I think it only infringes copyright if you try to pass it off as your own work, however there shouldn't be any problem if you include some disclaimer
The names of the players are given on our newsfeed. Our editor included his own annotations including a brief quote of something Botvinnik said about one of the intermediate positions. There are no annotations from either of the original players. The litigant is trying to make new law. If he is successful we will probably no longer be able to post chess games on our website and will have to close down our email news magazine.
Can someone shed some light on what is allowed and what isn't for chess copyright?
You're not allowed to copy the written annotations of GM or IM's NM's anywhere without written permission and a royalty payment nor can you copy their work in a book and claim it as your own. Copying game scores is usually ok but you still have to be very careful like if you play a game against player John Doe online you can't publish the game if he didn't consent to having his real name associated with it. It's kind of a grey area when an organization says they can copyright the entire game scores of a tournament this has yet to be tested legally. I do know copyrighting game scores goes all the way back to Emmanuel Lasker in the early 1900's he believed players should be compensated for them but as far as I know nothing came of it.
