The 1st USSR Championship was held in Moscow from October 4 - October 22, 1920, and was not the 1st USSR Championship. Instead, it was advertised as the All-Russian Olympiad, though nobody really knew what was going on. In the wake of World War I everything was confusion in the Soviet Union, and it was not even known with certainty which players were alive or dead, let alone could play. So a kind of casting call was sent out, empty slots filled with local Moscow players, and the following field resulted:Alexander Alekhine
Benjamin Blumenfeld
Dawid Daniuszewski
Ivan Golubev
Nikolay Grigoriev
Alexander Ilyin-Zhenevsky
Arvid Kubbel
Grigory Levenfish
August Mund Dmitry Nikolaevich Pavlov Nikolay Pavlov-Pianov
Abram Rabinovich
Ilya Rabinovich
Peter Romanovsky
Nikolay Tselikov
Nikolay Zubarev.
Living conditions were not good at the time in the country, and the tournament was no bed of roses either. Levenfish later wrote: <"I arrived from Petrograd on the day before the first round and was billeted in an unheated room of a military training hostel. For our meals we were temporarily included amongst the military trainees. The hunger and destruction caused by the intervention and the civil war could be felt at every step, and the food was more than modest">.
Alexander Illyn-Zhenevsky, who organized the tournament, recalled that seven of the players signed a petition threatening to go on strike if the food was not improved and a cigarette ration included. Alekhine did not sign the protest, but said he would act in solidarity with the strikers ..."as he did not think it right to play against hungry opponents." (It is not known whether he extended his solidarity to sharing his food.)
The tournament started as a three-way race, with Abram Rabinovich having a half-point lead over Alekhine and Romanovsky after eight rounds. However, he faded badly with only 2 points in the last seven games and ended tied for fifth, while Alekhine finished with 6/7 to win the title a point ahead of Romanovsky.

Very few of the games are available. For some reason, we are missing about half of Alekhine's games but have all the games of Niklolay Pavlov Pianov. Perhaps his Italian cousin Giuoco Pianov quietly saved them.
At any rate, I have been able to prepare this conjectural list of pairings. While it fits all the known facts, it should not be considered definitive without first hand confirmation.
