In OOB I like the idea of going for a Yunnan stack with the help of russian air. The reason is that there are no drawbacks to a DOW, as opposed to BM3.

It’s possible to tweak this, like adding another inf to China or art to Siberia. I like however to boost the british navy, although Taranto might not be advisable. Taking out Ethiopia is usually sufficient to secure Cairo, especially with the other boosts.
Main idea is to RDOW1 (against J of course) and send in 3 fig, 1 tac to Yunnan immediately. This makes an attack there suicide. Not being able to contest Yunnan during J1 dissuades a JDOW1, but J instead needs to either focus on contesting China or circumvent it all together.
China will earn 6 extra IPC longer and also gets the option to build art. That’s heavy. This will have heavy consequences for J’s income for a long time and makes US prescence in the Pac more feasible.
Simply put, this strategy will help to take out J earlier, making US-investments in the Atlantic rational earlier.
