Your start means you could get a surprise 2v1 very early on and knock a player out.
I have to disagree...
Between the 2 of us, there is only one quick grab (a moon) that is one jump from a HW, and it is not on the way to the enemy...quick grabs 2 or more jumps away are all away from the enemy as well....for there to be any chance of either of us rushing pink, at least one of us is going to have to go civ labs for colonization tech (which is not good at all for rushing) because of the ice and ocean between me and pink...
That is expensive and costly...add in the extra distance that green is going to have to travel to help me rush pink, and it would not be the early, unexpected 2v1 you describe....even if it did work, wouldn't matter...they now have 2 eco players (red and yellow) that can feed pink at any time, and both of those ecos are going to be capable of feeding long before me and green have the oceanic and are actually both ready to pick on pink (who, remember, has better eco than either of us individually)...
By the time me and green would be at pink's HW (and that's unlikely in its own right), red can swing in to help at a moment's notice and yellow can always hit us in the back (probably best to pick on the roids and moons above us)...
