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. Your Sicilian line was address in another thread (it's down toward the bottom of the page -- something about Fritz in 60' games). -- Steve Lopez
