The crux of the matter, for me, is whether 6...Qd6!? and the Vienna hold up and suit me, but my initial impression is very positive. I've played the Noteboom/Triangle and Semi-Slav in the past, so I'm familiar with similar positions, and I see many of the less critical lines as improved forms of the Noteboom or Semi-Slav. I'll have to learn the Vienna variation now, but, I've been looking for a new defense to 1.d4 for years, and this seems to be it.
Just as a quick sidenote:
- If you do turn out to dislike the Vienna, you can of course always play ..h6 instead of ..dc4:, still a perfectly valid line that's played at 2800+ level (although I suppose its most recent outing in Aronian-So isn't the best advertisement). Shying away from the Vienna doesn't mean you have to give up the Ragozin as a whole!
- If you turn out to not-hate the Vienna, but are unhappy with some of the selections, Gustafsson has an excellent video series on the Vienna proper on chess24, which transposes into the Ragozin-Vienna lines if White so chooses. Personally, I much prefer the lines Gustafsson gives over those in the Pert book, and just use Pert for the Ragozin proper.
