Call Your Bluff

Many threats are cheaper to make than to carry out, so test them before you fold.

Calling a bluff means challenging a threat or claim so the other side has to prove it. The West answered Stalin's Berlin blockade with an airlift, and he backed down without war. Carl Icahn bought into Herbalife against Bill Ackman's huge short, and the company did not collapse.

Test take-it-or-leave-it offers and assumed barriers calmly. But calling a bluff carries risk, so start small, keep an exit open, and make sure you can afford to be wrong.
