A00
Ware Opening
7 named lines in this family, ECO A00. Every one of them opens 1. a4, so that move's note is written once, just below, instead of once per line. Under each line you get its moves and the sentences it adds that this page has not already printed. A line's own page carries up to its first 4 per-move notes in full.
