Unsolved Openings
All opening names come from FM Arimakat, tolius, or were popularized within the community.
All of these openings provide interesting midgames and endgames, considering they are unsolved. This makes it so that there isn’t one specific, popular engine line is played every time against the opening, and many games differ from each other. Some of these openings are still used at the top level. Although not as popular as 1.e3, most of these openings are still used in top level play including in the ACWC.
If you notice any openings that do not appear on here that are seen quite frequently, be sure to contact one of the members on the steering committee for more information.
