Petrosianic: He was a Senior Master, in the days when that really meant something. He was a master at 15, US Junior Champion in 1955, and had a rating of 2455 when he stopped playing in the mid 60's.He was apparently less well accomplished as a mathematician and logician, judging by his November 1975 article in Chess Life & Review defending Fischer's match conditions, where he literally threw out data left and right whenever it didn't suit the conclusions he wanted to draw.
He played in two US Championships, finishing +0-3=8, and +2-3=6. He got a draw and a loss against Fischer in those championships, and so finished up with a lifetime +1-1=1 score against him.
This game, by the way, was the last game Fischer lost to a fellow American for nearly 4 years. His next loss to an American was the first match game against Reshevsky in Summer 1961.
Kalme was born in Latvia, and, after the fall of the Soviet Union, returned there, where he died a couple of years ago (2003, I think).
