Been going through MCO 9 looking for lines that finish with 'unclear' or something similar.
Page 283 has a line ending here after 12 moves.
Saying White's attack should come to nothing quoting Gelder - Loman 1919.
I cannot find it the game (yet) but I do know the player's were active
around about the same time.
I was looking at the position and wondering about the phrase:
"Saying White's attack should come to nothing."
Perhaps hinting that White's attack did come to something through plausible bad play.
If in the above position Black plays 12...Bb6
Did White play 13.Qxd6?? and Black missed 13...Bxf7+ and took the Queen.
(I've been looking at RHP games for far too long - all I can see are bad moves.)
Here are the moves leading up to the position in MCO 9.
1. e4 e5 2. Nf3 Nc6 3. Bb5 Bc5 4. O-O d6 5. d4 exd4 6. Nxd4 Bd7 7. Nf5 Bxf5 8. exf5 Qf6 9. Re1+ Ne7 10. Bxc6+ bxc6 11. Nc3 Qxf5 12. Ne4
Here is an RHP game where White plays a sound pseudo Queen sac Qxd6
followed by a Knight check winning back the Queen. (move 14)
