Morphy against Harrwitz — the seventh game of their 1858 Paris match (a Dutch Defence), drawn by perpetual check after Morphy let slip a won game.
8.Bxf6At this point in the 5th game of the match Mr. Harrwitz castled.
11.f4Mr. Harrwitz made a move similar to this in the game just mentioned, which we condemned, as we do this also; on principle it is weak play, as it leaves a Pawn behind unsupported, and in the particular instance before us causes the position very quickly to turn in favour of the second player.
14.Rae1This also is a weak move.
14…Bh4As usual, taking immediate advantage of his opponent's slight error; whether White in reply play Kt. to his 3rd, or P. to K. Kt's 3rd, he gets a bad game.
21…Qf7Anticipating the advance of the K. Kt's P.
22.Be2Mr. Harrwitz might have thrown forward the K. Kt's P., and had he done so, a very interesting variation would have arisen. Black could not have taken it on account of B. takes P. (ch.), &c., nor could he have taken Q's P. with the Kt., as B. to Q. B's 4th would have won a piece.
23…Nf6The correct move, for of course White dare not take the Pawn.
30.Bh5An excellent move.
31.Re1Had White taken the Rook, he would have been mated in a few moves by Q. to R's 8th (ch.), &c.
32.Bf3Mr. Harrwitz evinced judgment in sacrificing the Pawn, for any attempt to save it would have involved him in difficulty.
33…Qe5Black has now a Pawn a-head, and a position so superior as to render victory almost a certainty.
38…Rh7Mr. Morphy plays all this with his customary precision.
39…Qb2Threatening to win the Queen.
41…Rf1+The main feature of Mr. Morphy's play is that it is so free from mistakes. This, however, was evidently an oversight, and throws away a victory which would have been won with ease had he taken Rook with Rook.
44…Qe5+And perpetual check existing, the game was declared drawn.
