Sun Tzu's strategy defines nine common strategic situations to which we must respond. They are defined as types of terrain: scattering, easy, disputed, open, intersecting, dangerous, bad, confined, and deadly. Each requires a specific response. Right now, the two candidates are in very different stages in their campaigns. McCain is on an intersecting terrain, which means that he has the opportunity to solidify alliances. Obama is on bad terrain, which means there are a lot of pitfalls that he must avoid. Needless to say, you want to be on the former, rather than the later.
