Bogo-Indian Defense
21 named lines in this family, ECO E11. Every one of them opens 1. d4 Nf6 2. c4 e6, so the notes on those moves are 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.
