I'm 60 years old, it's year 988, and I hold 3+1 Kingdoms.
The succession law is Confederate Partition, and there's no way I can enhance it to a better Partition (so destroying titles would be useless).
Can switching all of the secondary kingdoms to Feudal Elective help me? That is, how can I understand if I have a chance of winning them, rather than them going to random Dukes not even related to me?
