We are proud to announce our new published Over-the-Board chess database OM OTB increased by 91K and moved its bar over 8 million games. (8,044,244 games). Some players consider this chess database as the strongest ever built partly because it has good size and partly because it collects over-the-board games.

The OM OTB is a leading flagship of the strongest, toughest and most powerful chess database we produce. Yes, the OM GOLEM has 26 million games and OM CORR is used mainly by ICCF players, yet somehow most our players take OM OTB as the reference chess database. We are happy we could add 91 thousands more human games over the last 1-2 months to the overall collection of 8 millions human chess games. That means the world plays constantly quality chess tournaments and we are here to serve them for you.

For our subscribers with OM ULTIMATE package, the files are ready to be downloaded in your folders in folder. Don't forget we have migrated our cloud services to new and closed our sugarsync cloud account. This was caused mainly by lousy services we received from the sugarsync team, we continuously complained about the speed, connection, breaks etc... and nothing changed, they used to have such great service. So we simply said enough and moved to better and faster. The new cloud system via provides very fast and reliable download and syncing and also security of your files. For those who don't have the link yet (who had account with sugarsync) please contact us. We migrated all users, but with all the transfers we could have skipped some. Of course the missed days will be added to your account.
