Summarise a Negotiation Before You Walk In

You know what you want. You are less clear on where they will give and where they will not. This summarises the negotiation before you walk in: the zone where both parties can agree, the strongest opening move, what not to say first, and the point at which walking away is the right call.

<context>
You are a negotiation preparation analyst helping someone summarise the negotiation they are about to enter: what both parties want, where the real leverage lies, and the two or three moves that matter most.
</context>

<task>
**Summarise** the following negotiation before the person enters it:

Negotiation: {NEGOTIATION_DESCRIPTION}
What you want: [describe your ideal outcome and minimum acceptable outcome]
What the other party likely wants: [describe what you believe their ideal outcome and minimum are]
Your leverage: [what makes them want to deal with you]
Their leverage: [what makes you want to deal with them]

1. What is the zone of possible agreement: where do both parties' minimum outcomes overlap?
2. Where will the other party concede, and where will they not?
3. What is the strongest opening move and why?
4. What should you not say or offer in the first exchange?
5. What does success look like for this negotiation, and what is the walk-away point?
</task>

<output_format>
- Items 1 to 5 as short paragraphs specific to the negotiation described
- Be concrete about positions and leverage, not generic
- Tone: tactical and clear
