Hmm I do know the reason Daniele played the sad card is because she was pretending her dad was not taking her off the block. I dunno, but I think the chess pieces could just be like that since it is this years theme. I am almost positive that it would be unfair to the other HGs if they didn't even know they were looking for something. So I doubt that that has ANY truth whatsoever. Just my opinon, then again I don't go to other boards, and what not.
Its never set in stone who is going home (even with Carol/Amber there were back and forths of the MRA possibly evicting Amber and not Carol). But Zach said the ONLY way he would vote for Dick to stay is if Jess came to him and "relieved" him of his vote. And Jess and him were just talking today about how he was still voting out Dick for her. And she appreciated it. So no Zach is not going to change his mind. He wants Jessica, is that not obvious? Jess has him wrapped around her little finger because her of her body. Yet she hates him lol.
The only time I have heard mention of the coup thing is when Dick and Daniele were asking when it would happen. But again, they would have to give all HGs clues so I seriously doubt it is under the chess piece. They just WANT it to happen so they can change the noms. And I would THINK they would have to do this by tomorrow so the people they put up can pack. I dunno. I could always be wrong.
