The Washington Post today:
Diplomatic Efforts Unable to Derail Palestinians' UN Gambit
"Gambit" is the kind of word that seems intended to send a certain message–as if there some kind of sneaky maneuver at work here. That's especially true when it is contrasted with "diplomatic efforts."
In this case, the paper is referring to efforts by superpowers (like the United States) to tell people with very little power (Palestinians) to pipe down. Whatever you think of Palestinian efforts to elevate their status at the United Nations, an alternate headline–"U.S. Gambits Unlikely to Derail Palestinians' Diplomatic Efforts"–is hard to imagine.
