Why filter random positions based on Capablanca' extended board?
Let's talk first on FRC (I have written a small book on that in German
language). One main intention to create FRC (or Chess960) has been to
make
it impossible to provide a complete opening theory for each position.
Thus
the number of 960 distinct starting positions is helpful to reach that
goal. Uncovered pawns are not that problematic because any situation will
have to be set up randomly very short before a game starts.
Looking at the Shogi game there are indeed three uncovered pawns in the
beginning and the game still does exist today.
Capablanca's chess is somehow different to that because of the huge
number of possible starting arrays viewing all shuffled combinations. But
during the history from Carrera to Bird, Capablanca [through to
contemporary versions] it
has been a point of critic and missing acceptance of that extended board.
So it could not be counter productive to select special starting arrays
which seem to be positionally better constructed, without reducing the
huge number of possible initial positions too much.
That leads to the both new rules: a) placing Queen and Archbishop
(Archangel) at different colored squares, and b) avoiding unprotected
pawns. I cannot see any negative payload connected with this two
additional demands. More then 20.000 possibilities should be sufficient.
Also see a nice SMIRF (providing both: FRC and CRC) preview at:
