As someone who has taught symbolic logic, I find it far less opaque than
Betza's funny notation. Operators and puncuation make things clearer. I
spent this afternoon devising a new notation. I'll post the examples of
the notatation here, and I'll post a tutorial on it later. See if you can
figure things out without the legend at the end.

Wazir: O
Ferz: D
Alfil: DF
Dabbaba: OF
Knight: OFT
Camel: OFFT or OTFF
Zebra: OFTFF or OFFTF
Giraffe: OFFFT or OTFFF
Chinese Knight: OeFT
Rook: O*
Bishop: D*
Queen: O*|D*
Nightrider: (OFT)*
Alfilrider: (DD)*
Dabbabarider: (OO)*
Marshall: O*|OFT
Paladin: D*|OFT
Grasshopper: (O|D)*pF
Korean Cannon: O*pF*
Chinese Cannon: O*e|O*pF*o
Vao: D*e|D*pF*o
Leo: ((O|D)*e)|((O|D)*pF*o)
Chinese Elephant: DeF
Nightriderhopper: (OFT)*p?
Long Leaper: ((O|D)!)*e
Withdrawer: ((O|D)!)BF*e

In case it helps, here is a brief legend of symbols used in these
examples.

| = disjunction operator, separating options
O = disjunction of all orthogonal directions
D = disjunction of all diagonal directions
F = relative forward direction
T = (L|R)
L = relative left direction
R = relative right direction
B = relative backward direction
? = optional, conditional repetition of last move
* = infinite ?s
e = continue move only if space is empty
o = continue move only if opponent on space
p = continue move only if piece on space
! = capture piece here
() = punctuation

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.
