As to my thoughts:
I don’t really like the idea of an Austria/Turkey alliance. There’s no excuse for Austria to build fleets, and without fleets it is impossible to get to 18 centers. You can’t crack Turkey without some fleets, and there was no way for me to get enough fleets to break out in to the Med. On the other hand, there’s no way he could get enough armies to crack me, though he would have a better shot. Unfortunately with open press you only get one shot at making an alliance. I tried to go with Russia and got rejected. Luckily Italy went NMR which allowed me to get some breathing room.
After that I pretty much needed to take whatever was given to me. I was pleased with the speed that I was able to expand into Russia and Germany, but unfortunately it just wasn’t fast enough.
Russia: Really screwed up by not fighting off England up north. With an English/French alliance, it isn’t a matter of if England would attack. It was a matter of when. If he had worked with Germany, even independently of me, he would have taken Nor and had a solid stable north. Allying with Turkey when he is in the Black Sea is questionable, but getting tricked by England was inexcusable. A seemingly half hearted commitment to the Turkish alliance finished him off.
Germany: Pretty much never had a fighting chance after France built all armies. Did an admirable job of holding off England/France, but never got cooperation from an ally and never really had a chance. A smart move to Bal sealed the game as a draw.
England: Everything worked out well for him. However, he never really helped his ally expand, and thus was beaten to the stalemate lines by the opposing alliance.
France: Totally blew it by building a 5th army. Gave him no chance of turning on England and no chance of defending himself when England turned on him.
Italy: Attempting to attack an Austria that is expecting it wasn’t the wisest thing. Put him completely out of position to attack anyone else. With France building no fleets, England going east, and Austria tied up east the best move would have been to go neutral/ally with Austria and attack France.
Turkey: Not quite sure what the intention was here after an initial stab against Russia. I think Russia makes the most sense as a Turkish ally, but it is odd to stab someone and then try to ally with them. Once he attacked Russia the only thing to do was drive the attack on home. In order to win Turkey needs to expand on the land. By allying with me and giving me Sev, he was in no position to do so without telegraphing a stab. Also came up with one of the more bizarre proposals I’ve seen in claiming Vienna as spoils. I have no idea where that came from or why he did it because it didn’t end up helping him.
