Ok I played 20 turns until the completion of Alphabet, and we also have a settler ready to found before Refar hits enter. I did not switch to Hinduism yet, but I think it's definitely worth considering in the next set, along with building more military.
The Dutch empire is glorious!
We've been doing a nice job grabbing cities, so I focused on infrastructure this set. On the first turn I whip a couple workers and the long delayed lighthouse in the Hague. I build a couple more workers over the following turns. We now have libraries in Amsterdam, the Hague, and Utrecht. Our southern two cities have their most valuable tiles improved and connected.
Here's how our GNP looks, I caused the lowest point in my first turns, and the burst at the end is the only time we are actually researching Alphabet. (I thought I got Korea's chart too, feel free to readjust our espionage.)
I moved Tatran's settler north to found the crab city, which is easier to develop at the moment. It also lets me feel safe opening borders with Napoleon. I timed a work boat to reach it at the border pop, but we lose it eventually to the new patch's pirates.
I explored our neighbors' land, opening up trade routes in the process. Unfortunately Ragnar grabbed the sugar barb city to our SW. I had a hopeful moment when my axeman saw there was a barb archer ready to attack its lone warrior defender, but Ragnar held the city.
Here's the rest of his land (and I found Egypt west of him)...
Near the end of my set, he grabbed the pig from us...I had a settler 3 tiles away heading there.

My apologies for losing the food for silk coastal city. But we have a very nice site that makes his city useless. I have a settler ready to found it now if you guys agree, along with a team of workers to connect it and improve the pig. I would suggest converting to Hinduism before the borders pop. We can still grab the silk with the next settler (or found the nearer coastal site instead).
Here is Napoleon's land...
I prefer to let him keep his land and focus our military efforts west. Notice the barb galleys. I have a galley for defense in our capital, and an extra workboat ready next turn. We need to whip a galley in the Hague too, and ultimately Metal Casting for triremes and the Colossus (but Egypt has MC already so this may be lost cause).
Diplomatically I think we want to use Napoleon and Ragnar as puppets against Charlie first, and then the Jewish states. But Charlie doesn't know he's supposed to hate us yet....
He also got a 'heroes of the sword' event for promoted swords, and has protective archers, so he isn't an ideal enemy by any means.
(Btw, we have some mines of questionable legality, one is seen above. Are we saying forest can't spread diagonally so they're ok?)
I realize now I forgot to cancel Napoleon's free clam, we can use it to buy wheat instead if we choose. Here is the tech situation - Korea got Alphabet before us, but I declined to trade the religious techs...
Ragnar is willing to declare war on anyone, but we can't buy him with just writing. I have the tech set on Monarchy again since we have beakers invested, maybe we can use that to trade for Math (I haven't thought much about this yet honestly). We are in good shape in terms of happiness right now, but there is some whip stacking. What I really want is Metal Casting though.
