1) Since "hot" war is not likely to start in the first 4-6 years of the game, build two bases every year for those years. Then, spy every year thereafter to insure a first strike and a good awareness of potential targets. 2) Since the more bases of a type that are available to you increase the likelihood of their automatically activating (and saving you a game turn), build in a balanced manner. 3) Don't negotiate unless you have a clear-cut advantage.
