Notes:
(1) The bonus value has not been carefully tested, so it may be possible
to find slightly better values.
(2) Plan is to now try adding similar restriction for pawns. I wanted to
include that as part of this pull request, but I was advised to do it as
two separate pull requests. STC is currently running here, but may not add
enough value to pass green.
