| I can't speak to Chess Assistant, but as a longtime Chessbase owner/user, it lets you: * Search any database (proprietary or freely downloaded) for games matching positions (partial position matches too) * Quiz yourself on openings; e.g. the actual memorization of the move orders, which I don't believe ChessRoots is showing * Generate endless tactics problems to drill on * Generate annotations for games; e.g. branching moves, variations, text comments etc. * Graphical markup of positions, to show tactics like pins, skewers, forks, etc. * ChessBase gives you a perpetual license. You can upgrade if you think new versions are worth it (they usually aren't). I happily used ChessBase 9 for several years before upgrading to 14. It's really not a fair comparison. If ChessBase is Photoshop, ChessRoots as it is now is just a simple painting tool. This isn't to say that ChessRoots can't be something worth the price down the road, but for now this is not a great comparison. Chess.com is also something that I've happily paid for for many years. For $99 a year, you get unlimited tactics training, engine analysis (with Stockfish), and a full license to what used to be called Chess Mentor, in addition to opening specific training. |
