The Picard Maneuver is a battle tactic invented by Starfleet Captain Jean-Luc Picard. In 2355, Picard was in command of the USS Stargazer when it was attacked by an unknown alien vessel, later determined to be of Ferengi origin.
During the engagement, the Battle of Maxia, the Stargazer, which was holding station several million kilometers away from its adversary, suddenly accelerated to warp 9 directly towards the Ferengi ship. Because the enemy was only equipped with light speed sensors, they had no way of knowing that the Stargazer had moved until it was too late. When the light from the newly-moved ship reached the Ferengi ship's sensors, the light from its previous position was still arriving, so the Ferengi saw two Stargazers. Even if they had figured out that the new image was the genuine one in time, it would have been too late, as the Stargazer opened fire as soon as it dropped out of warp, and the Ferengi ship had no time to maneuver out of the way before the phasers and photon torpedoes hit. The Ferengi ship was destroyed. This technique was so successful that it was named after Picard, and there was no known defense against it until 2364.
During the Battle of Maxia, Captian Picard was in control of the Stargazer & invented a battle tactic called the Picard Maneuver and destroyed the Ferengi ship.
