So I, still pretty new to and horrible at the game, with most of my "experience" coming from read AARs and the very few games with nations start already start as superpowers I played before, started a game as
Karaman, just out of interest. While I had some trouble fighting 4000 nasty particularist rebels,
Byzantium annexed my neighboring OPM,
Ramazan. I then declared on Byzantium and somehow managed (I think I got a bit lucky when 5000 of my men beat 5000 Byz. in Thrace who then ceased to exist since they couldn't retreat into Ottoman territory) to fully
annex their 3 provinces for just 3 infamy

. It's
1402 now. The problem is:
What to do now? The mediterranean minors are all guaranteed by scary things like France, Venice, Castille and Aragon

(well, at least the latter two seem to be busy with each other at the moment, poor Aragon once again being on the losing side) that would kill me within a blink of an eye, the exception being Sardinia who has no allies at all, but that's a bit far from home. The Ottomans have 5 times my army (should be better now that I went from 3 to 6 provinces, but still), they're scary. Maybe they will get lost in Timurid territory, but they also might decide to "reconquer" pretty much all my provinces since they have Cores on everything except Thrace and Morea. They might get missions against me, too. The two other turkish minors are no options, Candar is my only ally (other than one of these Arabian states that's not going to be very helpful), Dulkadir is both a vassal of he Timurids, bordering them and bordering the Mamluks, that means nothing but trouble. I have a CB on them, but I'd rather not use it any soon.
So what to do? I will have to be opportunistic, that is clear. Just wait until the Ottomans are busy with one of the hordes or maybe Hungary? Backstab Candar? At least try to prey on some of the mediterranean islands or comparable minors such as Montenegro and Achaea? Go to North Africa (Tripoli looks like easy prey, Tunesia is unfortunately being guaranteed by Morocco)? Do something weird and go after, say, Ireland? I really don't want to wait and lose my starting tech edge.
How dangerous is Venice, currently still the main power in the Mediterranean room, really? They do, including vassals, only have 6 provinces after all. What about Naples and Genoa (who already lost their Crimean territories), how strong are their armies usually at this point of the game? What about annexing the pope right away?
By the way, would it be a good idea to invest 3 stability into change my starting idea
National Conscripts to
Divine Supremacy (which seems better than Umam Sanctum to me), since I don't get the Jihad CB against non-neighboring infidels without one of these - what will be worth more, a 50% larger army or good stability and low infamy (and some bonus missionaries, currently I still have zero, on top of that)?
Wow, playing Karaman really requires a lot more thought than my first three games, the Timurids, Bohemia and Burgundy (the first and third for maybe 20-30 years, Bohemia for maybe 110), did. There it was just using your large army to stomp everything and just having to watch the infamy limit won't be exceeded, now suddenly these awesomely large and powerful nigh invincible armies are on the opposing side... on pretty much all opposing sides.
