If you do want I will agree then, just to let you see I was not kidding about my situation.
I believe I can still hold for a few turns, as long as your other fleets are not on active duty in my systems. Once they arrive... They will be able to wreak havoc behind my lines, and will effectively prevent any decent effort at colonizing. (Do remember I need quite a few turns before being able to make a benefit from these gas planets. And even then, I don't believe I can afford to develop two planets at once before you arrive, let alone ten.)
So, if you would like to finish me, go for it, but I am still not convinced at all I stand the slightest chance, either in the short run or in one or two years. (Incidentally, my carriers were fleeing to hold my main systems, not intercepting your own fleet. That was the first idea at least, perhaps I should just send them to guard this front)
