In addition to the abovementioned content, new opening lines are published each day during weekdays, and new top-quality opening articles twice a week (“Opening Surveys” column is published on Saturdays, and “Pick of the Week” on Sundays); all these goodies are included in the CHOPIN Professional subscription (monthly or annual) packages. You may find the line and article summaries particularly useful, as they provide condensed information and instant insight into the editor’s choice of most important games and variations. Take a look:
Last, but not least: we firmly believe that it shouldn’t matter whether you come from a nation with rich chess tradition where knowledge and information is readily available; money for expensive coaching sessions mustn’t be a decisive factor; you shouldn’t waste endless hours gathering information just to end up analyzing each move with chess engines – you need a place where everyone should be starting equal. This is why we made the Chess Openings 24/7 online service: a chess opening database for all chess enthusiasts – professionals or amateurs.
