This has been discussed before, but I would like to be more open about the possible alliances. The only restriction is that there should be an alliance between Russia and Germany. The alliance could either be the result of the treaty of Björkö or the result of an earlier ATL alliance, probably formed before 1900. How would the other great powers relate to such an alliance? Which powers would join a counter-alliance and which would join the russo-german alliance? What would trigger a war and what would be the outcome of the war?
