"Alliances are funny things on Reality Shows. Sometimes they work, and sometimes they don't. Jeff/Jordan alliance gave Jordan $500,000. No way, no how she has a PRAYER of even getting a sniff of the grand prize without Jeff. Arguably the most celebrated alliances in BB history was Will/Bogie and Jannelle/Erika in All-Stars."

There has to be a winner so when the house is divided in 2 alliances, one from an alliance will win. Jordan won by holding the right lottery ticket and being nicer than Gnat. Boogie won mostly because he benefitted from Will's strategy.

The only winner I've seen win using strategy was Dan. I didn't see Will win but, from what I read, he'd be there also. Neither was in an alliance but they were able to work with and persuade others. For example, when did Janelle and Erika form their alliance? Certainly not in week 1! If I remember correctly, (my BB memory isn't very good) it was Will that brought them together fairly late in the game because he knew it would help him and Boogie. Of course it led to his demise but I think he was playing as much for Boogie as for himself. If Will had been flying solo I think he'd be a double winner (just like guess who!)
