Here the analyzed (by KomodoDragon 1.0, 15 seconds per move on a QuadcorePC) lines out 
of the Megabase 2020.
Huge eval-interval of [-1.99;+1.99]

Not for using (contains very bad lines, too), but for filtering lines out for own opening-sets.

The Annotator-Tag contains the Eval of KomodoDragon and the search depth.

eval is always 3 digits and + or - (+001 (+0.01) or -133 (-1.33) for example, from
the point of view of white.

Use (for example) ChessBase or Fritz for filtering:
Search "eval=+10" to find all lines with eval [+1.00;1.09]

If you want a bigger eval-interval, it is recommended not to search for the evals you want, but
to delete all evals, you do not want, because otherwise the lines are sorted by the evals.

Example: Find balanced openings in an interval of [-0.20; +0.30].
If you search and copy "eval=-02", then "eval=-01" and so on, the lines are sorted from
-0.20 up. To avoid this, delete all eval out of the raw-data file, you do not need, instead:
You have to delete "eval=-19", "eval=-18"..."eval=-03" and then
"eval=+04", "eval=+05",..."eval=+19".

This is more work, of course. But the lines in your final pgn-file are not sorted by eval, now!
