you guys know how it should be done, please write something so that we can have better alternatives to the Lakdawala books! :D

Re: Chess & Bridge Withdraw Ray Keene's Book from Sale

Looks like people, who probably never wrote any book, envy Curys as he is obviously a hard-working person. It is always easy to criticise someone else's work... As I mentioned before, I have few books written (or coauthored) by him and I do not find them bad at all. - Quite contrary!

Re: Chess & Bridge Withdraw Ray Keene's Book from Sale

I suppose if you publish a dozen Lakdawala books a month there really is no bottom when it comes to quality. I really do not mind. Cyrus has very nice style of writing, and even though the books are not of highest quality, usually they are (IMHO) worth the money as he typically explains most import...

That would certainly have justified the title of this thread.

Re: Don't Understand Grading Calculation

Well, that would be the case with the current system, and that is precisely why we want to move to ELO or GLICKO-2 (I hope ECF people considered GLICKO when they discussed the new grading system). Also, it is highly unlikely (s)he will beat only children, no matter what division we talk about. - The...
