@Flashman:
Technically, you are correct.
But I’m pretty sure KH will rule that no Allied power can control tt in post revolutionary Russia, just as Russia may control no tt outside its own original tts.
This small political window overrides other rules until it resolves itself.
I hope that’s the case, that it’s changed. My point here is that as it stands this is what the rules seem to be saying, and thus an actual change is necessary if USA is not to get the TT in that case.
Here’s the write-up, since I already did it, with a new question that might become mostly moot.
G6: Germany takes control of Russia, wiping the last Russian land unit off the map as well.
UK6: UK moves into Moscow from Karelia, contesting it.
O6: Ottoman Empire establishes CP control over Belarus, Sevestapol Ukraine, Livonia and Tatarstan.
R7: At the end of Russia’s turn, (they had no units to do anything, for the sake of simplicity), Moscow is contested, CP controls at least 3 adjacent to Moscow, plus they control at least one more Russian territory. Thus, the Revolution occurs.
UK7: UK forces contesting Moscow fail eliminate all Germans. UK forces are removed at the end of that turn. With no Allied units in Moscow, it becomes German.
US7: USA Attacks CP-controlled Livonia and destroys all CP units. Moscow is under German control. USA takes control of livonia, and then at the end of its turn, removes its units there.
One thing I can’t keep straight from game to game is when control is achieved. Let’s say in the same scenario above in addition of the contesting units attacking in Moscow, UK forces in Karelia attacked Livonia. When exactly does control of a territory change? After each combat? At the end of the phase?
If the UK units in Moscow are wiped out, then Moscow becomes German.
If the CP units in Livonia are wiped out, then Livonia becomes Allied.
But, depending on which on comes first, it seems that Livonia would be either British or Russian.
(EDIT: I guess this might apply to some situations outside of the Revolution)
