I know that people have talked about this as being unlikely, but in our second game Russia voluntarily didn’t attack a German force in Belarus in order to trigger the revolution at the end of its turn on Turn 5. Belarus, Livonia and Tatarstan were occupied (the first two by Germans, the last by a massive Ottoman force). Ukraine was contested but Russia would win, sooner or later. Germany also held Poland outright. However, the Ottoman force had come up through Romania (Ottomans controlled that and Sevastopol), and the Russians had sent a force into Mesopotamia (Russian-controlled), Syrian Desert (Russian-controlled) and Ankara (contested).
At the end of the Russian turn, the criteria were met: 3 territories adjacent to Moscow were CP-controlled (Livonia, Belarus, Tatarstan), Moscow was in Russian hands and 1 other province (2, actually) were controlled by the CPs (Sevastopol and Poland). Ukraine was contested, Ankara was contested.
So what happens? The way I read the rules, this is what happens:
1. Moscow, Kazakhstan, Karelia and Finland become impassable for the rest of the game (goodbye British land route from India through conquered Afghanistan)
2. Mesopotamia and Syrian Desert are also impassable because they were Russian-controlled
3. The forces in Ankara are removed from the game.
4. The forces in Ukraine remain and essentially, CP forces can move through but cannot get money from Ukraine or fight Ukraine (though they could fight Allied Powers in Ukraine).
However, for some reason one infantry needs to remain in Ukraine from the CPs (what happens if Allied units want to attack it?)
5. Because Moscow is in revolution the CPs will not be able to count it toward their victory conditions
Is this right? If it is, then the CPs were right to essentially assume that they were finished (Austria had nothing left and Italy was going to probably take Vienna that same turn, Germany had troops but the British and French were in Alsace and Belgium and about to invade the Ruhr, and a massive American force was making its way across the Atlantic; the Ottomans had sent so many troops up into Russia that the British were in Smyrna and, with Italian help, were probably going to take Constantinople).
