Second Part.

Look at the map of the Frontiers from Wiki.

The French 5th army was vulnerable to encirclement twice IOTL. Here there flank is hanging even more in the open. The French probably lose this army, but even if saved it will mean a significant retreat. The Germans will stall due to supplies. We can talk a lot about the details, but we basically see the lines likely stabilizing near the Marne with the French down an army compared to OTL.
The UK will then be forced to land. If direct land on the German coast, it will be suicide. And looking at OTL, the UK avoid landing in fortified areas. So we see the UK landing somewhere in Jutland where it will be stalled by German and probably Danish forces. Then we see all the lines stall. The Germans likely do the Race to the Sea except there will be nothing to oppose them. It really will be the March to the Sea. Calais is in German hands, and this is huge.
Now nothing here fixes the A-H performance. We can debate if Italy enters the war, but lets have them enter on time for simplicity. The land war will be non-decisive in the French and Russian theaters since the Russians have too much depth to lose fast and the French get a breather since Germany has to deal with Russia in 1915. But the BEF is an anchor on the RN. Losses will keep piling up until the Germans control the near coast. Then the BEF will be cutoff and will die. The UK loses two plus armies here.
So we likely roll into 1916. The eastern front is stable for the Germans. Germany has not done any USW since it is too busy attacking RN ships withing 150 miles of the coast. In the West, we see the Entente short 3 plus armies. Lot of flexibility writing an ATL since we have had a lot of butterflies, but this year will be the decisive win for the CP. Take this as a midpoint outcome. It could be faster with things like a French panic, could be slower if butterflies cause additional CP mistakes or avoids Entente mistakes. Something like Russian 1st or 2nd Army escaping due to butterflies is not unreasonable.
On side note, this is huge Ottoman buff. With the open amphibious fronts in Jutland and desperate need for additional Entente troops to save Paris or save Calais, Gallipoli is unlikely to happen. The Australian national identity is forge in some other fierce battles. The Ottomans still make mistakes, but give the lack of pressure, the Ottoman have enough troops and time to recover.
On second side note, if Italy does not enter the war, the war could in 1915 or very early 1916 with CP victory. The offensive against the Russians in the East does not stop until force by snow. If the CP lines are 150ish miles to the east and most of the Austrian forces facing Italy are in the East, then the strategic situation for the Entente is even worse. Also, with more troops, Serbia will fall faster. Bulgaria will likely enter the war sooner. Ottoman supply situation will improve a bunch. Italy will make a fortune selling war materials to CP. All that ammo shot against Italy is usable on other fronts.
