FIDE-approved opening names The Wikipedia article on the Latvian Gambit says that the name Latvian Gambit was made official by the FIDE Congress of 1937. I didn't realise that FIDE was in the business of approving names of openings, so my question is:


  What other opening names have been made official by FIDE?
FIDE has long given up on trying to standardize opening names. In 1935 they published a booklet (in French) which attempted to do this, but it had little to no impact. The Latvian Gambit ("Gambit leton" in French) is an ancient opening that was previously known as the Greco Counter Gambit. For some reason the new name for the Latvian Gambit took hold; most of the other proposed new names did not.

Today, as always, opening names are simply a matter of tradition and convention and may vary between countries and writers. For example, in Eastern Europe the Benko Gambit is usually called the Volga Gambit.
