Chess Position vs. Game Database
Shortcomings of classical Chess Game Databases
The first generation of chess databases have been developed to manage chess games – those of the user and of course millions of other chess players. At the time they have were desigend, probably nobody had in mind to manage the players chess repertoire in an efficient way. A repertoire should have reference games, but in general it’s just about positions and moves without any concrete chess games – similar to many chess opening books. The shortcoming of this old approach becomes clear as soon as you start to work with deeply nested variations within a single chess game or one game per main variation. Certainly this is not an intuitive way. The overview is soon lost and the management not efficient.

Advantages of a Position Database
Unlike classical game datbases in a position database like Chess Position Trainer only positions and their moves are stored – absolutely independ of concrete, played games. In this regard position databases are similar to an editable opening book. The presentation of all possible moves for each position is much more concise than in a game database. A separate window you can see all considered moves for the curren tposition and easily edit them. Adding new moves is also simple via the virtual chess board. The navigation through the repertoire is very easy and efficient. You can get to the next branch of moves (variations) by one click or jump from one end position to another one.
Train the Positions of your Chess Repertoire
As Chess Position Trainer doesn’t store games, but manages solely positions and moves, a training via training-center the is very easy. Every position has a training score reflecting how good you know the assigned candidate moves already. The time-proven flash-card concept let you study your repertoire in the most efficient way.
