The Boden-Kieseritzky-Morphy Gambit is lightly regarded and is never played by grandmasters, but it has one of the best records for White of any opening played below the master level. It scores a phenomenal 62% in all games in the chess databases. This book examines an opening which can be quite useful for beginners and amateur chess players. The gambit we will examine (1.e4 e5 2.Bc4 Nf6 3.Nf3!? or 1.e4 e5 2.Nf3 Nc6 3.Bc4!?) has been used by Paul Morphy among other strong players. In my view it is as good a gambit as most others.
