Hey, it's that eB1252 guy from reddit! Thank you for trying my strategy (more of a cheese actually). I forgot to mention some stuff though.
--- Because you have so many divisions, and no air superiority, pushing the Germans back is a pain in the arse. But, because the Germans don't defend Königsberg properly, you should be able to push them. Then, when the Allies begin Normandy landings, I recommend you to land a naval invasion in Northern Germany, which will catch them off guard, they will take some troops to your naval invasion. If you bring your tank divisions (preferably 14medium/7motorized), you can even take Berlin, which will make things a whole lot more easier.
Have fun mate!
