LAST EDITED ON 08-05-11 AT 12:08 PM (EST)Big Brother isn't really about strategy anyway if, by strategy, you mean making moves like in chess. For proof, Shelley and Jordan are in very good positions while doing basically nothing more than being nice and non-threatening.
Agreed, not like chess, partly because there's no element of diplomacy in chess. But have you ever played the board game Diplomacy? In that game you try to set up alliances, break up others' alliances, enter into non-aggression pacts, make neutrality declarations, temporary arrangements (team up for a week to accomplish a shared turn objective with no long-term commitments) and so on, with the battles being more a resolution of diplomacy than military tactics. It's very much a strategy game and I see a lot of parallels between the two. If you haven't played Diplomacy, another game that is sort of close along these lines is Risk
There are also some computer-based diplomacy simulation games that go along these same lines. There is some game theory that applies to this in optimizing your chances of winning. You could theoretically set up a turn-based computer game for BB and try out the various diplomacy strategies and responses. Indeed, it'd be fairly easy to set up a simulated BB game on these boards (and I might try setting this up and host it!).
I guess my original comment is that ED has played, watched, studied and commented enough on the game to have a fairly good grasp of the diplomatic strategies, particularly the timing of when to create/shift/break alliances and who to do them with.
(eta) Just for the fun ot it... I've opened up the Hamster House game in Fanatics!
