I made a typo. Updated below:
Player A occupies Tyrolia, Vienna, Budapest, Galicia, and Rumania.
Player B occupies Munich, Bohemia, Silesia, Warsaw, Ukraine, and Sevastopol.
If Player B enters as moves:
Munich support holds Bohemia
Bohemia moves to Vienna
Silesia moves to Galicia
Warsaw supports move to Galicia from Silesia
Then no matter what, given these moves, Player A cannot use Galicia to cut Ukraine's ability to support Sevastopol? Am I correct? In other words, this is a perfect stalemate?
