Keys "s"=save "l"=load "b"=back once
Variant by Edward Jackman. Pieces may make non-capturing moves anywhere. Exceptions: Pawns cannot go to their first ranks, and must move to the queening rank normally. Kings may only move normally. To check (directly or by discovery), you must make a standard move.
These are simple illustrations rather than strong opponents.
