Hard to say but without Prussia as an ally i'd imagine Russia would lose to the Austro-Ottomans.
No, they would be at war with them over ottoman territory. As I said Frederick the great is the one who averted this.
BTW, why didn't Russia and Austria still go to war with each other over the fate of the Ottoman Empire even after the partitions of Poland?
No actually. River travel was problematic in itself. Some river baron could throw some chains across and deny you access if you didn't pay whatever he felt like demanding. This is why Austria didn't exploit its river connections to the Baltic and black sea. Hostile states would block them. If you didn't have a land connection you had to be friendly or imposing to the connecting states.
Is a Fascist Russia likely to be an expansionist power or a status quo power?
Though you could also respond to the thread which involves a Russian abolition of the Pale of Settlement in the late 1800s.
