Daniil Frolov has the right idea, and his referencing 007 Chess actually has to do with Arimaa. That is, what gives arimaa its 15,000 or so average alternative moves per turn comes from the plural moving each turn. Just find suitable multi-move CVs from above index, and those CVs arguably present the same difficulty for Computer as arimaa; research can then find which ones actually do. Approximation of how many moves are available in some sample CVs from multi-move category is instructive. Argument can also develop two other ways: (1) use CVs only from Progressive sub-category; (2) Apply Mutator of requiring up to four moves per turn on any CVs having mostly short-range piece-types, as Frolov is implying in mention at 007 Chess.
