We have only 3 Warriors, all of whom are off scouting, and barbarian warriors are showing up already, so I schedule a Warrior(6) in the capital. Poverty Point should be safe because of the fog-busting AIs are doing.

We are surprisingly competitive accoring to Demographics screen, but this will change once AIs start to improve their tiles. In fact, Korea has only 1 city so far. (According to their trade screen.)
As expected, Portugese borders expand the next turn, putting 15% of their culture onto each of the forests north of Poverty Point, and taking over most of the other forests in the area.
It also looks like our "peninsula" is actually half of our entire continent. So if we can secure this entire area, we'll be in great shape. There is copper in the north that appears to be on the coast, but getting it would be a bit of a reach.
Next turn Portugese culture on our forests is up to 24%, so we might not be able to chop either of them. I also see Portugese archer north of our city. I decide not to tempt Jao with such a perfect target and recall nearby fortified warrior to defend the city. (I've seen AI start wars just to steal a worker, and an unprotected city is too tempting, espcially when we are by far the last in Power rating.)
Writing comes in in 2000BC and we go on to Math, due in 30 turns. I immediately open the borders with Korea, but leave the OB with Jao to team's discussion. I think we should open them for relations (and later trade), and simply settle nearby areas quickly, to make going further into our lands unappealing. Just opening the borders with Korea brings ETA on Math down to 27 turns. (Giving us a 2 gpt trade route at the capital.)
The capital completes its warrior in 1975BC and goes on to Settler(20). A barb warrior appears nearby the same turn, so it was a good thing that I trained a Warrior, rather than a Dog Solder.
In 1925, Border expansion at Poverty Point put Portugese culture on northern forests down to 32% from the high of 42% the previous turn, so I might leave this forest to wait for Math (currently due in 23 turns).
Next turn Portugese culture on our forest goes down to 27%, so I decide to leave the forest pre-chopped and move the worker to prechop the other one.
And on my last turn we get the "Failed Marriage" event, giving -1 relations with Portugese. This could cause problems later.
I was diligently scouting coastline, but this means that we don't have a warrior to garrison our city #3. I suggest interrupting Settler build with another warrior. This would also let our capital grow to size 5. (The current happy cap.) Another option is to recall one of the scouting warriors.
Our production is very low, and this already worries me, especially considering the fact that northern half of the continent will get very cramped soon. Perhaps we should have tried rushing Jao after all.
Also, should we sign OB with Jao? I think we have to do it to counter the penalty from bad diplomatic event.
