Our most famous chess databases

If you ask us, which is the most favourite product our customers are buying, the clear answer is OM CORR. All ICCF players love it. The OM OTB is the most powerful over-the-board chess database ever made, and many FIDE GM players use it and OM GOLEM - well it's just the biggest one out there.

 

OM GOLEM

OM GOLEM is the ICON of all human chess databases. The database is so massive that the most robust computers are needed. It has more than 31.4 million human games without duplicates. It is a mixture of correspondence, OTB, and portal games.

OM CORR

The OM CORR wasn't always a separate chess database until about seven years ago when the need from correspondence players stood out. With 2.2 million games, it is the correspondence best chess database suited mostly for ICCF players.

OM OTB

The OM OTB with almost 10.2 million chess games is the biggest over-the-board collection of human chess one could come up with. It all began in 2004 when creators started to collect games and analyse them. A must package for all FIDE players.
