So I've got a preliminary set of steps that just might work. So far I've still ultimately died or ended up in untenable situations, but I've at least got a set of steps that saves you from the early Crimea DOW.
1. Send diplomats: Mil access in Trebizond, Improve Relations with Circassia. When Treb diplomat returns, Improve Relations in Georgia.
2. Ship troops to Trebizond. This is so you can link up with your primary allies later.
3. When Trebizond asks for alliance, accept. This is the only way to prevent Crimea from DOW'ing within the first few months. Reject RM.
4. Alliance with Circassia, RM. Georgia when they'll accept. Mil access from both. March troops to Circassia.
5. Fabricate claim on Kaffa.
6. When Trebizond calls you vs Qara Qoyunlu, dishonor alliance. It's not feasible to win this war, even with Georgia's help.
7. Once Georgia is out of debt, wait for an opportunity to attack Genoa; ship troops back to Theodoro if one opens. Once war starts, fabricate claim on Crimean territory.
8. If Crimea DOW's before an opportunity, make sure your army in Circassia is set to allow army attachments so you can fight with the entire stack of your troops, Georgia, and Circassia. Try not to fight on Crimean soil.
That's where I am right now. If anyone has been more successful or has their own strategies, post 'em up!
