A possible translation could be:
" This move, decribed by Anonimo Robenese, could possibly occur. But if white would take Nc6 immediately, black then will be a bit better developed with 3. Ng8 to f6 instead a7 to a6 because of his threat towards e4." Hope this helps.
I'm having trouble making out a few words in this passage from Handbuch des Schachspiels (1852).
It is a footnote to 3...a6 in the Spanish.
Can anyone help?
