changes in ai attitude before sneak attack

[Hawkster]

Commonly when the human player discovers certain techs first (eg gunpowder) the ai attitudes change - usually to icy or hostile often leading to sneak attacks.

I have also noticed that after this the ai attitude sometimes changes to receptive (usually after a tech trade or at least a fter a request for one from the ai) but I have noticed that when this happens it is a sure fire bet that a sneak attack is about to happen.

Why would the ai attitude go to receptive just before a sneak attack? Has anyone else noticed this....or have an explanation. It beats me why this would happen

I haven't really thought about the attitude changing, but I've noticed that "receptive" doesn't really mean anything. They seem to be as likely to attack as when uncooperative.

In Civ2 the AI changes their attitude all the time. Besides I'm not really keen on diplomacy so I don't notice anything.

I don't see a change in attitude. The AI can be very warmongering but they don't sneak-attack at receptive unless there's no peace treaty.
