NM Dan Heisman gives a definition for chess tactics and discusses that the main use for tactics is not to win material or checkmate, but to check whether your candidate moves allow your opponent a tactic on the next move. This is presented through several examples. Dan also defines defensive tactics. There is a slight glitch for a couple of seconds in the middle of the video.
