This is a quick approximation:

It enforces the rules (except that e.p. capture does not work, but this would have to be solved in the included library file). It doesn't properly highlight legal moves, though.

It is not clear to me whether this variants employs the check rule; the explanation of mandatory capture suggests it has not, as it talks about capturing the King. An alternative would be to consider the position a checkmate, as you only can do the capture with the edge piece, and it does not resolve the check.

The betza.txt library should have some feature similar to the BadZone hook for the Interactive Diagram, where the user can define a function to enforce confinement of pieces to zones. When such a function is defined each generated move should call it to check whether the move obeys the confinement rules.

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