Imbed items or issues that are relatively unimportant to you into the negotiation and treat them as “essential.” Use these items as trade-off concessions to gain agreement on items you really do value. Asserting things that are not true or taking positions or making an offer that is ultimately withdrawn after the introduction of the issue has impacted the other side’s position. Used like the “Bluff” to test the other party. It works when you agree to forget about some of your real interests in exchange for the other party forgetting about some of their “straw issues” or fictitious interests.
