Aug-13-06    lopium: He will soon be 100 years old of age! Good luck. Aug-13-06    Knight13: And I soon learned that he died when he was 99 years, 364 days, 23 hours, 59 minutes and 59 seconds old. Aug-13-09    Phony Benoni: Probably his two best known games are Bronstein vs E Rojahn, 1956 and E Rojahn vs M Czerniak, 1939. The loss to Bronstein is a world-famous game of some theoretical importance, while the draw with Czerniak is ... well, look at it yourself. Aug-13-09    Eastfrisian: .. and still living?!. Happy birthday Mr. Rojahn. Aug-13-09    whiteshark: 100 years! Happy Birthday <ERNST ROJAHN>! Aug-13-09    MaxxLange: incredible. A century! Happy Birthday, Mr Rojahn, from American woodpusher! Aug-13-09    Ragh: Must have been a scintillating century! Aug-13-09    WhiteRook48: <Knight13: And I soon learned that he died when he was 99 years, 364 days, 23 hours, 59 minutes, and 59 seconds old.> and 999,999,999,999 picoseconds Sep-16-10    technical draw: Ok what's this 100 years old thing? According to the bio above he died in 1977. Sep-17-10    whiteshark: <historical draw> I smell a biographers conspiracy here. Mar-05-11    Nilsson: This is a little bit mysterious. I remember I saw comment about this game in TFS. ( Tidskrift för Schack ) After the olympiad in Moscow.(1956) If you check position after the logical move 9.Qd4 ECO C58 1. comment nr.1 page 309, they respond to the game Agrinskij - Kuznecov, SSSR 1961, and no comments to this Bronstein-Rojahn game. Euwe recommends 9..Nd6 instead of 9..Nb6 Stockfish (today) agree.( Black is better)I guess that is the explanation why we don´t see this variation anymore. /JN Jul-22-11    Stonehenge: < technical draw: Ok what's this 100 years old thing? According to the bio above he died in 1977. > According to Norwegian sources he died in 1964. Apr-09-12    Tabanus: Here is a picture from the olympiad in Buenos Aires 1939: http://www.ara.org.ar/chs/ajedrez/p.... Rojahn is standing to the right, and I believe Senorita Ruth Bloch Nakkerud is smiling at him? From http://www.nackerud.org/nakkerud_fa... I get the impression that the two later married. Apr-09-12    Tabanus: <According to Norwegian sources he died in 1964.> Are you sure? I cannot find him. ... OK http://sjakkselskapet.no/hist/TJN/T... has 1964.
