You missread my message obviously, I said nothing about '8.d5 did bust Black'.
I said _in brackets_ '8.d5 _can_ bust Black in early stage .... in those
systems'. That is a completely different meaning.
Instead you wrote a lot of sentences just to agree in a somehow hidden way,
that 11...Na4? _in this game_ is bad, like I had already told.
Or did you mix 11...Na4 with 10...Na4? (10...Na4 does not exist here)
