   | Notes: |  
   | Di Felice gives three matches between Flamberg and Bogoljubow, all +4-1=1 for Flamberg and all in Warsaw, but one in 1910 and two in 1911. Donaldson and Minev mention a match in 1910 with score +4-0=1 for Flamberg. The Flamberg page at chessgames.com says that Flamberg beat Bogoljubow in two matches in 1910, both +3-0=0. Flamberg's English Wikipedia page has Flamberg - Bogoljubow +4-0=1 in Warsaw 1913. His Polish Wikipedia page has Flamberg - Bogoljubow +3-0=0 in Warsaw 1913, but mentions another report that gives the result as +4-1=0. So far, the only primary source I have (found by Michael Kühl) is Szachista Polski, May 1913, pp.177-178, which gives +3-0=0 for Flamberg in Warsaw 1913. So, all is unclear, but I will tentatively keep the result 4.5-1.5 for Flamberg in 1911, at least until further information comes to light. |  |  |  |
