Subject: ECO Code System Question
I have a question about the ECO. Whats the logic behind the organization of
the openings? For example, if I want to find an opening that I don't know
the name of whats the quickest way to find it? These question are with the
book in mind not a computer Database.

Generally, the letters are for different types of first moves.

Within each letter, the "90-99" openings are thought to be the sharpest main
lines, while the "9s" (99, 89, etc.) tend to represent the current main line
within a variation.

For example, B99 (89?) would be the Najdorf Sicilian's main line, because
that is "sharpest" in the view of most GMs, etc. A59 might be the main line
of the Benko for the same reason.

couldn't find a general pattern. Thank you.
