There's a theory about Ainz and his Overlord race not being in sync. The overlord race is an advanced race, and some advanced races in D&D have much higher intelligence than humans do, like doppelgangers, elder liches, etc. Ainz overlord subconsciousness might be steering Momonga to make the best decisions whenever Ainz wants to do something. Ainz thinks it's just luck and barely remembers things, but that's because it's his overlord race aiding him.

Ainz spying on Jircniv to become a better ruler, while his overlord subconsciousness learning about Jircniv's plans, which eventually led to Jircniv being busted in the grand arena. Any other instances Ainz cannot explain for why things go well for him can be explained that it's his great intellect as an overlord aiding him.

When Ainz fought Shalltear or when he's completely confident, his race and personality are in sync.
