Of the 20 or 30 clusters we can divide CVs into, Absorption Chess derivatives form a major one after number one Carrera-Birds. In the last comment here, Shvorin mentions two other derivatives, out of over a hundred members so far published, Confederation and Fusion. Some Absorption derivatives are part of a larger theme, or otherwise multifaceted, or rely on mechanism besides immediate capture for change of movement power; probably for example we include Pocket Mutation as subvariant of Absorption for the sake of complete classification into 2 or 3 dozen clusters. (In the full taxonomy, a given CV may be member of two clusters, but try to avoid three.) In Shvorin's preferred embodiment, Hybrid same-side units same-type may even coalesce, he answers Strong in another of these 6 comments. That could be a factor in Stalemate or easily-imaginable convenience, such as getting two Rooks to the other side on one square, where they then re-divide.
