The Halloween Gambit (also known as the Müller–Schulze Gambit or Leipzig Gambit) is an aggressive chess opening gambit in which White sacrifices a knight early-on for a single pawn. The opening is an offshoot of the normally staid Four Knights Game and is defined by the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Nc3 Nf6 :4. Nxe5 The theoretician Oskar Cordel reported in 1888 that Leipzig club players used the opening to dangerous effect, but he did not believe it was sound. Their name for it, ''Gambit Müller und Schulze'', was not after any players by those names, but rather a jocular German equivalent of "Smith and Jones", or, "Tom, Dick, and Harry". White's objective is to seize the center with pawns and drive back Black's knights. After 4... Nxe5, White usually plays 5. d4 (5.f4 does nothing for his development), after which Black can retreat the attacked knight to either g6 or c6. ==5...Ng6 retreat== When Black retreats 5...Ng6, White chases the f6-knight with 6.e5. Then after 6...Ng8 7.Bc4, former world champion Max Euwe recommended 7...d5 8.Bxd5 c6, contending in volume 11 of his opening series that Black has a decisive advantage.〔 Instead of holding on to the extra piece with the usual 6...Ng8, a more logical continuation according to Eric Schiller is 6...Bb4, giving Black the better game after 7.exf6 Qxf6 with a lead in development and pressure in the center. 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「Halloween Gambit」の詳細全文を読む スポンサード リンク
