In terms of content, this is one of the best databases ever. The authors have appropriately incorporated all the knowledge gained from their users, which they have managed to implement at a high level. The database continues to evolve and has enormous potential. It deserves greater promotion at championship tournaments, as it is suitable for players of varying skill levels. I would like to give the founders more stars, but according to the review, I can only give 5. In any case, I believe that we will hear more about this database, and I highly recommend that every chess player sign up here!
