I would combine A and B. You never know how many new regiments they'll commission. I'd say try and take out the Tver (or any other) army, and then wait for muscowy and Novgorod to come to you.
For Tver army 5000 cavalry is enough. But what will AI Muscowy army do? Sieging our province, defending Tver from us, or sitting idle? Any guess?
Yeah. After converting Yaroslavl to Sunni Muslim, their were some rebellions. When we defeated rebels, they gone to Novgorod and created Sultanate.
Russian winter attrition was so annoying. If I send 15000 soldiers to Muscowy, then within 3 months half them is died of attrition.
Edited: P.S: Currently here in Mongolia snowy storm is going. Outside at least minus 25 Celsius.
P.S: Our new king is admin point's below 7. How can I get rid of him, after putting down revolt?
