In Lessons in the Fundamentals of Go, Kageyama says that if you can't win playing an enclosure-and-extension fuseki, you should adapt your opening to your own playing style. Pros and strong amateurs often play openings which differ from the classical "enclosure and extension" pattern.
Many examples from the New Fuseki era exist, of course, but that seems to have settled down in the latter half of the Twentieth Century. Periodically, though, you run into exceptions.
Examples From Pro Games
- Lee Changho vs. Paek Tae-hyeon: Lee plays double 3-5 6-4 enclosures.
- Hoshino Masaki vs. Tsurumaru Keiichi: a three-corner sanrensei versus a "tengen shimari."
- Takao Shinji vs. Yamashita Keigo: Takao plays 5-5, and Yamashita replies with tengen. It gets weirder.
- Yoda Norimoto vs. Kobayashi Satoru: Yoda plays double 6-4 points.
- Zhang Wendong vs. Liao Xingwen: Zhang 9-dan may be a bit of a bully.
- Yamabe Toshiro vs. Hashimoto Utaro: Yamabe plays tengen. Hashimoto immediately approaches. Arguably part of the New Fuseki era, this game is odd even for that period.
- Gan Siyang vs. Li Fan: Gan Siyang plays a unique move as Black 1.
Pros Noted for Unusual Openings
- Yang Keon plays experimental corner moves often.
- O Meien is also noted for original moves, though his fuseki isn't always non-standard. His innovations are called "Meienisms."
- More: see Center oriented players
- The Great Wall is an unorthodox fuseki advocated by Bruce Wilcox.
- groep on KGS(6 dan) always plays a variation of the Great Wall where he spends his first 8 moves playing K3, K5, etc up to K17
- High55 on KGS(6 dan) usually plays his first two moves on facing 6-4 points.
- "Stanley," as mentioned above, plays a very unusual fuseki in conjunction with a greedy, overplaying style.
- Davou played an unusual tengen fuseki in a rengo with a 7-dan player.
- Ongoing Game 2, a Wiki rengo, featured an unusual enclosure based on an immediate approach and mokuhazushi.
- hoshionly on KGS plays only star points in the opening, except to protect his star points from being captured. This is unusual because he will even contact 3-4 point stones to get the hoshi, and then tenuki. He then goes on to spectacularly kill most of the board.
- rowurboat on KGS plays five in a row in the centre, then claims victory. Then there is a lot of fighting.
- sevenseven on KGS plays the 7-7 point in the opening.
- Robert Jasiek's play is often very center-orientated: sum
- Ohashi Hirofumi 6p (大橋拓文) has a video introducing several openings, The Black Hole (ブラックホール) on all four 7-7 points, The Milky Way (天の川), and Orion's belt (オリオン座).
- Another "Black Hole" opening, but forming a square using four 5-7 points, is demonstrated at Black hole in the universe of Go - Haylee's Live Go 63 - YouTube.
- Sofia fuseki
Some of these experiments are consistent with the idea that you should have no plan in the opening. Others just seem playful.
