Kennicott against Morphy, New York 1857 — a casual Scotch Gambit. Notes by Löwenthal.
5.Ng5This is far from being an effective mode of proceeding with the attack, and is decidedly inferior to Castling.
9…d6P. to Q's 4th, the invention of Schumoff and Cochrane, and for which see "Chess Player's Chronicle," vol. ii. p. 215, is now deemed the correct defence.
10.Qb5Heydebrand gives 10. P. to Q. R's 3rd, and then makes White play 11. Q. to Q's 3rd, and considers the game even.
15.f5White has now a strong attack, and no little care is required to parry it effectually.
19…Qe3+Finishing the game in the best and speediest manner.
