Morphy against Boden, London 1858 — a casual Two Knights' Defence. Notes by Löwenthal.
12…Qe7This is a very good move of Black's, as Mr. Morphy observed, for it threatens, if White castles, to play P. to K's 5th, and then Q. to K's 4th.
13.Qd2To have Castled would not have been judicious.
19.Rxf3Had White taken B. with Q. he would have lost the exchange.
19…Qh4The move of Q. to K. Kt's 3rd has some recommendations, but the objection to it is White's replying with R. to K. B's 5th; by playing Q. to R's 5th Black insures the regain of his Pawn, though in rather embarrassing circumstances.
24.Kb1White now threatens to take K. R's P. with B., which he evidently could not, whilst the K. stood at Q. B's sq.
25…Kf7These last are the best moves.
26…Ke7The only hastily played move, and the one which costs Black the game; by moving K. R. to K. R's sq. he would have had an equal game.
27.Qe1Threatening to move next Q. to K. B's sq., and then R. to K. R's 3rd.
27…Bf4The only move to save the Queen.
28…Rg8Played in order to be able to move P. to K. B's 4th. Had Black taken B. with B., White would have retaken with Pawn, and then won the Queen by Q. R. to K. Kt's 3rd.
29…g5This seems correct, as Black is menaced with the loss of his Bishop by White's moving Q. R. to K. R's 3rd.
38.Rd7Threatening the fatal advance of P. to Q's 6th, which he could not play before, as Black would have checked with Q. at Q's 8th, and then taken the Pawn. The ending is all very neatly played.
