was to align with the three men and blindside Kim with her idol. Then take out the next strongest female, which is Chelsea.
Now they are sitting at the F7 and can re-group the female alliance to take out the 3 men in succession and get to the F4. But, hold on, they can secretly work a F3 deal with Tarzan to take out Sabrina/Kat in 5th/4th place respectively once they get to F5.
Now those two are sitting in the finals with a Goat and their strategic gameplay was so good it would have to garner some respect from the jury. They played the game as hard as possible and can say they easily outwitted the other players.
This strategy is easier said than done, but what else do they have to think about out there on the island? It's a simple math/chess strategy, not rocket science.
