Morphy against Harrwitz — the fourth game of their 1858 Paris match (Philidor's Defence).
4…Nc6This move is not to be recommended, the proper defence being B. to Q's 2nd.
7.Bg5Mr. Morphy in playing this opening has so frequently adopted this move here that it is evident he considers it forcible. It was first played by the editor when engaged in his match with Mr. Harrwitz.
11.Rad1White has now an excellent game, every piece in play and well posted.
12…Rf7We should have preferred playing K. to R's sq.
13.Nd4P. to K's 5th would have produced some highly interesting variations, e.g.,— 13. P. to K's 5th, Q. to K. B's 4th; 14. P. to K's 6th, R. to K. B's sq; 15. K. R. to K's sq, Q. R. to Q's sq; 16. Kt. to Q's 5th, B. takes Kt (best); 17. B. takes B., winning at least a Pawn.
27…Rc7Had the Queen captured the Pawn, White would have gained a decided advantage, e.g.,— 28. R. takes P. (ch.), K. takes R.; 29. Q. to R's 5th (ch.), B. to R's 3rd; 30. Kt. takes B., R. takes Kt.; 31. Q. to B's 5th (ch.), K. to Kt's 2nd; 32. Q. takes R., with a won game.
30.c5The winning move, and one of a very high order, followed up too with Mr. Morphy's wonted accuracy and ingenuity.
35.Nxd6And wins.
