We should trade for AH first, because if we find horses somewhere we might need to change our worker action plan. I still didn't move the workers on my last turn.
If we have no horses we can use the worker sequence from my plan since I have everything calculated up to 1000BC, but it might still need some adjustments. Note that worker #1 was sent to the tile 1S of Athens, not 2S, because as Dynamic said, river corners don't give the extra coin for the FPs. This should also lead to several minor changes in the following 10 turns. Then I am also not sure what to build in Sparta & Corinth. More workers, I guess, but its not certain.
