As eagle-eyed readers of the screenshots posted above will have noticed, I took a rather large gamble at the beginning of this turnset.
I spent about half an hour just staring at the map, checking all the little details, and mulling things over. Then...
My thinking was that, with Toku having only just settled to the NW, I could get another settler up to claim the gems in time. And, with IW still a fair way off, I could really use a workable third city in the meantime.
But this was a double gamble: since I had to get a new settler built asap, I could end up missing the GLh as well as the gems city. So this was one of those occasions where I felt the need to slow it right down, and concentrate very carefully on my micro decisions.

Worker done in Akkad (next: Granary).
1275bc (109) Babylon switches to Settler (chop).
1250bc (110) Babylon continues GLh (growth).
1200bc (112) Babylon continues Settler.
1150bc (114) Monument done in Dur-K (next: Worker).
1075bc (117) Settler done in Babylon (next: Worker).
1050bc (118) Whip Worker in Babylon.
1025bc (119) Worker done in Babylon (continue GLh).
950bc (122) Nippur settled. Nippur starts Monument. Akkad whips Granary.
Damn that was close!

Granary done in Akkad (next: Galley).
825bc (127) Worker done in Dur-K (next: Granary).
650bc (134) Writing complete. Tech Mathematics.
625bc (135) Galley done in Akkad (next: Barracks)
600bc (136) Whip Monument in Nippur. Whip GLh in Babylon. (Yes, I was that worried about missing it

).
575bc (137) Monument done in Nippur (next: Library).
Great Lighthouse complete. Babylon starts Barracks.
525bc (139) Barracks done in Babylon (next: Sword).
455bc (143) Barracks done in Akkad (next: Axe).
Granary done in Dur-K (next: Barracks).

395bc (147) Axe done in Akkad (next: Bowman).

I now had enough units on the way to capture the barb city, Burgundian. I used my Galley to ferry them over a bit quicker:
After delivering the troops, the Galley went off to explore the mysterious east.
350bc (150) Sword done in Babylon (next: Library).
335bc (151) Mathematics complete. Tech Construction.
320bc (152) Bowman done in Dur-K (next: Bowman). Whip Library in Babylon.
305bc (153) Library done in Babylon (next: Axe).
Burgundian captured. Burgundian starts Granary.
One Axe died (at about 65%). I chose to keep it, since HC would surely steal the spot otherwise, and I didn't want to waste time on a Settler. This is me in full warmonger mode - screw the long-term, I've got a Tokufish to fry...
On that note, the conquest cash helped to speed up Construction, the first of my two tech targets.
290bc (154) Buddhism spreads to me. I convert straight away, to curry favour with the eastern block.
260bc (156) Bowman done in Akkad (next: Library).
245bc (157) Kublai goes recon crazy:
Three scouts?! And it's not even like he could've popped one from a hut. Idiot.
230bc (158) Bowman done in Dur-K (next: Axe).
215bc (159) Great Merchant is born in Babylon.
At first I was disappointed not to get the GSpy I had been expecting - I'd planned to use him to scope out Japanese territory in advance of my invasion.
Then I realised that the GM could bulb Currency - a bonus trade route in every city, a step towards CoL and CS, and a chance to beg cash from my Buddhist buddies.
170bc (162) Axe done in Babylon (next: Settler).
Two interesting developments here. Firstly, Darius has enough on his hands - could I be his target? Secondly, guess which AI was first to Alphabet...

Is there no limit to his foolishness?
155bc (163) Construction complete. Tech HBR.
Axe done in Dur-K (next: Cat).
110bc (166) Whip Library in Akkad. Whip Granary in Burgundian.

65bc (169) Horseback Riding complete. Tech Alphabet.
Cat done in Dur-K (next: Cat). Galley destroyed by barb Galley.
Borsippa settled. Borsippa starts Granary.
(I forgot to take a screenie when I settled it).
50bc (170) Whip Cat in Babylon.
35bc (171) Cat done in Babylon (next: Stable).
5bc (173) Library done in Nippur (next: Ele)
10ad (174) Cat done in Dur-K (next: Ele)
25ad (175) Alphabet complete. Tech CoL.
Over the next few turns I traded for
Meditation,
Polytheism,
Priesthood, and
Monarchy, whilst maintaining a very healty lead.
At this time I also came into contact with the fifth AI, and the cause of Darius' WHEOOHRN:
He's already captured Susa. I briefly gifted Iron to Darius to help fend off the Zulu - we don't want that guy getting too powerful...
40ad (176) Stable done in Babylon (next: Ele). Switch to Workboat in Burgundian. Whip Granary in Borsippa.
55ad (177) Granary done in Borsippa (next: Barracks). Whip Workboat in Burgundian.
70ad (178) Workboat done in Burgundian (continue Library). Shaka and Darius make peace.
85ad (179) Ele done in Dur-K (next: Ele).
100ad (180) Kublai proves the world is round. Whip Ele in Nippur. Switch to Axe in Akkad.
115ad (181) Code of Laws complete. Tech CS.
Ele done in Dur-K (next: Cat).
Ele done in Nippur (next: Bowman). Whip Axe in Akkad.
130ad (182) Ele done in Babylon (next: Ele).
Axe done in Akkad (continue Cat).
145ad (183) Cat done in Akkad (next: Lighthouse).
Cat done in Dur-K (next: Ele).

175ad (185) Ele done in Dur-K (next: Axe).
190ad (186) Axe done in Dur-K (next: Cat).
DoW against Toku:
205ad (187) My stack at Tokyo, and reinforcements on the way:
Tokyo is captured with no casualties:
Tokyo starts Monument.
250ad (190) Bowman done in Nippur (next: Bowman).
Kyoto is captured.
This time I lost a Cat and a Sword, the latter at about 95%.
Kyoto starts Monument.
265ad (191) Barracks done in Borsippa (next: Bowman).
280ad (192) Whip Monument in Tokyo.
295ad (193) Cat done in Dur-K (next: Ele).
Monument done in Tokyo (next: Barracks).
310ad (194) Granary done in Babylon (next: Ele).
Lighthouse done in Akkad (next: Cat).
Bowman done in Borsippa (next: Cat).
325ad (185) Civil Service complete. Tech Monotheism.
Bowman done in Nippur (next: Granary). Whip Cat in Borsippa.
Osaka is captured with the loss of one Cat:
I kept it, and started on a Monument. My first GG was born during the attack, but I've yet to do anything with him.
After taking the third city, I decided to take peace with Toku:
It was a tough choice, and would cost us another demerit with the Buddhists if we chose to attack again (which I almost certainly would). But it did give me a chance to heal, and to get some reinforcements (esp. Cats) in position without worrying about counter-attacks. The cash is nice as well.
340ad (196) Monotheism complete.
Cat done in Borsippa. (next: Cat). Whip Cat in Akkad.
Adopt HR, Bureaucracy and OR - 3 turns of Anarchy.
395ad (199) Anarchy ends.
This is where I decided to stop. There's a GG waiting to be used, and there are several different tech paths we could take. And, with 6 turns left of enforced peace with Toku, there's time to position the troops for another attack (if so desired).
