(0) 1400 AD - Clearly, gearing up for the next war is a priority here. If Greece decides to attack now, we could be in big trouble. I spend some time shifting some defenders around to leave as many cities as possible covered. I set some of the core cities to infantry for now, so that we can at least defend our core's border. A few core cities, and the celtic ones, can do artillery.
(1) 1405 - Rush temple in Tsingtao. Begin collecting artillery and cavs in the East. The eastern cities will probably give us more land for less losses than the other Greek ones, although they won't do much population-wise.
(2) 1410 - The resistance ends at Canton. We rush a temple to celebrate. Beijing's resistance ends, but the city riots. We also get temples at Tamuin and Dalandzadgad.
Hmm, so much for "gearing up":
We were NOT ready yet! Those bastards used our ROP to ride the rails up to Tenochtitlan this turn before they declared, so they just walked right in to the undefended city! They also capture Malinalco and several workers. In happier news, our one fortified jag kills an attacking cav. He promotes to elite, and he deserves it!
(3) 1415 - Well, the assembled artillery and assorted units might as well do something. They march towards Babylon. I don't really have anything that can pick units off in our core- I change some build orders to cavs. We should have a few. I pick off some Greek cav units. Oh, our palace moved to Teoti, so we now have our forbidden palance in our capitol.

I'll try to fish for leaders when possible.
(4) 1420 - Re-capture Tenochtitlan. Capture Shanghai. At some point in here I upgrade some of those old jags to guerillas. We are very short on units at the moment, and those will help a lot.
BT - The Greeks capture Tula and raze Teayo. Visions of losing by domination during my turn run through my head.

Both of those cities were guarded by a single infantry. Increasing the defenders in those cities would have meant leaving some undefended. Since the Greek cities down there are mixed in with ours, there's really not a safe city to leave undefended. OTOH, in our core, now that we're at war, I can leave the backlands undefended now as long as I can keep the incoming units under control.
(5) 1425 - With those thougts in mind, I have a rudimentary strategy. I'll try to take Greek cities starting from the east to help us build an identifiable front and backlands. That should help us stretch our defenders better. The only problem with that idea is that I don't have a lot of units out there, and new production from the core can't get there safely at the moment. I guess it will start slowly, but it should pick up. We do have a stack of artillery.
The core, on the other hand, will focus on defense. I'll try to pick off the units they send without really going for land for the time being. Security in the core is still very iffy at the moment. Hopefully I can minimize losses and take out there units so that things will improve.
There is a Greek cav SOD that can get to Darhan and Ulaan next turn. I move defenders up from the back lines. Also, war weariness is around 35% already. Lux tax needs to go to 20%. I bombard Babylon, but hit everything but the defenders.
(6) 1430 - The Greeks have moved their stack up, but not attacked this turn. Perhaps the lightly defended cities in the back have attracted them. Still, I don't think it's puppet strings, because I was only moving units up to provide needed defense, not to bait.
Anyway, I kill all 10 cavs. First, artillery, then cavs, then guerillas. I needed a few infantry to finish the job. We capture Babylon and Sistine. I have to draft at a Mongol city.
War weariness is up to 52%! While it may be kind of tolerable (if you don't mind huge lux tax or starving cities, or both), it's not going to get better. I don't think anyone here wants 20 turns of peace anytime soon, and even that might not take care of it. If we were anything but religious, I would have stuck it out, but as a religious civ, it seemed clear that the time had come for Monarchy. I hope you guys don't mind. With those cavs gone, we can spare a turn of production right now, so I go for it.
Things were bad enough that the cities are already in much better shape during anarchy.
(7) 1435 - We become a Monarchy. Lux tax can be turned off, even in empty cities, which is such a relief! There's not a whole lot else to do this turn, except to pick off a few Greek units on the mainland. I also bombard Ur.
BT- Greeks land 4 cavs by undefended Tenochtitlan. There are two more full boatloads coming next turn.
(8) 1440 - Redline and kill the landed cavs easily enough. Our fighting force in the E is virtually nonexistent. Maybe I wasn't patient enough at Babylon considering we don't have reinforcements that can come. Right now, units from Ur can still ride some rails up and threaten the north, but that should change soon. I rush some temples and a few units to help us take Ur.
BT- Those two boats headed for Tenoch unload only 5 cavs.
(9) 1445 - I yellowline Ur, which has 3 infantry. I think we can take it. I attack, and kill the three infantry, plus a wounded cav that had been left out. That leaves a wounded cav holding Ur, but I have nobody to hit it with. Next turn.
At the core, we are able to kill the 5 cavs by Tenoch, and 1 by Darhan, losing one guerilla. I think I killed a couple of infantry, too, but didn't note it. I shift production focus away from cavs and infantry in most places to artillery. There's mostly Greek infantry in the borderlands now, and there's no point in attacking them without enough artillery.
BT - Two cavs land by Tlacopan (units are now healing in Tenoch, so it's not undefended but Tlacopan is).
(10) 1450 - Two cavs are easy enough to pick off. Once again, I failed to note if I killed any infantry, and already the memory is fading, but I think I got a couple.
Ur still has only the cav showing, so I attack. We capture Ur and Bach's.
The extra artillery head over to bombard Tula this turn. I didn't move a "spy" cav in to see the units in there until after, for some reason, but I do know that there was a wounded infantry on top when I did peek. Ur seemed more important because it's can help to keep the roads open to the north.
The Greeks are bombarding like crazy with ironclads. This should be fine as long as we keep resource access up to China.
Speaking of resource access, if we closed two tiles out of Ta-Tu, I think that would end Greek rubber access in their eastern cities. I didn't check to see how much trouble that would entail, as far as what units would be available to go to Ta-Tu.
We are first in land, but second in population. My guess is that population will hold us back for domination more than land area will. If we have to crack their core anyway, conquest starts looking more and more appealing, imho anyway.
It was looking scary for a while, but I think things are starting to turn around now. Good luck!

Edit- I was interested in looking at the 1450 minimap vs. the 1400 one. Since I thought some others might be as well, I figured I'd post it.
