In any case, you fight defensively, so why bother with the Trade Dispute when you can call your allies into a war for newly vassalised Tver. The allies are non-numerous, but every bit is precious![]()
The trade dispute war is an easily winnable war that is intended for the following
1. Wear Muscovy and vassals's down, via Manpower and WE
2. Gain time for increasing relations with Poland and Kazan.
3. Gain time for Poland to gain Lithuania union. Poland will probably only rival Muscovy when they have Lithuania as a union.
4. Take the initiative on when to start the war. If you choose to DoW Tver first, there's also a probability that Muscovy will DoW Novgorod while the NOV-TVR war is ongoing. And this will scupper the start. Only ally you can get at game's start is Ryazan.
I actually enjoyed Arumba's video for giving me the idea of doing the trade dispute war, and further how to fight effectively in the Luki- Novgorod pocket. He didn't really execute it very well but the idea was correct.
