Currently in the Computer Chess Championship (chess.com/ccc), we're running a bonus event! Stockfish and Lc0, the two top engines in the world, are playing every line in the Encyclopedia Of Chess Openings. Even at 1|1 bullet, playing all 2014 of them takes a while.


And boy, are there some bad ones.


So in the spirit of "Random Bad Chess Openings," here's a quiz for you. I've listed a bunch of ECO opening names... but some of them are made up. Can you pick out the ones that are real, and the ones that are fake? (Post your answers in the Comments!)

  1. Ruy Lopez, closed, Kholmov Variation
  2. Scotch, Ghulam Kassim Variation
  3. Nimzo-Indian, classical, Kazakh Variation
  4. Ponziani, Caro Variation
  5. Caro-Kann, Ponziani Variation
  6. Ruy Lopez: Morphy Attack
  7. Ruy Lopez: Morphy Defense
  8. KP: Proto-Mongoloid Defense
  9. KP: Mongoloid Defense
  10. KP: Neo-Mongoloid Defense
  11. Global Opening
  12. National Opening
  13. Valencia Opening
  14. Giuoco Piano: Greco Variation
