and a game loss. Experienced players of strategy games will memorize build orders, as it gives them a significant advantage over players who are not familiar with build orders. This is particularly important in games where there is a resource cap such as food in the WarCraft series or supply in the StarCraft series, as a player must know how much remaining supply they have to work with for a given build order. Since the game mechanics will not permit players to build past this limit without additional resource structures the build order and the timing of new construction must be implemented in a very precise manner. Build orders involve all forms of resource management, including unit production and control. The loss of a unit or the overproduction of another may delay or change the course of a build order. Complex build orders that involve a combination of key units may fail completely due to improper unit control, despite correct development of buildings and technology research. In professional and competitive tournaments it is implicit that before a match each player will have studied his opponent's recent public games in order to prepare an appropriate build order to defeat his style. Since both players understand that each side will be doing this it can create interesting situations – for example: a defense-oriented player could pretend to be using his traditional strategy to fool his opponent, while instead creating an offensive force in a hard-to-spot position. This makes competitive strategy gaming as much a guessing of what your opponent is trying to do as it is on focusing on your own strategy in order to win. This sort of play is often called mind games by narrators and commentators and it often happens that a bad "read" on an opponent's intentions is enough to lose a match.
