Two questions:

1.  May a piece which promoted move out of a citadel, move back in on a
later turn, and promote again?  There are three possibilities for this:


2.  Let's see if I understand promotion zones:

A.  Either citadel on the enemy side may be used by any piece which has a
level to which to promote.

B.  A bishop may also promote on the square orthogonally adjacent to an
enemy citadel.  (In other words, a colourbound bishop still has two
promotion spaces.)

C.  A pawn may also promote on b2(b7) or k2(k7).

3.  The ZRF is barely started, but if you want to send me your email addy
(mine is on the feedback page) I can send you a screenshot or two of the
graphics I did for this.  I went with an unchequered board to supplement
your historical feel.

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:

Block quote

Second paragraph in block quote

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.
Here is some preformatted text.
  This line begins with some indentation.
    This begins with even more indentation.
And this line has no indentation.
