For anyone interested (because it took me quite a while to figure out and then code), below is GAME Code for a rule enforcing Rose piece that is designated RO (white) and ro (black).  These can probably be condensed to an easier to read code, but it should function perfectly.

//define each move a knight can make as a direction
map ro1 1 2;
map ro2 -1 2;
map ro3 1 -2;
map ro4 -1 -2;
map ro5 2 1;
map ro6 -2 1;
map ro7 2 -1;
map ro8 -2 -1;

//Create a function for each of the 16 moves a Rose can make
def ROA1 logride #0 #1 (ro1 ro5 ro7 ro3 ro4 ro8 ro6);
def ROA2 logride #0 #1 (ro1 ro2 ro6 ro8 ro4 ro3 ro7);
def ROB1 logride #0 #1 (ro5 ro7 ro3 ro4 ro8 ro6 ro2);
def ROB2 logride #0 #1 (ro5 ro1 ro2 ro6 ro8 ro4 ro3);
def ROC1 logride #0 #1 (ro7 ro3 ro4 ro8 ro6 ro2 ro1);
def ROC2 logride #0 #1 (ro7 ro5 ro1 ro2 ro6 ro8 ro4);

Quick Markdown Guide

By default, new comments may be entered as Markdown, simple markup syntax designed to be readable and not look like markup. Comments stored as Markdown will be converted to HTML by Parsedown before displaying them. This follows the Github Flavored Markdown Spec with support for Markdown Extra. For a good overview of Markdown in general, check out the Markdown Guide. Here is a quick comparison of some commonly used Markdown with the rendered result:

Top level header: <H1>

Block quote

Second paragraph in block quote

First Paragraph of response. Italics, bold, and bold italics.

Second Paragraph after blank line. Here is some HTML code mixed in with the Markdown, and here is the same <U>HTML code</U> enclosed by backticks.

Secondary Header: <H2>

  • Unordered list item
  • Second unordered list item
  • New unordered list
    • Nested list item

Third Level header <H3>

  1. An ordered list item.
  2. A second ordered list item with the same number.
  3. A third ordered list item.
