Game 1 [...]
Intel is a wash: Nauz has 1/4, sanmu 2/3 but sanmu only needs to for Nauz being in Europe. If Nauz isn't in Europe, sanmu has ample time to react to a North America or Asia gamble.
About picks:
If you have the same first pick as your opponent and some similar other picks, you are probably going to get either 1st and 4th or 2nd and 3rd picks. It happens even if your opponent gets the first pick and has picked 2nd where you picked 3rd. If the 1st pick has gone to him he never gets both 1st and 2nd picks: I was quite surprised when I discovered that in that case your 3rd pick has priority on his 2nd.
If you pick both Oceania and South America on that board as first picks, you're most probably not going to get 1st and 2nd pick so you must have 1 between the 1st and the 3rd pick if not both in some cases.
When you want to pick both the 2 armies per turn bonuses, a good strategy imo can be to pick as second pick a counter of the bonus you're not picking as 1st pick and as 3rd pick the countered bonus. (This game would have been harder for sanmu even if Nauz picked 1st Oceania and 2nd Africa as they both picked Africa as 3rd.)
Noone has picked it but I'm not that sure about North America being a so terrible 4th pick, if you get both South and North America and your opponent gets Australia and Africa, you aren't in a very bad situation probably. You should be careful because your opponent can try an attack with 9 on North Africa and if you have completed South America on turn 1 and he has the first move on turn 2 you have already lost. To play safe you should complete your bonus on turn 2 If he has not attacked North Africa with 9 on turn 1 or on turn 3 If he has, saving 3 armies in the spawn in north America to get a reinforcement card piece on turn 4 if you have to play defensively.
My picks would probably have been: 1st Brazil, 2nd Africa, 3rd Oceania, 4th North America.
Returning to the played game: sanmu can't be 100% sure about his opponent being in Europe if Nauz doesn't move as he can also be in North America, which was quite tricky as 4th pick (even with Oceania as 1st) since it was risky to complete Africa very soon with a probable danger coming from Europe. This is one of the reasons why that move on turn 1 is a mistake in my opinion. The other is that it may already give to your opponent an intel about the move order, but in the game the fact that sanmu has not attacked North Africa as first move avoided it (Nauz should instead know from turn 1 that he moves first on even turns and as second in odd turns since the 4th attack by sanmu arrived after his 4th attack). If I was in that situation I would have attacked South Europe (to take Western Europe is a mistake imo since you do not have a double border with Africa and you are wasting armies that your opponent should use for that neutral) taking it with 11 armies on turn 2: samnu is probably going to enter Europe to block it or he is going to try to complete Africa, in both cases an attack there on first move is quite dangerous for him.
Verdict: Decided on picks. After picks, it was sanmu's game to lose.
I do not completely agree with that. Returning again to the actually played, I think that another main mistake from Nauz has been the fact that he has tried to attack North America from Asia while Europe was probably far better for that purpose. In his position I would try to take Greenland very soon and use the 6 australian armies to get Middle East trying to put further pressure on Africa if sanmu tries to get it. If he manages to block North America and Africa it is still a 7v7 game, hard to play but not impossible to win. In the moment North America was completed and safe, the game was over of course.
