One strategy for Hisn Kayfa centers around using large nations as a battering ram. Improve relations with Ottomans until they turn friendly and then ally them. Make sure you don't pick rivals until after you have an alliance. Once you have acquired an ally, this is where the fun begins.
The Basic Strategy
Pick wars where you target a war ally, not the war leader, and make sure your ally wants land. Take land in a separate peace, as this doesn't affect the Ottomans opinion of you.
Aq Qoyunlu is allied to Dulkadir, and Ottomans wants Dulkadir's land. Declare war on Dulkadir, promising land to the Ottomans. Once Aq Qoyunlu is full occupied, issue a separate peace to them where you take all their Sunni land. Then just white peace with Dulkadir, and funnily enough, The Ottomans will actually owe you favors for... doing nothing.
As time goes on, just answer CTA for Ottomans, prioritizing your favors to increase trust. It's entirely possible to have 100 trust with 50+ favors by 1500 using this strategy. This is important, as Hanafi and Shafi'i can turn Hateful due to the Ottomans fighting the Mamluks; having 80+ trust should stop them from turning hostile even if they hate your religious school. High trust likely decreases the time it takes for religious schools to go from Hate to Ambivalent and from Ambivalent to Respected.
Also, make sure you use the Provinces of Interest feature found on the Diplomacy screen. If you set them, Ottomans will give you those provinces even if they don't call you in on promise of land.
Don't worry too much about Aggressive Expansion, as you have the Ottomans at your back. It's unlikely that any coalitions would actually fire. By 1500, you can be a Great Power, and then, it's basically a slug-fest since you and the Ottomans are best buddies by this point. Have fun!
