If there were ratings on comments (not my first use of this hypothesis)
Robert Shimmin's would deserve an Excellent. It should perhaps be
included as a notes section in the otherwise short text. Each subset
comprises cells a sideways Dabbaba or f/b Camel move away -- contrast the
subset which is the whole of a Heavenly Horse's binding, cells a
sideways
Dabbaba or f/b Knight move away.
I suspect that the big future use of the Crab may be in Fusion-style
variants, where it can combine with other pieces to take short cuts. This
would also be true of equivalent pieces on other types of oblique -- a
Cram, with the corresponding Camel moves (Cram to Camel as Crab to
Caballo!) would have a cycle of 10 moves without such a feature.
