Based upon the precarious assumption that the standard 8H x 8W game
of chess possesses a unique veracity in its design due to its
characteristic pawn coverage of its 2 most valuable pieces,
here is what the standard 8H x 10W game must look like:

R-N-C-B-Q-K-B-A-N-R
R-N-A-B-K-Q-B-C-N-R

Out of the 26,000+ available Capablanca Random Chess opening setups,
there are only 2 select opening setups (E-W mirror images of one
another) for which:

1. The 3 pawns adjacent to the most valuable piece (i.e., the king)
are backed-up the maximum times possible (4 vertical, 4 diagonal,
3 diagonal).

2. The 3 pawns adjacent to the 2nd most valuable piece
(i.e., the queen) are backed-up the maximum times possible
(4 vertical, 4 diagonal, 2 diagonal) AFTER meeting condition #1.
________________________________________________________________

The only other restriction is that E-W symmetry in the opening setup
is given wherever pairs of pieces exist.

There are 21 pawn coverages used out of a maximum possible 23
available. So, 2 pawn coverages are "wasted". Individually,
some pawns have a minimum of zero coverages while some pawns have a
maximum of 4 coverages with an average of 2.1 coverages.

I am not generally interested in games of this class. This is merely
another puzzle-solving exercise to me. I leave the christening to
someone else.
