In the "Lesson of the Week" posted for this week, reference was made to a line attributed to Gioachino Greco. A search of the ChessBase database fails to turn up this game. The absence of documentation in Garry Kasparov's My Great Predecessors renders my source text useless for tracking its sources.* Fortunately, a well-known English edition of Greco's games is readily available through Google Books, which digitized a copy that is held in the Harvard University Library: Professor Hoffmann, trans. and ed., The Games of Greco (London: George Routledge & Sons, 1900).**
Here, I present the game complete as found in Hoffmann with additional notes that I have added. The game also is present in William Lewis, Gioachino Greco on the Game of Chess (London: Longman, Hurst, Rees, Orme, and Brown, 1819) as the third variation of game nine (35). This text is digitized by Google from the Frank J. Marshall Collection at the New York Public Library.
1.e4 e5 2.Nf3 d6 3.Bc4
Morphy's game at the Paris Opera continued with 3.d4.
3...Bg4 4.h3 Bxf3 5.Qxf3 Qf6
Lewis and Hoffmann both comment that Qd7 is better.
6.Qb3 b6 7.Nc3
Black to move
ChessBase has Greco's game continuing 7...c6 8.Nd5 Qd8 9.Nxb6 Qxb6 10.Bxf7+ Kd7 11.Bxg8 d5 12.exd5 Qxb3 13.dxc6+ Nxc6 14.Bxb3 1-0. Greco presented each variation as a separate game. Later editors of his work arranged the games by opening and treated similar games as variations. There is very little reason to believe that any of his games were from actual play, but that all were created for instructive purposes. Whether ChessBase should include any is as important as questioning why some are excluded.
7...Ne7 8.Nb5 Na6 9.Qa4 Nc5
White to move
10.Nxd6+ Kd8 11.Qe8#
This game is a worthy addition to the database, and merits memorization for those inclined to the study of miniatures.
*The first three volumes of My Great Predecessors contain no footnotes, bibliography, nor any other references to source material beyond the abbreviated attributions in the text itself. Volumes IV and V each contain a two page bibliography listing Russian sources and non-Russian sources. No text of Greco's games appears in either list.
