[usjggqce] variations on the theme of pawn

pawns capture colorbound but change color for normal moves.  more such fairy chess pieces:

move like wazir, capture like ferz.  previously, also removing sideways moves.

move like knight, capture like dabbaba.  perhaps nice to combine with previous.  also capture like alfil?

move like rook (not necessarily changing color), capture like bishop.  this is a weakened queen.

the other way: regular movement preserves color; capturing changes color.
