I think we all saw the sample game and thought "Wow, people weren't aggressive enough to go for box 10", then stopped and thought "wait a minute, everyone else is going to think that and put everything in 10", and then thought, "no, they're all going to think that, and go for box 9 again".
Anyway, I'm now realizing that it makes a lot more sense to just go all in on 10 rather than try to go for 11 points like I did. I was thinking someone's probably going to get 10, so I need 11 points to beat that. So I could go for 9 and 2 or 10 and 1. But 10 and 1 doesn't make sense, because if someone's going to get 10 points, it's going to be from the 10 box, and either it's me and I don't need the extra point to win, or else it's not and I'm losing anyway. I could have looked really awesome going for 9 and 2 except that Watno screwed over anyone going for the 2 box anyway...I'm not sure I get that, since the goal of the game is to maximize your chances of scoring more points than everyone else, not to score as many points as possible.
