Here is my solution for Scenario 2. I haven't yet read the solution and I will after writing this. I will start off with the basics I consider befoer a turn like this.
- If cashes, he is more than likely to expand into Europe, or simply beef up borders. Given you reinforce Kamchatka, Blue is unlikely to risk his new troops in attacking you.
- Given you and Yellow cash, Yellow's path of least resistance is into Europe, or possibly even South America. If Yellow cashes, then taking away Green's bonus in South America will probably be a high priority because Yellow's only border threats to Africa is Green.
-If Green cashes, there are two avenues he may travel. The first, and less threatening to us, is placing most of his bonus into Greenland. From here he can hollow out Blue, as Blue's interior is all 1's. His other option, which would be more beneficial to him and worse for us, is if he placed only a few in Greenladn to stop blue's bonus, and the rest in Western Europe. From there he could both defend against North Africa and Yellow, but he could also get his Europe bonus, given he reinforces Ukraine and South Europe.
Despite this,I would start off by cashing in my cards, making my total reinforcements 15.
I would first request a 2+ treaty with Blue at Kamchatka-Alaska, noting that he is under immense pressure from Green on two fronts, and a treaty would allow him to free up two more men to make Northwest Territories and Ontario into 2, making an attack from Greenland uinlikely, and an attack to Greenland viable. Most anyone I've played with would accept this. The scenario states that everyone seems interested in their own continent, so Blue should be more than happy to call a treaty here.
Given the treaty was enacted my reinforcements would go as follows:
- Eight would go to Afghanistan.
- Seven to Siberia.
First attack: Kamchatka - Yatusk. Eliminate any Yellow presence inside my borders.
Next whatever is left from that to Irkutsk.
Attack Ural from Siberia (and either continue on to Irkutsk or take ), leave one army there, and take Ukraine. Leave whatever remains of Siberia in Ural.
That attack will make Blue think of North America as his base, and will increase the chances he takes Green as his primary target, posibly even invading South America is he cashes.
With the 5 men in China, take one man off of India, then finish it off with Siam.
Continue on and attack the Middle East with what is left from Siam. this attack will most likely fail, so use the 11 men you have in Afghanistan. Now attack Ukraine and Southern Europe. Green will now realise you are a major power, and prefer to cash his cards in Greenland and Venezula and take on Blue for the Americas, because he will have him pincered.
Assuming you have a border treaty with Blue at Kamchatka, move any men left in your territories and spread them between Middle East, and Ukraine. Before doing this you may even want to take East Africa and leave 1 army there, so as to take away Yellow's +3. This should only be done based on what type of player Yellow is. If he is likely to retaliate to Asia, then don't do it. If he s more likely to simply take it back and concentrate more on Green i nSout hAmerica, because it is an easier target for him that someone controlling Asia and Australia then take it.
From here you are making 15 men per turn (18/3+7+2) and have a treaty with Blue at Kamchatka, so it should be easy to Force Green and Blue into each other, and you should be able to hold off Yellow.
It's late, I probably left out lot's of that. I had it going in my head but didn't write it all down.
