<p>There was a Kaggle competition sponsored by the FIDE looking for an alternative to the current ELO system. The link is:</p>

<p><a href="http://www.kaggle.com/c/ChessRatings2">http://www.kaggle.com/c/ChessRatings2</a></p>

<p>The dataset has over a million actual games covering ~50k players. There's also discussions of the alternative approaches used (the competition itself is now over) and scoreboard of metrics to see how well your ranking system compares.</p>
