Well, this leads to all sorts of scenarios.
During the Reagan administration, the US would buy up blood supplies all over the world to see how the Soviets would react, and to start a war but be blameless. I think that Caesar came up with that concept first, to draw your enemies into a war, knowing that they might be ill equipped to fight it. You might add in a False Flag operation to get things heated. Leading up to the American Revolutionary War, the Boston Massacre was an attempt to draw young British troops to fire upon unarmed Colonists at the Custom's House where amongst the crowds there were paid agitators who got the crowds all stirred up and incited them to willing to take unnecessary risks themselves, so that the propaganda machine could rival up attitudes against the British.
Similarly, there are trading strategies like this, mostly in the form of pump and dump. You put in a massive buy order, hoping that that information gets out there and gets others to follow suit. Just before trading begins, you cancel your requests and sell into the roaring open. Sort of a gambit move.
In fighting, there are various tells, but you can gain ground by displaying false tells, baiting your enemy with misdirection! Knowing that others are looking for those signals, you can try to force their hand!
