What won in 2006?

[Grim Tuesday]

We are doing training sessions for new members, and in that, we want to teach them about strategy. The way we're doing that, is by going through a few years of games, having them brainstorm strategies, present them, 'decide' on them, and then play a practice game with people as robots, then, finally, reveal what won that year.

I want to do 2006, because it is such a strategy intensive year, but, considering I wasn't around (around FIRST, that is), I need some help. Would someone around here be so kind as to enlighten me on that front? Thanks in advance.
