1. checks are not indicated - an ECO quirk
2. I have been sparing with the qualifications (lines with and without
certain moves) as they are implicit in the classification anyhow.
3. I have typed all the castling moves with capital 'O's not zeroes (0).
4. Volunteers to proofread take one step forward.
5. English variation names added Spring 1997
