pallab basu writes last year about going on 8-year-old Rococo, ''Rococo is one of the best non-chess like chess variants. All the problems of Ultima have been successfully dealt with.'' I agree. We have been omitting by accident *Rococo* and *Tetrahedral* Chess from our list of 20-50 CVs for emerging, not entirely hypothetical entities to develop. I would constructively add: (1) Forget the variants Aronson added later. They worsen it, except mirror array doesn't matter. (2) The fact that Cannon Pawns are only used one other time and that anything like border squares are rare before or after D.O.I. show respect recorded for this old classic. (3) Ambiguities are more easily resolved in cases involving Long Leaper and Chameleon pieces on the main board than for border squares themselves for pieces generally. I am pretty sure I could set up some positions involving borders that Zillions or some other thing would respond to differently from what we intend. Some of the border aspect needs further resolution. (5) Repeating somewhat, it's hard to exaggerate the brilliance and effectiveness of wonderful Cannon Pawn. (not to sound like Jeremy Good in hyperbole)
