Tonight is not a game of easy decisions...!
If we win against the US, we are not guaranteed the first place on the group, we will need to win against Brasil as well because of our lower PD (the US play Ecuador next week, which should give them around +40, and I don't think we can win by more than a few points). And Brasil will have a say in this because they will fight for the 2nd or 3rd spot in the group. On the bright side we'll have a guaranteed 3rd spot at least (and Worlds repechage next season).
If we lose against the US, we could very well end up 4th if we lose against Brasil as well next week, which would put us out of the Worlds repechage. Also it depends on tonight's Brasil-Uruguay game result, Uruguay needs to win to stay alive.
Saving enth tonight could help us win against Brasil next week and give us the 2nd spot, which means a semi against Argentina@home, that one will be hard to win.
Trying to get first place of the group could give us an easier semi (although Chile and Peru are really strong), which means a direct qualification to the Worlds (both finalists gets to the Worlds directly).
In other words, the game is in 3 hours, the lineup is set, but I still don't know what to do. From the beginning of the second stage this game was a sure loss and an opportunity to boost our enth levels, but now that we have a shot at the 1st place I'm not so sure anymore...
