Marache against Morphy, New York 1857 — a casual Evans Gambit finishing with a smothered mate. Notes by Löwenthal.
8.exd6We should have preferred playing B. to Q. Kt's 5th.
10.Ng5Weak; 10. B. to Q. R's 3rd, followed by 11. R. to K's sq., appears the proper line of play.
11…Bf5Decidedly the best move. Black purposely gives up the exchange, foreseeing that he must remain with more than an equivalent in Pawns and position.
18…Ncd4The position here is one of much interest, and a diagram of it is appended, to enable students to play over the variations without retracing the previous part of the game. White has the choice of three moves besides the one in the text — Q. to Q's 3rd, R. to Q's sq., or Q. to Q. R's 4th — each of which is shown to lose.
