The purpose of this note is to summarize and expound the results of three papers on information in extensive games, particularly the third, as they apply to the problem of simplifying the solution of multi-move games. The special terminology of these papers (necessary for the formal development of the theory but likely to be misleading or obscure 1n the present context) is avoided where possible. Thus the term. "pattern of information" is used, but only where the intuitive meaning agrees with the precise definitions.
