Turn 207: More freighters.
Interturn 207: Finish the combat at Liiruma. Realize I forgot to build biomes.
Turn 208: Build biomes for Liiruma. Spot an incoming near Tarka fleet attacking Shononu, due in 2 turns; move the Liiruma fleet to cover it now that they are done at Liiruma. This will delay additional attacks by a few turns but oh well; it should at least leave the near Tarka homeworld uncovered and relatively vulnerable to a counter-attack.
Far Tarka settle Lefkandi, which we managed to mine down to 2500 resources before they arrived. It will take them a while to terraform that puppy.

Next up is Kua'Gra, which has a Tarka colony fleet due in 4 turns. I doubt I can get it down quite that far before they settle it but we will see.
Amazingly, I don't build any freighters this turn. I am busy building extra warships and satellite defenses for Shononu, which can now have med sats thanks to Arcologies. I'll probably be back to freighters next turn though.
Interturn 208: Nothing.
Turn 209: Magnetoceramics is overbudget. Reinforce Shononu.
Interturn: Tarka fleet arrives at Shononu. We lose 1 gate and 1 DD sat. They lose 12 cruisers including 2 command cruisers, or about half their force.
Turn 210: Magnetoceramic lattices complete; redesign ships that need it to incorporate it. Give orders to settle Liiruma and queue up a bunch more freighters. Otherwise we're mainly waiting for combat at Shononu to end so we can use those ships to attack.
--------------------------
I have not chosen a next tech to pursue yet. Suggestions:
- Quick & easy, somewhat useful: Fusion warheads, Data correlation
- Economy: we could go toward stations for trade stations... it is a while yet but we will eventually mostly fill our trade network with CA freighters, at which point trade and research stations will be useful.
- Military: Incorporate Tarka so we can capture their civilians would be useful, and more chance of capturing anything they might have. Heavy drivers would be a useful offensive upgrade.
Suggestions for the Shononu fleet after it is done defending Shononu would be to split up into 2-3 fleets and attack a few useful places in our end of the barbell. The fleets attacking Ke'Lolum and Ke'Thalt should be arriving soon. Set formations how you like for these; make sure in the case of the Ke'Thalt fleet you use asteroid cover if it's available and PD ships if it's not. After the Ke'Lolum fleet takes out the Tarka pickets there and explores the world, it will need to be built up into a proper fleet with more support ships and probably a few extra combat cruisers as well in order for it to be sent against harder targets. The Ke'Thalt fleet should be amply big enough already for most things, depending on how stiff the defense at Ke'Thalt is.
I prefer going after the local Tarka before the Morrigi mainly because we will probably make the far Tarka angry by beating up the near Tarka, and I want the Far Tarka to have enemies closer to hand (Morrigi) so that they don't decide to pester us. Even though we can defend just about anywhere, I would prefer to avoid multi-front wars where possible.
