As I’m pretty sure we all know, every negotiation that we engage in is  all about information. 

What do we know, what don’t we know. For that  matter, what does the other side know and what don’t they know? We all do our homework before the negotiation starts so that we’ll have as much information as possible. However, there is always the question of how much we should reveal to the other side during the negotiation. Just exactly how close to the chest should we be playing our cards? 

What should we reveal and what should we keep private?
