Nikolai Riumin

Nikolai (Nikolay) Nikolaevich Riumin (Ryumin, Rjumin, Rumin) (Russian: Николай Николаевич Рюмин; 5 September 1908, Moscow – 1942, Omsk)[1] was a Russian chess master, one of the strongest Soviet players of the 1930s.

In 1929, he took 5th in a quarter final group in Odessa (6th URS-ch; Boris Verlinsky won).

In 1934/35, he tied for 3rd-4th with Fedor Bogatyrchuk, in Leningrad (9th URS-ch; Grigory Levenfish and Ilya Rabinovich won).

His best International result was at Leningrad 1934 where he shared 2nd place with Peter Romanovsky, behind Botvinnik, and ahead of Max Euwe.

It has led to significant decline in his ability to play competitively, even though he was still a young man.
