RNG strat, Conquer & humillate Korea + dismantle fortifications on China to become GP, Exile soldiers near Russian capital, Become Scandinavia (Optional before the war, on 1 practice attemp I beated like on August of 1845 so its possible), Wait to Russia Sphere Krakow, wait Russia to add 1 wargoal against you, build enough battleships to not let Russian Army pass to Stockholm, attack on St. Petesburg and wait to win by battles or wargoals.

The RNG part are how fast you can officially become GP, how fast Russia can sphere Krakow & how fast can Austria abandon them.

Ally with Prussia & The Ottomans wasn't part of my original plan, it still worked tho.
