Many negotiators reveal their true reservation price if they trust and like the other party or desire a long-term relationship. However, we think this is ill-advised. There are many other ways to demonstrate trust and build a relationship, short of revealing your BATNA. Revealing information about a BATNA or reservation point is not a pie-expanding strategy; it is a pie-slicing strategy, and as a pie-slicing strategy it reduces a negotiator's power in a negotiation.
