Unfortunately, I've found that not to be the case, for my needs. In chess training, I would ideally want software to be able to:
- Provide a database of quality games that I can use to review my own games against, including the most recent games. The Gigaking database that comes with Chess King is current through October 2011, but cannot be updated. This contradicts what has been publicly advertised as a feature; see the tutorials link above for the part about users being able to "combine" (i.e. merge and update) the database. This feature does not in fact exist in the current version, meaning there is no way to manually update the database (there is no auto-download feature). There also is no position search feature for the database, although the tree display in the interface essentially fulfills the same function.
- Manage multiple games databases. The software can import PGN and Chess Assistant (CA) format databases, but the user cannot manage them easily. It is impossible to delete a game from a database and saving new games into a defined database works only infrequently.
- Analyze games with a strong engine. Houdini 2.0c is included in the package in a dedicated version (i.e. it's not the UCI version that you can then use with other programs as well). While the engine works well in the software interface, for game analysis my method is to look at the game until out of database, then start with the engine, which is standard practice. If the database can't be made current, then it's not nearly as useful. I would therefore have to do that portion of the game analysis with another program.
- Play training games. I wasn't looking for Chess King to do this, since I prefer using the Chessmaster: Grandmaster Edition board and opponents. Chess King has an interesting odds-based training game system which would probably be most useful for beginners or players who are not focused on playing tournaments.
- Publish games to this blog. I was disappointed with the Aquarium 2011 publishing feature, which for some unknown reason blanks out all previous posts on the main blog page. If it weren't for that, I'd use it instead of ChessFlash. As can be seen here, Chess King's game publishing feature doesn't have a scroll box, so can't in practical terms be used for annotated games, because the board scrolls out of sight when going through the game.
