Our OM PORTAL chess database is so huge we had to split it by ECO codes for better downloading

OM PORTAL ECO A: 4,785,204 games

OM PORTAL ECO B: 6,305,485 games

OM PORTAL ECO C: 3,450,518 games

OM PORTAL ECO D: 2,973,275 games

OM PORTAL ECO E: 1,507,607 games

TOTAL: 19,022,089 chess games played online

For players who enjoy chess statistics, we recommend to combine all three chess databases OM OTB+OM CORR+OM PORTAL into one. This is what is currently under OM GOLEM package.
