We need to look at the geometry of the chesspieces. Rook, Knight, and Bishop each attack different squares. Let us start with one exceptional case: if promotion to any one of Rook, Knight, Bishop results in a stalemate, than so does promotion to any of the compound pieces Amazon, Marshall, Queen, or Janus. Assuming that the situation is not that bad: [1] if promoting to a Rook stalemates - choose a Janus, [2] if promoting to a Knight stalemates - choose a Queen, [3] if promoting to a Bishop stalemates - choose a Marshall. <p> As for the Amazon - it is just too strong for my taste. I prefer to have just the three pieces (Marshall, Queen, Janus) to choose from. Actually I use the Unicorn (Bishop + Nightrider) instead of the Janus (Bishop + Knight) in my own chess variants.

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

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.
