[BTS] Under which conditions AIs accept a city gift?

[Fine_Distinction]

I have read somewhere that an AI will accept a city gift is the city is no more than 9.5 tiles from its city (or maybe border distance?), with diagonal tiles counted as 1.5. I tried to test it in the WorldBuilder and indeed if cities where distant more than 9 tiles (straight line) from city center to city center it would show as City (Liberate). But they were more distant - 10, 11 tiles - an AI (I tested it on De Gaulle, who was please with me) would still accept them. Does it also depend on their attitude? their economy? other things?
Is it guaranteed that an AI would accept city that the game shows as "Liberate" in the dialog screen?

I wanted to try an espionage victory, so I need to settle couple cities now knowing that specific AI will accept them as gifts many turns from now. Since I am not sure what may influence the decision, testing in World Builder seems impossible. So far in Worldbuilder my cities are always accepted - but I remember it is not the case in actual games

One additional requirements that I know is that AI with number of cities lower than (I think) 4 would accept any city, anywhere.

Oh, that would explain why I could not get my AI to refuse - started when he had 1 city! Thanks!

so if they have >4, than it is just distance? or something else can play a role?

Another factor is culture. Better make sure the city you intend to give has zero culture, but it seems that you already do that. As to distance, for liberation the distance from that city to your capital must be greater than distance to the AI's capital. There was a post by Kaitzilla where he explored the matter.
