Dear chess database user,

We introduce a new term for big quality chess databases! 
For our databases that have more than 50 million games we will use term
DaBABase (Data Big Asset Base) with adjective Q50M+ (Quality 50 and more million games).
According to this definition our database WCH ORCA is the first Q50M+ chess DaBABase. Next two Q50M+ chess DaBABases are WCH FALCON and WCH CHEETAH.

Best regards
Your WindChess team
