Morphy against Hampton, London 1858 — a casual Evans Gambit. Notes by Löwenthal.
9…Nf6The move ordinarily adopted here is B. to K. Kt's 5th, but if White reply to that move with Q. to R's 4th, the difficulty of the defence is increased. An analysis of this variation, by Fraser, has been given in the "Chess Player's Chronicle," vol. iii, New Series, p. 137.
11.Ba3This is always an embarrassing move for the second player, as it seriously retards the development of his pieces.
12.Qb3The commencement of an attack which, considering the freedom of White's forces, must soon prove decisive.
12…Bh5If Q. to Q's 2nd, the game becomes still more in White's favour, by his playing Kt. takes P., &c.
13…Ng4Kt. to Q. R's 4th would have led to nothing better.
15.e6Played with all Mr. Morphy's wonted decision and acumen.
