In the following outline of fifty of the openings, only the first four moves are given, and usually only one variation is selected, the object being more to give the student an idea of the development than to exhaust the subject. The arrangement is alphabetical, that being more convenient in a book of reference. For the continuations the student is recommended to study “Freeborough,” or the “Handbuch des Schachspiels.”
