I need to get up to speed in chess in Riga in the 1930’s for an article with a tight-ish deadline.
In the years 1925-1940, when was Em. Lasker in Riga? I don’t have the new biography.
Was the Latvian chess magazine Šahs published prior to 1940? Is there a research collection that has copies in the US? (I did not see them in the White Collection.)
Any accessible English-language references on Latvian (or even Baltic) chess in the 1930’s?
I don’t expect you to do my research, but would appreciate pointers to good resources!
Another thought. Are you familiar with “Ask a Librarian”? If they have that at loc.gov, they will perhaps have access to a national library in Latvia. It would be well to show that you write seriously about chess. TTFN.
