I know there is already a thread here, but it doesn't help me.

I think it's clear to get the orange circle within 2 turns. Then I tried to concentrate on the south and just put a minimum to the north to distract the AI. I leave the path in the middle to the AI.
At turn 6 I get into contact with the AI and that's the point where I don't have enough armies to defend 4 places against armies with more ressources. Even if I manage to invade the blue circle, he will then have destroyed all my defences and I'm totally open. It seems that the AI doesn't go in this level with the rule just attack with minimum - he has too many armies and uses all of them.

It would be helpfull if somebody could tell me how many armies they use for defending the orange circle and how many per line on the attack in the south.

Going north and breaking into the center is what worked for me. The center is key since the income is so much higher than north or south.

If the AI attacks you with a lot its because it has more armies then needed. If you got a stack in the north the AI will use its armies either to defend or attack that stack. So it will not use more than the minimum attacking you in the south. I used decoys in the north that I moved around and kept AI bonuses broken. While I took the south by using a minimum of armies. When I broke his circle I almost had all the south.
Most areas has at least 3 areas that leads up to them. If you got 10 armies the AI needs 3x16 or 2x16 + 7 or 16 + 2x7 or 16 + 0, depending on how many armies it got to place. Thats how you make sure that the AI uses the minimum in the south.

How many armies are you using initially in the north? For the first attack to place the decoy?
Sometimes the AI comes in the south with 20+ armies at the first contact and sometimes also in the north and then goodbye to my decoy as I can't hold both sides if he is coming on one side with that many armies I need all my income to hold that side while I try not to break on the other side. I don't manage to advance. Would be good to see a video of somebody to have an idea. You can't copy in any case as the AI doesn't react always the same here.

You dont have to hold the line in the north. Thats the point of this strategy. You have a big stack and keeps the AI using armies in the north.
In the south you do attack with minimum armies. let me give an example: you have 4 armies in an area with 2 areas next to it. you put in 10 armies (4 + 10 = 14) as you know the AI will hit it with 2 * 6. you will lose 8 armies. that leaves you with 6. Dont attack with the 6 but only 1 in each area and move the remaining armies backwards. that way you only have to defend 1 army in each area next round. And if the AI does not attack that area but only do defence you will have 0 armies in the area to defend next round.
Another thing is that you should always attack after the AI in the south. Make sure to make enough moves with your left behind troops that this is the case.
To answer your question about how many troops I had in the north it was 66 when i first met AI.

In the north I just hold my at my circle.

In the south I grab the bonus' until I meet the AI. This meeting happens right where it bottle necks down. I send my main army the the center to get the bonus' there, and smaller army to break the AI bonus'. I've been able to get to the point where I get 29 armies a turn and the AI gets 21.

But then, on turn 12, the AI plays a reinforcement card which gives him an extra 40 armies! The AI must start with 80/100 pieces already.

Then, on turn 16, he plays a sanctions card.

I'm fine with the AI starting with his circle bonus at the beginning give him a 9/19 advantage. I'm fine with him starting with 39 armies and I only starting with 15. But how am I supposed to fight back against the AI getting a turn with, essentially, triple armies?

I can try this again tomorrow, its late for me right now, so I'm sticking it at one test run.

Passiveness at the north is a bad idea. The AI isn't particularly strategic, try putting a bit more oomph into those northern decoys. Try to get it to overdeploy to eliminate a stacks you run around inside whichever north/south area you chose, so you can defend/conquer the other areas.

Prediction should help here. You know he has extra armies coming at you. It sounds like you are able to break past his initial onslaught if you can get to 29 vs 21 income. Stacking your own waves and blocking his attacks with your stacks + defender's advantage helps a lot. Its not like you have to really guess where the stacks go either. That first turn where you meet is huge, since you can gain a large advantage that can temporarily override his income. I'm guessing you already do something like this though. I nearly made it despite wasting a couple of turns blocking a stack that never came down the middle.

For your turn 12, I would suggest making the battlefield as chaotic as possible. Give the AI a lot of places to attack, and you'll have a better chance of riding it out. If the AI only has to push at one or two spots with income advantage, he'll just break through. But if you are able to convince it to deploy in many spots, you can "ninja" some of those with similar deployments, making the attacks bounce. In other words, I would consider turns 8ish - 15 as playing around that card. Its physically impossible to do that in one turn, you're not crazy.

Side note: Playing around expected opponent income advantages and positional weaknesses - these are important skills to start picking up if you ever start trying multiplayer. A bit more advanced than you'd like for a newbie, but still useful to be aware of.

Thanks, I Swear.

I tried kss31's method and it finally worked.

I launched a big attack up north and only kept the minimum down south. The northern campaign had about 65 when I met the enemy and I just kept it marching toward the enemy circle. If you keep a big army moving in a direction the AI will chase you, adding a few armies each turn. Eventually you'll notice that you're dragging a very large enemy army behind you. They retake any territory that you capture in two turns but they can't use the armies they're chasing you with for anything else. By the time I got to the enemy circle my army has been knocked down to about 20, but the enemy army behind me was over 100.

The southern campaign is essentially an exercise in cheesing the AI. The key to kss31 strategy is to always withdraw your armies away from contact with the enemy at the end of each turn. This way the AI loses track of your armies and only sees empty territories. Since it can see a big army up north, it deploys most of its new armies up there and only just enough to capture the empty territories in the south. Then when you make your deployments you just need to deploy enough to counter the small attack the AI will make and a couple more to make a small counterattack after defending. The AI will lose all its armies in its attack and you will gain territory with your counterattack. This will allow you to slowly gain territories in the south, and since you're constantly retreating the excess armies, you're building a fairly large army just behind the lines down there to eventually deal with the large army chasing the northern group.

The AI getting to use a reinforcement and sanctions card early means I still had to hurry and ensured that I absolutely had to use this strategy.

Kudos to the map creator for making a map that demonstrated an AI exploit. And I guess the fact that I learned something is good, but I would have rather had a hint that I had to exploit the AI, because I tried this map, like, dozens of times before I started searching the forums.

I still don't really manage. This map would be a good example for a video tuturial. As the AI reacts always differently (at least for me), you can't copy it, but you can learn by watching.
