The first of two games at the odds of the Queen's Knight between Morphy and Mr. Theodor Lichtenhein, of New York, played in their 1859 match — an Evans's Gambit.
6…Nf6This, as most of our readers are probably aware, is a bad move at this point, after having retreated K's B. to B's 4th. Preceded by 5. K. B. to R's 4th it is the best play at Black's command. The correct move in the present case is 6. P. to Q's 3rd.
9.Ba39. P. to K's 5th, or 9. P. to Q's 5th is the usual move. But we have found, in practice, that 9. Q. B. to R's 3rd is at least as effective.
11…Be6Had Black moved 11. Q. to Q's 2nd, the game would have been continued as follows:— 11. Q. to Q's 2nd; 12. Kt. takes K's P, Kt. takes Kt; 13. P. takes Kt, Kt. to K's 5th or Kt's 5th; 14. Q. R. to Q's sq., Q. to K. B's 4th; 15. B. takes B's P. (ch.), Q. takes B.; 16. R. to Q's 8th (ch.), K. takes R.; 17. Q. takes Q. With a winning game.
19…c5If— 19. B. takes B's P. (ch.); 20. K. to R's sq., B. takes K's R.; 21. R. takes B. And Black cannot save the game.
25…Bd625. K. to B's 2nd would have somewhat prolonged the contest, but could not have affected the final result.
