This DVD is the largest collection of annotated games on the market. It contains 122,093 games (resp. 75,463 full games and 46,630 fragments for combinations or endings). The DVD includes all the games that were published in Chess Informants 1-150, from 1965 to the end of 2021. All games are annotated by strong or top players, mostly by one of the actors. See picture 2 for more information. Publisher's Note: NO SOFTWARE INSIDE: Quality Base does not contain any dedicated software; it is designed to be used by almost every free or commercial program on the market. SOFTWARE: Although we recommend ChessBase 16 as the preferred software solution for using the Quality Base 2022 in a Windows environment, an older version of this same program will serve equally well. Mac users can browse QualityBase 2022 thanks to the additional PGN database (for Hiarcs, Shredder and any other program). PGN will also be handy when using any PGN viewer on Android or iOS device.
