You're not understanding my argument.
A queen cannot move like a knight 'cuz the rules say so.
It's about the word move combined w/ the ability to retract piece moves.
Would you allow uncaptures as well? Would an e.p. uncapture be available only on the move after an e.p. capture? Would pawns promote on their back rank or would that be limited to the far rank? Would unpromotion be limited to pieces that had appeared by promotion or could you unpromote one of your original knights and promote it to a queen the move after?
All very interesting.
Don"t worry. This forum is filled with impatient people, so expect it LOL
