It's amazing and ridiculous how many Russian Grandmasters there were from 1900-today (This list includes Estonia, Latvia, Lithuania, etc.)
Kasparov, Karpov, Tal, Taimanov, Geller, Spassky, Petrosian, Smyslov, Botvinnik, Alekhine, Tomashevsky, Ivanchuk, Grischuk, Kramnik, Keres, Krohnoi, Dubov, Nepo... These are just the ones that I could think up on a moments notice.
It's almost mind boggling.
