My Twinmove chess, a double move variant, uses mouse moves. I experience no
problems. Perhaps it is because the second move can never be a pawn move(?)
Twinmove Chess (compulsory) and Twinmove Chess (uncompelled)
My pawn promotion code is like this:

   if and var legal and equal rankname dest 8 not or equal Q space dest
     or equal R space dest or equal B space dest equal N space dest;
        askpromote Q R B N;
   endif;
   continuemove;
