In exchange for the gambit pawn, White has a piece developed after 4.Nxc3 and a pawn in the center, while Black has an extra pawn and a central pawn majority. The plan for White is straightforward and consists of placing the bishop on c4 to attack the f7-square, and controlling both the c- and d-files with rooks, taking advantage of the fact that Black can hardly find a suitable place to post their queen. The Smith–Morra is uncommon in grandmaster games, but is popular at club level.〔http://chess.about.com/od/openings/ss/Sicilian_2.htm〕 ==History== The Smith–Morra is named after Pierre Morra (1900–1969) from France,〔(Chess Notes by Edward Winter ), entry 3953 ("Morra")〕 and Ken Smith (1930–1999) of the Dallas Chess Club.〔(Kenneth Ray Smith (1930–1999) ) Obituary at the US Chess Federation〕 Hence in Europe the name Morra Gambit is preferred; names like Tartakower Gambit and Matulovic Gambit have disappeared. Morra published a booklet and several articles about the Smith–Morra around 1950. Smith wrote a total of nine books and forty-nine articles about the gambit. When Smith participated in an international tournament against several top grandmasters in San Antonio in 1972, he essayed the opening three times, against Donald Byrne, Larry Evans, and Henrique Mecking, but lost all three games. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sicilian Defence, Smith–Morra Gambit」の詳細全文を読む スポンサード リンク
