The Cozio defense to the Ruy Lopez:
[FEN ""] 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nge7 4. O-O
The Cozio defense deferred:
[FEN ""] 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nge7
The deferred variation speaks more to me because I typically play a6. From the Opening Explorer, I think the best continuation for white is d4 followed by bringing the queen out to the center:
[FEN ""] 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nge7 5. d4 exd4 6. Nxd4 Nxd4 7. Qxd4
I'd like to know more about these defenses. What types of games do they produce? Is anyone known for playing them? Are they prone to traps or other tactical considerations?
