The third and last game of the first-round match, which Anderssen won with the Black pieces to complete his victory over Kieseritzky. Staunton faults White's twelfth move as "badly played," after which "Mr. Anderssen loses no time in taking advantage of his opponent's error, and from this moment has the battle all his own way."
12.f4Badly played. If, instead of this move, he had quietly advanced P. to K. Kt.'s 3rd, the game, from the better development of his men, would have been in his favour.
12…e5Mr. Anderssen loses no time in taking advantage of his opponent's error, and from this moment has the battle all his own way.
14.Nc2This facilitates Black's victory. Better to have played the Kt. to K. B's 3rd, bad as that would have been, than make the present move, which leads to obvious ruin.
15…Bg4Merciless! White must now lose a piece, do what he will.
