When one strategy, say A, is uniformly worse for a player than another, say B, we say that A is dominated by B. If such is the case, that player will never use A, although whether he uses B remains to be seen. The other player can confidently proceed in thinking on this basis; in particular, he need not consider playing a strategy that is the best response only to A. When solving the game, we can remove dominated strategies from consideration. This reduces the size of the game table and simplifies the analysis.*
