I put this in the game that just ended, but I think Russia should play a northern or a southern strategy without worrying too much about stp or sev, whichever is excluded by that strategy.
Since Turkey most often goes for the Jugger, I tend to play (About 80%) a northern strategy, opening to stp and fin/both. I move to gal for the bounce or gain, and bounce black sea.
Typically, I can still secure rumania. If gal bounced, I will move with the fleet and let Turkey take the black sea, while moving war to ukr. If gal didnt bounce, I will support it in.
In the north. you almost never can bounce England in norway, so dont try. Go to finland.
For builds, the key is not to build another fleet sev, as that will kill relations with Turkey. If you have two builds, Im partial to a mos, f nc stp. If only one build, I build a mos. Clear signal to germany you want to work with him. And Germany will likely have be focused on the netherlands, at least with his armies.
Beyond these opening moves, everything depends on the board. Indeed, even autumn 01 depends on whether the turk is armenia.
If you propose specific opening boards, I can suggest what I would do. But like you, I admit that Russia is my hardest country in boat.
