Sorry for my absence, I've been a bit ill lately
Good move shyuhe - somehow, something like this was to be expected
That land to the east - omg. Culture might be so easy if it weren't for the other things we need to achieve. I found this point by LTC good about opics not being the optimal path for cultural victory... We need to think about that. If we want culture, and with the capital chopping 1-2 wonders (oracle and mids or so), that 2fish pig cow city and one with 7 FPs and 9 riverside tiles total, this might very well be a good option - we don't need THAT much teching if we take that route - we can take astro off lib to settle cities overseas, maybe we'll want rifling/steel to aquire the last resources, but that's it. A reason not to go culture is that we have yet to find stone/marble. Another is that it's not so easy to control it if we need more time to get the resources or (unlikely) another GP...
Zara being so close usually would mean we'd rush him but not here I'm afraid

I am impressed by all the info you're reading from the game, LTC
I'm not feeling too much rex pressure though as this is only emperor level and zara is so close. IMO we can block him off with 1-2 cities + capital maybe. Let's see what the Mighty Map Creators gave us...
We'll surely want to be at pop3 when starting on the settler to work the two corns and the silver plains hill. I'd say we build 2 warriors, not sure how far we'll be pop-wise but we'll be growing so fast that we're at the very least pop3 when the 2 warriors are done. The first of the two can go directly east, along the coast and move up north while the second can go directly north. Our existing warrior can move further north if possible (NW first).
I'm not sure about what to tech. BW means we'll see copper AND can chop forests AND could start whipping... Not sure it's worth to delay it for the wheel. OTOH with silver we can race through those early techs so fast that it doesn't really matter whether we tech TW > BW or vice versa once we get our first settler done but the worker could start roading (or chopping) earlier. I think I might just prefer to go TW first to give our worker something to do earlier.
Definitely improve the two corns before the silver.
edit:
Looking at the culture progress diagram makes it look like chokos moved their settler for several turns
