2. It is more sensible to limit the variations relative to the ECO classification. This
results in long variations for theoretical main lines (ECO classification position found
late in the game) and short variations for side lines (i.e., early deviations).
Obviously, if you choose a shorter length – absolute or ECO-relative – the tree will be
compact. But then you are liable to lose some valuable information. If you choose a
very large value then the tree will be gigantic, and it will contain a lot of superfluous
information. A good practical value for importing games is ECO-relative 20.
You can also include variations (i.e., analysis that might be included in the games),
but these are not included in the statistical analysis.

Imports the variations of a specified database and marks the moves as preferred
tournament moves. In effect, the program is learning from the analysis of the
grandmasters.
The analysis is incorporated as (green) tournament moves.
In the dialog box that appears you can specify how the individual lines will be treated:
Repertoire White: Every white move becomes a tournament move, black moves
are ignored.
Repertoire Black: Every black move becomes a tournament move, white moves are
ignored.
Moves that are annotated with a que st ion m a rk are not played in tournament mode,
and appear red in the book window.
! = Only move: This option makes moves that are annotated with an exclamation
mark the only moves that will be played. They appear green in the book window, while
all alternatives become red (i.e., they won't be played in serious tournament games).
