I agree and disagree on Sz 37. Lol!
I think it is bad if your thought process is “I can try to kill these J units” (cause they are right there and it is so tempting!) but after that you don’t really have a plan.
However, it is very powerful if your intended strategy is to go after Japan with the US. (quick note, I wouldn’t do sz 37 without at least 1 bid unit).
With coordinated US 1 moves you can have a US fleet at Wake or Sol in rd 1 and from then then on you pick off 1 island a turn while keeping your fleet out of any danger.
This assumes you will be committing 100% of the US to the Pacific.
That said, I have a much harder time in the Atlantic going KGF, then I do going after Japan. So it could just be a byproduct of my play style right now. I’m good with Russia and good at going after Japan, but the Atlantic sea zones still bother me for shucking purposes. I’m just not efficient there yet.
Africa in rd2/3 seems about right, then heading north as MI suggests for rd 4 seems like my normal Atlantic time frame. But beyond that I start to lose efficiency in the Atlantic some where along the way and it turns into desperate mode of keeping Rus alive instead of doing something productive and eventually J just gets too strong. Whether it is rd 10, 15, 20, etc, the writing tends to be on the wall for a while.
