Game data request for clarification, perhaps enhancement

Hi,

At a quick look at some downloaded current games, it's entirely clear to me how to pick out:

  • team match games
  • tournament games
  • "Let's Play" games given a title

I am also interested in whether games are rated or not. In particular, I would like to exclude unrated endgame tournament games from some analysis as the player will play the same position from each side multiple times.

Picking out win/loss/draw is easy. Timeouts are OK as long as chess.com's PGN output remains consistent.

Non-standard (and non-960) openings can be detected from the FEN, and while an amount of work "book" (for thematic tournaments) and non-book positions can be worked out if necessary via access to a suitable opening book. (That is if thematic matches/tournaments start with a FEN and not with a number of book moves the players didn't actually make.)

 

I think I'm left with team match vs. tournament (which I'll look into some more) (any "Let's Play" game with a title will be rare; I care, but not a lot) and rated vs. unrated which I think I have a problem with.

I've added the "rated" feature request to our queue.  I will be back to you when ready.

Thanks. I've very seldom used that selection criterion in the web interface, but had a user yesterday for whom it would have been appropriate to exclude unrated games.

There is  a group "Endgame Lovers" which plays unrated endgame tournaments, and I have no idea how engine correlation statistics change when someone plays the same position from both sides multiple times. (Quite a few times if they advance in the tournament to later rounds.)

Cheers!
