In hotseat testing I came up with a similar defense that can be used in Norway. Well, not really. The only thing it has in common with Ali's rope-a-dope is that it's passive. But I like the term rope-a-dope and thought I'd name this tactic it.
The situation was that the weather was fair across the map on turn 3 (October 11, 1939) and the axis successfully crushed Denmark and landed in Norway. Fair weather in Northern Europe means that the allies can NOT rail the Bergen and Trondheim 2-step garrisons to block the two German infantry corps. Thus, it appears that the Germans will easily conquer Norway next turn, even if the Oslo garrison is repaired to 5-steps. Well, not so fast. By moving the Oslo garrison out of Oslo and adjacent to one of the two German corps there is a 50% chance that Norway can be saved at no cost! If the next turn is non-fair weather in northern Europe (50%) then the German corps will only have a movement of 1 and the uncovered German corps can't reach the empty city. The only hope is for the adjacent German corps to knock 0 or 1 steps off and force a retreat into Oslo. Then the uncovered corps could move adjacent and advance into the city if it finishes off the Oslo defender. In the example below, the adjacent German corps inflicted 4-steps loss (double that needed to destroy the garrison) and the uncovered German corps could only move adjacent to the city. The allies in their turn will be able to rail one of the two remaining garrisons into the city. This "rope-a-dope" guaranteed at least one more turn for Norway, which means 4 extra PP's for the UK, for free!
