Rethinking arrays, in c960 if keeping King and Queen central, there are
only rnb, rbn, brn, bnr, nrb, nbr, for 6 symmetrical, and they're all good on 8x8. Others with the Rooks' boxing in King too, with unsymmetrical included now too, number all together the 6x6, or 36, and they're all okay.
Keeping k and q at d1 and e1 might be next in importance to what Fischer
already implemented, castling to c1 and g1. In rnbf on 8x10, there should
probably be all 24 starting arrays with k and q central, xxxxQKxxxx, but
keeping the two xxxx reflecting each other all the time, symmetrically. A couple of the 24
are not so good, such as a Bishop immediately hitting an unprotected Pawn,
but Abdul-Rahman and I had too few before with our only 5-10.
Many c960 have Bishop (and Q) from array attacking unprotected Pawn after one pawn move, even within the 36 above.
