Rifle Chess can be saved by the addition of reaction fire.

For example, if the Qh5 shoots Pg6, Pg6 can shoot back and kill
the Queen, even though it was not his turn to move; as per the csipgs game
'Perfect General' and other such games.

This was part of my game Autorifle Chess from the 1970s -- a
barely-playable game whose reason for existence was as a demonstration
that not only could rifle be saved but even autorifle could be saved!
(Just showing off, I was.)

In straight Rifle Chess, I'd add the restriction that you get no reaction
fire if your last move included a capture -- again, according to several
csipgs games.
