The year 1937 was Fine's most successful. He won at Leningrad 1937 with 4/5, ahead of Grigory Levenfish, who shared first in that year's Soviet Championship. Fine won at Moscow 1937 with 5/7. Those two victories make Fine one of a very select group of foreigners to have won on Russian soil. Fine shared 1st–2nd at Margate 1937 with Keres on 7½/9, 1½ points ahead of Alekhine. Fine shared 1st–3rd at Ostend 1937 with Keres and Henry Grob on 6/9. At Stockholm 1937, Fine won with 8/9, 1½ points ahead of Gideon Ståhlberg. Fine then defeated Stahlberg by 5–3 in a match held at Gothenburg 1937. Fine placed 2nd at the elite Semmering/Baden 1937 tournament with 8/14, behind Keres. At Kemeri, Latvia 1937, Fine had a rare relatively weak result, with just 9/17 for 8th place, as the title was shared by Reshevsky, Flohr, and Vladimirs Petrovs. Fine shared 4th–5th at Hastings 1937–38 with 6/9 as Reshevsky won.
