Phony Benoni: I can't find much on Joseph Feller, but he seems to have been born in the mid-1940s and was one of Luxembourg's best players from the 1960s-1980s. Which, perhaps, is still not saying much, but he was obviously Top Gun down at the local club and most of us have painful memories of that guy.
He played in 9 Olympiads for Luxembourg, which is where most of his games came from. Though his record is not distinguished, he was 1st board four times and 2nd board twice. This meant he could expect at least one good GM drubbing each time, especially before the Swiss System began to be used in 1972.

Total +21 =36 -48 37.1%
He managed to quality for at least two Zonals, which is something positive.
Probably his most memorable win in Olimpbase was over future IM Craig William Pritchett:

Pritchett probably should have taken the draw while he had a chance.
I guess I should submit this game, but it seems a shame to spoil Fuller's perfect record.
