Either German chess organisations prefer to underestimate players' ages when birth dates are unknown (i.e. refer to someone born in 2004 as 6-year-old throughout 2011, though I guess they know their members' birthdays), or Keymar seems to have the birthday in November or December.
According to a
'Hall of Fame' document of the Berlin Chess Association, published in November (or on October 31) 2011,
Quote:
Stand per 31.10.2011 <...>
o 23.-29.10.2011: 11. Offene Einzelmeisterschaft 2011 (U8) - Anreise am So bis 17:30
• in Sebnitz (Sachsen) - Bedenkzeit: 1 Stunde für 36 Züge + ¼ Stunde für den Rest
• 1. Runde: Mo um 09:00
• 81 Teilnehmer (9 Runden Swiss):
• 1. Vincent Keymer/1534 (9) => erst 6 Jahre alt !!
2. Alexander Niemann/1384 (7½)
3. Till Heckmann/Empo/1178 (7)
I.e. he was 6 years old as of 29.10.2011. (I don't speak German, rely on Google Translate.)
Also, according to
the news page of his chess club,
Quote:
18.10.2014
Vincent Keymer wird Sechster bei der Jugend-WM in Südafrika.
Eine Reise, fast um den halben Globus, zum Schachspielen. Das hatte sich Vincent Keymer, 9 Jahre alt und Mitglied des SK Gau-Algesheim, vorgenommen.
(The entry congratulated him on the 6th place in the Junior World Championship in South Africa and stated that he was yet 9 at the time, i.e. born after 18.10.2004.)
I think Nov 1, 2004, is a conservative estimate of his birth date. You can still go through documents of his chess club and try to find out the exact date (good luck, hehe).
