I want to block Muscovy from Siberia and I can do it very, very early (~1495-1500). The main concern is that I'd have to wait for the annexation my vassal, Nogai, who's basically in my way to Siberia.
The plan is: attack Kazan. Make them return all Nogai provinces, and take one in the north for myself. Send a colonist there ASAP. Once the first colony is done, send the colonist to the second province in the North - voila! Muscovy blocked from Siberia.
But this strategy relies on being able to colonize next to non-cored landlocked provinces.
(Ironman so no second tries
)
