well normal bid is about 28 which is 16 extra ipc’s usually that all goes to russia. If you force it to be split, I think it’s pretty even, It might slightly favor allies, but I’m not really sure. I played this way against someone on this forum who didn’t believe me, I was germany, and won easliy (>99% odds on moscow)
what do you think about a russian sub in the white sea for a bid, it seems crazy, but someone did it to me, it was very effecitve. Iit more or less guarentees the soviet convoy, and then can be used for fodder to clean up the subs.
