I'm working on a rating/ranking algorithm and I'm finally at a point where I can test some hypothesis but in order to do so I need real data. To be honest almost any board game could be used for this but I thought that chess is the board game with the highest possibility of having such a database.

I was thinking of posting it on other stackexchange pages but in the end I thought going to the root would be most efficient.

What the database should fulfill:

  • At least 50 players
  • At least 1000 matches
  • Downloadable (maybe not required if I can parse it from the website chronological)

Since I only play chess on rare occasions I'm not really too familiar with all the websites out there so I hope someone can help me.

  • What is a chess "match?" All I know is that most of the major ones have more than 2 games and people alternate colors. – PartyLovingHermit Jun 19 '17 at 2:55
