Well, the German is not going to get the Russian BBs unless they could occupy as much Russian lands as OTL. Occupying Poland alone is not enough, and the war is too short to occupy as much territories as IOTL.
Also, depending on the situation, the French could end up not employing Joffre's idiotic offensive strategy (too risky without British backing) and instead choose Victor Michel's one and hence manage to stonewall German troops in Belgian borders. And if the German could not set a boot on French lands, their industrial base would be safe. Remember that until 1916, defenders (if they actually employ defensive strategy) always had the advantage thanks to machine guns, and the Germans could end up like the French during Nivelle Offensive IOTL.
The French are likely to get massacred thanks to them launching their offensive before Britain entered the war. Assuming the Germans still invade Belgium, the lack of a BEF at the very least leaves German forces in control of more of France than OTL, and the Schlieffen Plan might actually succeed thanks to less troops able to block German advances.
