Morphy against the Duke of Brunswick and Count Isouard — the celebrated game played at the Italian Opera in Paris, 1858 (Philidor's Defence).
8.Nc3B. takes P. (ch.), followed by Q. takes Kt's P., might have been played with advantage, but the line of play adopted by Mr. Morphy led to something much more decisive.
10.Nxb5The natural move here was B. to Q's 5th, and most players would have adopted it; but, as will be seen on an examination of the annexed diagram, the young champion devised a scheme of attack altogether superior to the one suggested.
12…Rd8Can any better move be found?
14…Qe6There is no other resource.
16.Qb8+This sacrifice adds greatly to the beauty of the whole combination, and produces a most artistic finish. The student will do well to look closely into Mr. Morphy's 10th move and those that follow, which display a depth and accuracy to which too high praise cannot be awarded.
