BCO is a chess abbreviation. In practical terms, it refers to an abbreviation for Batsford Chess Openings, the 1982 openings reference book by Raymond Keene and Garry Kasparov. The second edition (1989) is often called BCO-2. Compare ECO and MCO. If you see it in a database, book, or tournament page, treat it as shorthand and check the surrounding context.
