I did set up a Google news alert for chess carlsen karjakin, but need to check whether it is accessible without a login. [Later: It isn't.] Two useful items flagged by the alert were:-
- 2016-04-10: Speelman: Karjakin’s decision-making in Moscow (chessbase.com)
- 2016-04-15: Magnus Carlsen and Sergey Karjakin unlikely to meet before world title (theguardian.com; Leonard Barden)
This past month FIDE also issued Bids for the World Chess Championships 2018 as an XLS spreadsheet. The title is somewhat misleading, as it includes only restricted World Championships. One nuance of which I wasn't previously aware is the naming of the FIDE championships for young players:-
- World Cadet 2018 (U8-U10-U12),
- World Youth 2018 (U14-U18),
- World Junior 2018
Nearly all of the bids for these and the other three events are for European venues.
