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.

 

OM CORR TOP 2015 CTG

This month we are presenting our new addition - OM TOP CORR 2015.CTG. A library, which holds games of top correspondence players with ELO higher than 2300 for last 5 years. You know better the theory these days evolves fast and furious. If you want to be successful at correspondence game, you have to try to reach advantage already at the opening. Otherwise it is proven very difficult to win against a player who also uses strong computer chess programs.

What is better than looking at the openings played by world's best correspondence players. Look if they use your favorite variation or how they are successful with different openings. The library is with format CTG so you can view it with Chess Base program.

Some interesting facts about the tree:

White most frequent move is 1 e4 with success rate 55,5%. Right after that is 1 d4 with success rate 55%. One of the most frequent opening is variation of Najdorf Sicilian with move 6. H4 with success rate 57,3%. When playing black, a good path to keep up, is to play Berlin defense in Spanish game with white being successful only 52,7%. In closed games, the white gets biggest trauma from playing Slav Defense.
