Round 6
Round Recap
I have a blue card set available this round, including E.Africa and Irkutsk.
Green is vulnerable to elimination.
Yellow and
Teal are loaded heavily in that direction with the potential to fire off card sets in two rounds.
Blue has taken S.America and threatens to push into Africa if allowed to grow.
Deployment
The possibility exists to use my cards to eliminate Green this round then use the second set of cards to push back Blue. I can't see many options that lead to the win if the attempt fails however. Using my cards to break Blue's hold on S.America relieves tension on that border and gives me the potential to hold Africa. I use my cards to deploy 11 units on N.Africa, taking Brazil. As Yellow and Green would be hard pressed to eliminate Teal this round, I take Congo as well. With Brazil and Africa in my control I consider defensive possibilities.
Blue may have a card set ready to deploy. If that's the case I would be hard pressed to hold Africa from a 13 unit assault (turn+cards, 3+10). Blue seems to find comfort in defending with a large number of troops on a border when considering past rounds. Given 13 units it seems probable that Blue will either re-take S.America and reinforce, as re-taking then breaking my hold on Africa will leave their units spread thin barring outstanding rolls. The other likely scenario would be for Blue to deploy on W.Europe, taking advantage of the 3 units already there, then moving through N.Africa to Brazil. Worst case the units:turn remains equal between us and without holding a continent a larger defending force may be prepared. This considers one ignores Pink with 5 cards sitting on Blue's back end however.
With Pink to consider, a display of force on the border at N.Africa should be sufficient to keep Blue at bay. If I can remove the temptation from the units on W.Europe as well the odds of holding Africa in any situation is high. I attack W.Europe to remove temptation.
*The 2 Units on Brazil: I have reinforced Brazil to defend with 2 units. The main reason is the probability of winning in 3v1 dice situations. Considering Taflin's "
The Probability Distribution of Risk Battles" the probability of Blue winning the dice roll in a 3v1 situation is roughly 65%. If I leave 2 units on Brazil Blue's likelihood of retaking the territory without any losses drops to about 37%. Throughout the match I've taken great effort to try and minimize situations where an opponent may take units from me in a 3v1 situation. I try to ensure at least an equal loss of units in exchange for my units eliminated. Leaving 2 units in Brazil supports this aim. As the extra unit will be put to the purpose of eliminating Blue units anyhow I move one up from N.Africa.
*A
secondary reason for 2 units is psychological. It is human nature to note failures more readily than success. Hence 100s of comments about terrible rolls of the dice for every 1 on decimating an opponent from the weaker position. I want Blue to lose a unit or two in the process of retaking Brazil. I want Blue to have that thought fresh in their mind when considering whether to continue the attack on N.Africa. I want anyone in the match to lose a unit or two every time I'm attacked. I want everyone in the game to think of that whenever evaluating an attack on say S.Europe vs. Greens 1 unit on Afghanistan.
Green will most likely use their cards to solidify Australia. Blue can retake S.America, but unless they have a RGB card set shouldn't be able to break my hold on Africa. Yellow seems to be aiming to eliminate Teal or Green to gain strength through cards and Australia. Teal is in a tough spot, might want to consider moving west and trying to rebuild units. Pink has nowhere to go but into Blue with their cards, will likely try and take N.America.
I'm in position to eliminate opponents.
