- MAIN FEATURES INTRODUCED IN THE LATEST RELEASES
• The new Stockfish 19 engine has been integrated, featuring the new Neural Network support (SFNNv16). According to the authors, Stockfish 19 shows consistent performance improvements, with an Elo gain of up to 44 points.
• A Unique online Database with over 11 million games is available. In addition to standard browsing, it is possible to perform targeted searches by data or position. The Unique Database will be updated regularly.
• Added the ability to perform searches in a Database based on PGN Tags (Event, Date, White, Black, ECO, Elo, etc.). This section can be accessed from the main menu.
• Diagram Recognition: this feature allows the user to take and/or upload photos of chess diagrams and convert them into PGN format positions. It is also possible to upload images containing multiple chess diagrams.
• From the Help section, you can download the updated full description of the application. The same description can be viewed at the following address: https://chessstudio.wordpress.com/chess-studio/
• Chess Studio is enhanced with a new feature: the ability to browse an Online Database of games organized by Year and Tournament since 1560. This extensive Online Database will be updated daily with new tournaments and games. Access to this database requires a symbolic Premium subscription.
• A new training feature has been added: the user can load a game from a database and decide whether to move for White or Black without seeing the moves to evaluate his skills. At the end a report will be produced that traces the entire training session. It is possible to use this functionality either by choosing the game to train with or by letting the application decide the game in random mode. To use this functionality, some settings are possible via an appropriate interface. There are various ways to access this functionality, for example from the menu at the top center of the chessboard screen.
• Chess Studio can now read databases in ChessBase format. It can import cbh, cbp, cbt, cbg, cba, cbs and cbc formats, thus it is able to interpret the moves of a game, the variations and comments.
• Possibility of playing online using the Lichess platform. For blind or visually impaired players this feature is fully supported by Voice Over.
• Automatic insertion of engine analysis into games. To enter the analysis, simply touch the engine analysis line. To use this feature you need to activate it in the application settings.
• The new function "Search games by material" has been added, through which it is possible to search for games in a database according to the material present on the chessboard.
• In the Chess Board screen, you can customize the colors of the top bar, bottom bar, buttons and background. The customization is done in the Settings section. In the opening section is the new functionality to explore the Lichess Master Opening Tree. It is now possible to activate the speech synthesizer to announce the moves made both when entering and when viewing a game.
• From the opening section of a database it is possible to save the games relating to a single ECO code or to a single opening variant in a new database. To do this, just swipe left on the opening variant you want to save and follow the directions.
