Quick thoughts: This turn was all about failures to understand what Russia's motives are, and England and Austria paid the price.
So what was Russia's interest? He had a slow start, but there was real opportunity in the north. Further, he needs to get established in the north before Germany falls for real because he needs to be a viable ally for France who can hold back England. If England can just roll him in the north, he is careening toward an E/F/(A or T) draw. Similarly, Turkey falling quickly just means he would have to hope that he isn't next (and Austria just built two armies!). What this means is that he needs time to get himself established. Germany or Turkey falling (yet) are not good for him.
So what should England have done? First and foremost, don't help Russia and Germany untangle! That's the worst move of the turn. Russia and Germany were badly out of position to work together, and now they are in great position to work together. That's a disaster. You needed to push him in that direction- point out that between you and France you will be cutting Kiel and Munich next turn so Berlin is guaranteed if he moves Livonia that way as well. At least don't let Germany into Denmark. Never allow other players to establish clean boundaries.
How about Austria? One of the most important things that happens in 1901 is whether Russia takes Rumania with a fleet or with an army. Basically, if Russia takes Rumania with a fleet, Austria is safe, and if he takes it with an army, the juggernaut is on. When I play as Austria, it is my number one priority to get a fleet in Rumania, and I'll do extreme things to get it. For example, in
gameID=164615 I promised to build a fleet in Trieste for my first builds if Russia went fleet Rumania. Here, there is army Rumania, so that's a big red flag. There's simply no reason to expect Russia to work with you here, and you don't need him to anyway. There's very little reason to go for Bulgaria here- the slow part of the Lepanto is the fleets. It would have been much much better to go to Aegean Greece and Serbia. Also, if you are going to do the moves you did, at least just move Trieste to Serbia and do something else with Budapest. It's insane to move your pieces in some absurd chain that can be bounced at any point.
Finally, sort of similar to the England thing- Germany, you have to have to have to pop the French army in Ruhr there. France is all in against you right now; he only has one fleet. Your need to create a clean border with France and give him the opportunity to switch course. You are unlikely to lose Holland if you do so, and even if you do, who cares that's fine you are further unbalancing the E/F.
