The International Olympic Committee banned the Russian team from competing in Pyeongchang in February for widespread doping in the latest edition of the Winter Games in 2014.
However, they will be allowed to compete as "Russian Olympic athletes". under the Olympic flag. The gold medalists will not hear the Russian anthem on the podium.
The IOC says that the OAR team will be by invitation only, chosen by a panel of medical and anti-doping officials from various organizations.
To be invited Russian athletes must meet the usual Olympic qualification standards, but they must also be considered "clean for panel satisfaction", which means they can not have been previously banned by doping and must face extensive testing. drugs prior to the Games.
It is not yet clear if Russian athletes plan to challenge these requirements in court. An attempt by the IOC to ban the Russians from previous doping bans at last summer's Olympic Games was nullified in the Court of Arbitration for Sport.
Under the current rules of the IOC, let's see how the "Russian Olympic athletes" could compete in Pyeongchang:
The Russians have won men's gold hockey under the Olympic flag.
In 1992, shortly after the collapse of the Soviet Union, players from former Soviet countries joined, including future Stanley Cup winners Alexei Kovalev and Sergei Zubov. It was not a punishment but a political expediency in a chaotic political situation.
This time, the neutrals of Russia would have a good chance of gold, in the absence of NHL players. Former NHL star Ilya Kovalchuk, now playing in the Kontinental Hockey League of Russia, is eager to play. "We definitely have to leave," he told the Russian media after the decision of the IOC.
One obstacle could be the leadership of KHL, which previously threatened to take its players out if Russia was punished for doping.
Be a bronze contender, but fight to compete against the two best squads, the United States and Canada. Some female players have also been accused of adulteration-related infractions of their 2014 Olympic shows, so eligibility is a problem.
Russia sent a single athlete to appeal to the IOC board on Tuesday, 18 years old – old skating prodigy Evgenia Medvedeva.
It's easy to see why. Unbeaten in two years, Medvedeva is the clear favorite for gold in women's skating and in a sport where races are short, "I do not know if I'll have other Games in my life after Pyeongchang," he told the board.  She is also not connected to any doping offense from 2014, when she was barely 14.
If Medvedeva goes to the Olympic Games in February, she would join possible Russian medalists such as the skaters Evgenia Tarasova and Vladimir Morozov.
Russia has never been an alpine ski power, but it could have an outside shot in a medal under the Olympic flag.
The slalom specialist Alexander Khoroshilov in 2015 became the only Russian skier to win a World Cup event since 1981, when the Russians still competed as part of the Soviet Union.
Three podiums last season show that it could threaten the top three in Pyeongchang under the right conditions. Khoroshilov is based in Switzerland.
SKI THROUGH THE FIELD
Key Russian skiers of the 2014 Olympic Games have already been banned by the IOC for doping, with four of the five Russian medals stripped.
Of the three Russian skiers who swept the podium in the 50km race on the last day in Sochi, the only one left is the bronze medalist Ilya Chernousov, who now faces a possible improvement to the gold subject to the confirmation of the IOC .
Still, a new generation of athletes could challenge for gold in Pyeongchang, led by Sergei Ustyugov, who won five medals at this year's world championship. The IOC prohibits skiers from Sochi from weakening Russia's strength in depth for relay events, which constitute a third of the program.
According to the criteria of the IOC, Russia should be able to deploy almost a complete team in biathlon, the most watched winter sport in the country.
Russia has been stripped of two medals from the Sochi Olympics, with three banned women's relay teams, but the athletes involved had already withdrawn.
7 times world championship medalist Anton Shipulin could be the key medal contender for Russia, although the new season began slowly.
The rules of the IOC could block Alexander Loginov, who returned from a doping ban last season to win a relay bronze of the world championship.  BOBSLEIGH
The IOC's individual doping bans have already devastated hopes of Russian bobsleigh medals and have taken two gold medals won in Sochi from the country.
Russian sleds were already exhausted by withdrawals from Sochi, even before the best Russian pilot at the two and four men events, Alexander Kasyanov, received a lifetime Olympic ban from the IOC earlier this month.
In an unlikely detail that impresses the IOC, a former athlete banned in the Sochi anti-doping investigation, Alexander Zubkov, is now in charge of the Russian Federation of Bobsled and will supervise the preparation of the athletes.
Russia had counted on Sochi gold medalist Alexander Tretyakov and bronze medalist Elena Nikitina to repeat his success in Pyeongchang, but both were banned by the IOC earlier this month.
The best Russian with hopes of competing as neutral is Nikita Tregubov, who won a silver medal in a World Cup race on November 25 and dedicated it to his forbidden teammates.
On the women's side, hopes for medals seem remote.
The IOC rules on previous doping bans could rule out Russian skating star Denis Yuskov for a sanction he received after testing positive for marij Uana in 2008, even though it is not a substance for improve performance.
Tuesday's decision paves the way for six-time Olympic short-track champion Viktor Ahn to return to South Korea and compete for more medals.
Formerly known as Ahn Hyun-soo, he changed his allegiance to Russia after failing to form the South Korean team for the 2010 Winter Olympics, and his return to Pyeongchang will be highly anticipated, regardless of which flag he competes in. .
The female skater Olga Fatkulina is discarded after the IOC took her silver medal in the 500 meters of the Sochi Olympic Games earlier this month and banned her for life at the Games.
Two of the Russian gold medalists of the Sochi Olympics, the slalom the snowboarders and the married Vic Wild and Alyona Zavarzina could return as neutrals, although they still have to comment on the decision of the COI.
Medals are potentially possible in other disciplines, such as the outdoors or snowboarding. cross
There could be chances for medals for the "Russian Olympic athletes" in freestyle skiing, sledding and women's curling.
Whether or not they compete under their own flag, ski jumps and Nordic combos seem unlikely to result in any medal for the Russians.
