Even when the exact ramifications of the actions taken by a player are not totally understood, the result is some tactical play, good or bad.
Tactics are short term play executions.
When a series of simple atomic tactical decisions are linked together in some harmonious execution involving several players, the whole series can be described as a tactical play or maneuver. As soon as players start playing the game, their tactical development begins. However, tactical training is a gradual process, one that has to be at the correct pace for the player to understand and perform technically. If the player does not have the proper groundwork and preparation, the player will not be able to take the tactic worked on in training to the playing field. The coach defines an overall team strategy or system of play.
