Wind Chess Databases More Value for Money

 WCH ORCA is the ICON of all human chess databases. The database is so huge, the strongest computers are needed. It has more than 84 million human games without duplicates. The origin of ORCA (OM GOLEM) dates back to October 2011. Before this date the common term OM XXL was used. The major components of WCH ORCA is WCH OTB, WCH CORR and WCH PORTAL.

The origin of word ORCA is from the killer whale or orca (Orcinus orca). Orca is the largest and probably most intelligent apex predator in the all world oceans. Our ambition is to develop WCH ORCA database with the similar characteristics in the world of chess.
