Schiller, Hooper and Whyld also noted that the Colle is unfashionable in master play. Van der Sterren concurred with Benjamin and Schiller that the Colle is a fine opening "for those who want to keep the opening as simple as possible", and also echoed their remark that White's plan is to play e4 in the near future. History Colle and Koltanowski each won several tournaments in the 1920s and 1930s. Colle finished ahead of Tartakower, Euwe, and Rubinstein at various times. The opening had even been referred to as the "dreaded" Colle System. George Koltanowski, in his book The Colle System, said it offered "solid development", combinations, and a decent endgame, giving White "good chances of not losing against a stronger player". Players like Capablanca and Tal found ways to take the sting out of some of its various lines, however. One such line that has been tested is 3...Bf5, sometimes called the "Anti-Colle". Magnus Carlsen lost the only game with the white pieces during his five world championship matches, when he played the Colle-Zukertort System in game 8 of the World Chess Championship 2016 against Sergey Karjakin. Colle–Zukertort System One variation of the Colle is the Colle–Zukertort System (named after Johannes Zukertort), characterized by developing the dark-squared bishop on b2. The typical plan is: 1.d4 d5 2.Nf3 e6 3.e3 Nf6 4.Bd3 c5 5.b3 Nc6 6.0-0 Bd6 7.Bb2 0-0, where White, despite their apparently innocuous development, will eventually play for a kingside attack. This system has been frequently employed at grandmaster level by Artur Yusupov. Games A famous Colle System win featuring a slightly unusual Greek gift sacrifice is Colle–O'Hanlon, 1930. Analysts have debated the theoretical soundness of this sacrifice for many years. 1.d4 d5 2.Nf3 Nf6 3.e3 c5 4.c3 e6 5.Bd3 Bd6 6.Nbd2 Nbd7 7.0-0 0-0 8.Re1 Re8 9.e4 dxe4 10.Nxe4 Nxe4 11.Bxe4 cxd4 12.Bxh7+ Kxh7 13.Ng5+ Kg6 14.h4 Rh8 15.Rxe6+ Nf6 16.h5+ Kh6 17.Rxd6 Qa5 18.Nxf7+ Kh7 19.Ng5+ Kg8 20.Qb3+ (Black resigns) Black has a variety of approaches to counter the Colle System. One of the most dynamic is to aim for a Queen's Indian Defense setup. White's pawn to e4 slashes at empty space, while Black's pieces are poised to undermine White's centre and attack the . The technique is well-illustrated in the 1929 game between Colle and José Capablanca: 1.d4 Nf6 2.Nf3 b6 3.e3 Bb7 4.Nbd2 e6 5.Bd3 c5 6.0-0 Nc6 7.c3 Be7 8.e4 cxd4 9.Nxd4
