I worry about making earliest settling of All the Marbles our top priority, because it will not be all that strong a city until we can pop its borders and also clear the seas for seafood. And I am not sure marble will actually help us in time for the Oracle, assuming we go for the Oracle rather than a stack of military.
To get marble for the Oracle we need: finish AH -> Mining -> BW -> Mysticism -> Masonry -> Medi/Poly (one of) -> Priesthood
How long is it going to take to get all those techs? Can we realistically get them all in time to finish the Oracle before an AI does so? Even to build the Oracle in our capital without marble we need everything in the list except Masonry...so maybe Masonry moves to the end of the list in case we can't get it in time?
Has anyone tested to see when the AIs might finish the Oracle? To build it in time I think we need more commerce to speed research, so getting the capital larger sooner so it can work the silver might be important.
dV, I like some of your dotmap (marble city, yellow dot) but I am not sure about your pink dot. What would this do to placement of a city to work the wheat? And also for a city to work the deer? I had been thinking about the burned city location, grabbing the fish in addition to one elephant and the wheat. But maybe further south would be better, maybe 1S of the fort to grab both elephants and the wheat? Then we could leave your pink dot site until later, once the triremes have been dealt with? Pink dot would not have anything but seafood, so it would have to wait.
Or...hmmm. Maybe SE of that? Grabs wheat, both elephants, gems, and banana. Lots of jungle of course, and we would probably lose the banana to Suleiman's culture.

Not sure.
Maybe we really would be better off building a stack of axemen? The best city sites available are probably Moscow, Moscow, and Istanbul.

That assumes we have any metal to work with for axes...or horses. It is tempting to grow the capital working the cows, and play at least three turns so we can learn if there are horses available. That would discard any settler at size 1 plans, but I am not sure I like those plans anyway.
