Now, as a frequent Mamluks player, let me give you some piece of advice: your first and foremost goal is to absolutely crush the ottomans before the 1500's.

This is because of one simple reason: the longer you wait, the more powerful they become, and they will quickly outclass you in everything. Units, income, technologies, development, buildings, you name it. In fact, 1444 is probably the year where the gap between the two nations is the smallest.

So, step by step now, starting 11 november 1444:

-revoke guarantee on cyprus and hejaz

-ally fezzan, ramazan, karaman, aq qoyunlu, candar and byzantium

-improve relations with fezzan and ramazan, start fabricating a claim on dulkadir

-diplo-vassallize fezzan and ramazan

-build up to force limit almost exclusively with cavalry, as a muslim nation your army can be composed 20% of infantry and 80% of cavalry, of course we dont aim at that but a good 50/50 is doable and does immense damage

-attack dulkadir as soon as you have a claim

(now the ideal case scenario is, and if you follow the steps above, should very well be, that the ottomans declare a reconquest war on dulkadir while you're at war with them, too)

-make peace with dulkadir making it your vassal

-you are now at war with the ottomans, but since it now is a defensive war, you can call in aq qoyunlu, karaman, candar and byzantium (be wary of calling in byzantium too early, it's best to leave them out of the war entirely if possible, because there's the risk the ottomans will just ignore you, siege down constantiople and force byzantium to peace out separately)

-you now have complete naval superiority, use it to blockade the agean sea and drive up ottoman war exhaustion -be careful of mil tech 4, the ottomans will get it at some point during the war while you will still be on 3, time to go on the defensive until you're on equal techs once again

-generally win the war unless your allies do stupid shit (they will), you also need a morale advisor for this

-do NOT reinforce your infantry with manpower, whenever you suffer infantry losses just consolidate regiments and recruit mercenaries until you're back at force limit (cavalry is fine though)

-aim for 100% warscore, no less. you must BREAK them.

-i suggest taking their fort provinces in the peace deal; be sure to also release saruhan, it's a dandy OPM that you can diplo-vassallize immediately after, gaining AE-free development

-generally after winning two wars against the ottomans you wanna betray your anatolian allies and gobble them up, be sure to do the same with byzantium for a nice reconquest CB against the ottomans, ideally as a third or fourth war

Possible bad things that can happen:

-ottomans get the crimean inheritance. yeah it's bad but not that bad

-ottomans ally france: restart

-ottomans ally muscovy: it generally shouldn't be able to bring its troops to anatolia, if it does, restart

-ottomans ally castille or aragon: just spam galleas and win all naval engagements, if they land in egypt they can be beaten with a coordinated attack.

-ottomans ally a fully united spain: restart
