Classical Variation, Greco Gambit, Anderssen Variation

Arising from the Modern Line of the Classical Italian (5. d4 exd4 6. e5 d5 7. Bb5 Ne4 8. cxd4), this variation has Black give the check 8...Bb4+ rather than retreat with the more common 8...Bb6. Adolf Anderssen played it frequently. White must block the check, usually with 9. Bd2 and less often with 9. Nbd2, developing a piece in either case. The engine considers the position roughly balanced, and White scores somewhat better online.
