Ah, Sharp. Love his work. I read that a while ago and based a lot of my strategies in my early days on the site on his style of play. I'm very familiar with his Anschluss concept.
I'll counter by citing Paul Windsor's "Geography is Destiny" article [http://devel.diplom.org/DipPouch/Zine/F1999R/Windsor/dipmap.html]. In it, Windsor analyzes the layout of the map itself, and observes that Austria's most efficient victory requires the capture of all of Germany (see the list in Table 1), whereas Russia is perfectly capable of getting an equally-efficient victory without a single German center (see Table 4, where it's noted that Russia has six 'extra' centers for the most efficient win; that is, 24 centers lie within 3 spaces of Russia's starting SCs, which means to get 18 Russia can omit any six of those 24 it wants, including all three German centers).
There's another piece of information that I think bears noticing. Sharp's data comes from play-by-mail statistics from the 60s and 70s. When his book came out, a lot of people took notice and imitated some of his better suggestions, the Anschluss and tendency toward Sweden bounce among them. Windsor's article is from late 1999, and in Table 3 we see a list of win/overall/survival rankings. In Sharp's era, Germany was consistently top-2 with Russia in all three areas; since the adoption of his strategies, Germany's dropped to SIXTH in all three categories, while Russia has held steady at 2nd in wins and overall place while dropping to fifth in survival. Austria has gone up to 4th in survival, 3rd in wins and 5th in overall place, suggesting that the bounce only helps Austria and hurts Germany as well as Russia.
Looking beyond the stats, though, there's one other thing. Bouncing doesn't grant leverage or flexibility. In fact, automatically bouncing grants LESS flexibility and does nothing for leverage. It's the THREAT of bouncing - the move to Denmark - that creates the leverage on Russia. If you're automatically going to bounce Russia, then suddenly it is Russia who is free to do what he wants: he has no reason to listen to you and can act on his desires, without any care for yours.
