Wind Chess Databases More Value for Money

The WCH OTB with 9,3 million chess games is the biggest over the board played games collection one could come up with. It all began in 2004 when creators started to collect games and analyze them into single chess database. The origin of name "WCH OTB" dates back to October 2011 when WCH XXL was split between WCH OTB and WCH CORR. The chess database was cleaned of all correspondence and portal games and left only pure human over-the-board chess games. Some chess players consider this database as the strongest available. We update the chess database bi-monthly and usually increase by 100K games. During this time we clean the shop, index the files, correct names, on other words make it better than the version before.
