The concept is expandable. At the maximum, it could look like this:
In this level, 16 new squares would be created. The game could then be called Chess 80, or in another notation Chess 64/16. Of course, intermediate levels between Chess 66 and Chess 80 are conceivable.
In the following example, moves can be made not only forked as in Chess 66, but triple-forked moves become possible.
Such an extended concept certainly leads to the question of playability. But it might be interesting to think about it.
