Morphy giving the odds of his Queen's Rook against an amateur — a Two Bishops' (Bishop's) Opening. From his 12th move Morphy plays a capital series of moves. Notes by Löwenthal.
3…exd4The correct move is B. takes P.
12.Nxh7From this point a capital series of moves is played by Mr. Morphy.
15.Nf3All this deserves the student's best attention.
15…Qe8If the Queen had taken the K's P., White would have had a forcible reply in B. takes Kt., &c.
22…Kg8The utmost accuracy pervades the whole of White's combination, which is of a very high order.
