a possibility would be to give the ai a second map and game struct,
which houses educated guesses, about troop concentrations in enemy
cities for example. Another example would be seeing an enemy unit coming
out of unknown territory and then assigning probabilities about the
terrain type (!ocean) to the unknown tiles.

yes, yes, but I'm looking at a point in time where the AI doesn't have
any choice because it ain't connected to the server. It can only see
what it sees. Coding new stuff that takes advantage of the current
omniscient ability is not a good plan.

whatever it is, the its_time_to_invade() function should be on the
