By the way, I decided to implement this opening requires that map feature without defaults, like this: If the opening specifies a feature, like "island": "yes", then the feature value is required. If it doesn’t specify, then there is no default value; the map may have the feature or not, the opening doesn’t care. So far it’s as described before, and now I add one more idea: Island openings are playable on non-island maps. They are unlikely to be a good idea, but it will happen against some opponents (I proved it by test). Simply give them a low probability of being played. On an island map, everything else is disallowed, and you get an island opening. On a non-island map, you usually get a usual opening, but occasionally Steamhammer will try out an island opening to see if the opponent is weak to it.
