I once was told 10 years ago by a local GM friend of mine that the number of
openings which I was capable of remembering was not that important, but how good
I understood the position after the opening was over is really what count.
Therefore, the Quality of the opening lines whether it is 2,900,000 or just
59,000 good opening lines is better than having a larger opening lines as long
as those opening lines are free of errors and are the best for that particular
program.

PS: If it take closed openings to defeat good programs like Fritz 6a or junior 6
programmers should concentrate on programming those closed openings lines like
the stone wall defense used by Kramnik against Deep Junior, plus special ALS
Anti lock system in case other programmers apply the same technique in order
to make their programs perform better.
