Opening database

Every named ECO opening, board-verified line by line: 3,812 lines across 149 families, each with a plan summary and a note on every move. Browsing is open to anyone: every named line has a page with its moves, its plan summary and up to its first 4 per-move notes, and every family has a page listing its lines. Reading the rest, and training a line move by move, needs a free account.
