I understand. Don't start attacking until you've developed all your pieces. Pretty good general rule, but if my opponent is open to a mating attack or leaves material hanging, I'll happily munch on every tasty morsel they give me, even if I'm not fully developed. 😀
I had came up with 2 rules of my own, although of course the chess world will never see them.
These are as follows:
1. Dismissal
If one of your pawns has not yet been committed to the battlefield i.e. still on it's "home square"
then it can simply be removed from the board.
This is called a 'dismissal', possibly noted as, say for example Df2 if White wished to remove the pawn on f2 to open up the castled Rook's file.
This move drops a pawn, but could open up lines of attack against the enemy King,
and which can be played at any time (except if resulting in check against own King).
2.Demotion
To spice things up a bit, a Knight or Bishop on the 7th rank (opponent's 2nd rank) could be demoted to a pawn,
and so being one step away from Queening.
I've given this one less thought than the 1st rule, but sounds fun either way.
my father, who taught me the game, would say "en garde" whenever my queen was threatened
kept me from hanging many a queen
it would become an unwritten rule
