Since the inception we have focused primarily on providing quality games rather than quantity, although over the years we reached the critical mass of 7.7 millions of games. This is something which no other database can claim - so many human games under one roof.
We are proud to also present that Google is rating us #1 not only with largest chess database but also with "correspondence chess database". At the beginning, Opening Master and OM CORR where in one, after while we separated these two and now the Correspondence database reaches it's critical mass of 1.1 million games and growing.
