Barnes against Morphy — a casual Ruy Lopez from the London 1858 offhand series. From an up-hill defence Morphy conducts the close most skilfully and forces the mate.
3…Nf6P. to Q. R's 3rd, and then Kt. to K. B's 3rd, is a more advisable defence, and, indeed, forms the most satisfactory foil to the "Ruy" which has yet been promulgated.
10.Nc3P. to K. B's 4th would have been a more attacking move.
11…f6We have already more than once noticed in Mr. Morphy's game, that after castling, he takes the earliest opportunity of advancing the K. B's P. Such a mode of play is correct in principle, as it frees the K's R., and, in the hands of a master, is usually productive of decided advantages.
