Snipped and reposted from another thread:

The original post had 9.f6, which is clearly illegal.

The line through 8...d5 *is* in Hiarcs' opening book.

I didn't create the opening book, so take my response with a *pillar* of salt.
Historically, there are three games I found in which the line through 8.f5 was
played. Statistically, Black scores 67% in this line (two wins, one loss).
However, the line was probably put in the book so that Hiarcs knows what to play
as *Black* in this line. According to the book probabilities, Hiarcs has equal
chances of playing 3.Nf3 or 3.d4 as White. The d4 gambit line should probably
have been weighted a bit higher than the alternative. In the 3.Nf3 line we're
discussing, 6.0-0 would have been better than 6.Nh4 (statistically speaking).

I've not yet seen any chess program in which the opening book didn't have a few
"holes" (in fact, I once covered this in T-Notes last fall); we usually hear
about them pretty quickly after a program's release. This would appear to be one
such case. My guess is that the person who created the book was more concerned
about what Hiarcs should play as Black that he forgot to cover White in this
line.

Remember, though, that this *is* just a surmise on my part.
