I whipped Carthage for 3 pop to complete the settler. I couldn't let toku steal that jungle spot. I managed to settle Kerkouane to grab 2 bananas, 2 spices and grassland cows.
After trading Currency to Cathrine for Construction, I build 2 catapults in Utica, just in case Toku gets some crazy idea of bringing SODs into our border. He is already annoyed with me for different religion, but he doesn't have enough on his hands yet.
I made a mistake and revolted to hereditary rule, thinking it would improve my relations with Cathy, but I didn't notice she is not in hereditary rule. I didn't need the happiness yet and could have made the revolt together with bureaucracy.
I trade mysticism to toku for 60 gold and beg for 40 gold from Sury, which give me a few turns of 100% research.
Next tech was code of laws, which I traded for Calendar.
Then I went civil service->paper->compass. It might have been a mistake to delay philosophy (Sury got it first). I revolted to bureaucracy+caste system to get a faster GS, but now I fired the scientists in carthage to work tiles and build a few more settlers.
After trading world maps with everyone except Toku, I can see the world and there is still some unclaimed land:
I have a settler that has just arrived to the point marked "Next city". It should be a good production site and will have decent commerce from trade routes.
I am building another settler in Carthage which will settle here (marked "next next city"):
I managed to get another great scientist and he sleeps in Carthage. After Philosophy I will revolt to pacifism and get another GS in Carthage, to bulb education.
Current Tech Status:
Our cities:
I urgently need more workers and perhaps another settler for a filler city between Kerkouane and hadru
I can also start to build a lighthouse in Utica and chain irrigate it so it grows some more. 2 coast tiles will give almost the same as gold mine and let the city grow.
My long term plan is to tech ahead and attack Toku.
My biggest fear is getting attacked too early (Toku, Sury and Cathy - we cannot trust any of them right?), so I am taking care of building enough army to defend myself (slowing my expansion and infrastructure) and for this reason I think I will give up the marble spot north and let Toku have it.
Hopefully I can bribe Sury to a war with Toku soon, so it will give me some safety until I have a tech lead.
I am still not sure if I want to go to a rifling/draft war or to a cannon/grenadier war, or maybe take advantage of the UU and build some horses which will be upgraded to cuirassiers later with a free flanking promotion. The empire is low on production, so a lot of whipping and/or drafting will be needed. Luckily I have a lot of luxury resources on this map.
Diplomatic status:
The hindu block are fairly good friends, I would be happy to try to do something to break it. In any case, they seem to be behind the advanced Confucian block (that's us!!)
POTENTIAL TROUBLE
Hmm... I just looked again at the tech status and noticed that Isabella and Cathrine have theology, while Sury doesn't. This means that we will have a hindu AP in this game. It might be worth it to switch sides and go to war against Cyrus and Sury. Let's hope Hinduism spreads to us soon, because I am really afraid of "declare war on the infidels" decision, which will result in a dogpile by Cathrine and Toku.
Diplomacy is not my strong side (except begging for money - I am good at that

), please help.
Any advice is welcome, especially if there is something important I am missing.
