Chess ratings - move over Elo‏ (Email from Anthony Goldbloom)

Hi Alberto,

I hope this is of interest.

Jeff Sonas, the creator of the Chessmetrics rating system, launched a competition to find a chess rating algorithm that performs better than the official Elo system. Within 24 hours, two teams had already created algorithms that made more accurate predictions than Elo. It's no surprise that Elo has been outdone — after all, the system was invented half a century ago, before we could easily crunch large amounts of historical data.

The competition requires entrants to build their rating systems based on the results of more than 65,000 historical chess games. Entrants then test their algorithms by predicting the results of another 7,809 games.

Regards,
Anthony

On chess ratings

Alberto,

I thought that you and the chess community might find this interesting. My project, Kaggle, hosted a World Cup forecasting competition for statisticians. The variable that appeared most often in participants' statistical models was the Elo rating (and not betting prices of the official FIFA ranking).
