for black sea, a bounce makes most sense, though as turkey if you choose to avert lepanto you need two fleets in the med by 1902, which means taking bulgria to buildi in smy AND moving ank to con and on to AEG in 1901.
the only way to do this AND be safe from russia is to threaten sevastopol with the following: army smy -> armenia.
here even if you find black sea ocupied con and arm can bounce in ank, keeping all centers safe.
you only have to worry about austrian army rumania supported by black sea into bulgaria, possible but highly unlikely and serbia may be open to retreat while con could simply support bul to hold...
other boucnes.
tyrolia - Italy has a lot to gain from opening to tyrolia, and both austria and germany would prefer to avoid such an eventuality. It is entirely possible to see vienna and munich bounce in tyrolia in 1901, though the popularity of lepanto seems to reduce this occurance.
piedmont - italy can offer this to france and france is crazy at as much risk whether he goes for it or not.
burgundy - france & germany can arrange this or it can happen out of aggression, but
personally i'd prefer to order my army paris to gascony, for the obvious defensive advantage.
silesia/prussia - russia is better off assuming a german DMZ, even if it is unspoken. Common sense dictates that crossing this no-mans land in 1901 is suicide, but that's not to say those less sensible or more adventurous will not try it.
Russian army moscow - livonia, along with fleet stp - GoB, can facilitate a convoy to sweden in fall, and is a very nice variation of the usual northern opening. Along with warsaw moving east, russia can afford to send three units west and still holds some hope of taking rumania if turkey supports him.
