laskereshevsky: there's a mistake in the BIO, the 1971 championship was won by GM Mariotti....and for complete it, TATAI also won the 1985 - 1990 - 1991 - 1994/95 national title....
TATAI STEFANO (TATAI ISTVAN) have both the Italian and the Hungarian citizenship...he spended his life jumping from those two countryes....in fact, even if his big part of life was in ITALY, "TATAI" is an Hungarian surname....
As i know, his family was a well-off one.. they ownered same hotels between ROME and BUDAPEST..(and maybe VENICE too...but im not shore about it..)
he was a very smart and culturated person...well know in the tournaments circuit for his good manners.... always well suited.... a kind of chess-gentleman.
as i listened, now he's living his retirement in the Canarian Islands with the family......
