Nepo won't be able to play under the Russian flag in his match versus Carlsen, due to the WADA ban on Russia for international sporting competitions. Peter Doggers article here
. Yesterday I was looking on the FIDE calendar
to see what tournaments might be happening in the next couple of years and was quite surprised to see Sochi still listed as the venue for both the 2022 World Chess Olympiad and the World Senior Championship. However, the article by Peter Doggers does reference this, at least in part:
"FIDE's Chief Marketing and Communications Officer David Llada provided the following statement:
FIDE can confirm that, due to the WADA sanctions against Russia, Ian Nepomniachtchi will not be allowed to play under the Russian flag at the World Championship match in Dubai.
This ban forbids Russian athletes and event organizers to display publicly the flag of the Russian Federation, the name “Russia”, (in any language or format), or any national emblem or national symbol of the Russian Federation, including on their clothes, equipment, or other personal items, at any event under the denomination "World Championship".
CAS directly clarified to FIDE that these restrictions do not apply to the qualification stage of any world championship, like the World Cup 2021 and the Women's World Cup 2021 that will take place in Russia later this year.
Likewise, the WADA ban does not apply to the Chess Olympiad 2022, since this event does not have the status of "World Championship." Formally, this status belongs to the World Team Championship."
The part that's missing I guess is that the "Russian athletes" competing in the World Senior Championship, as that presumably has to be classed as a World Championship, won't be able to display the Russian flag either.
