You can set the number of games you want to copy.
Length
Crucial for the size of the resulting tree is the length of the variations which are put
into the tree. It is not very meaningful to put entire games into it, so you should
truncate them at a specific point.
ChessBase allows you to limit the length of the variations in two different ways.
1. You can specify that the absolute length of every variation should be exactly “n”
moves.
2. It is usually much more sensible to limit the length of 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 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 adding games to the tree is the default of ECO + 20.
Variations
You can also include variations, i.e. analysis that might be included in the games. But
these are not included in the statistical analysis.
