If I recall/recognize the diagram correctly, at the diagram's bottom e.g. 'Ae' indicates (4D) Board column A and (2D) board file e. The labels at the sides e.g. '15' indicates (4D) Board row 1 and (2D) board rank 5 (a column being like a file by my understanding). True for both the rules page diagram and the preset diagram.

edit: I had to re-read the labelling by zooming in on the bottom of the diagram, so I could tell lower case letters apart from numbers - my eyesight/laptop's not the greatest, maybe. Also, there are over half a dozen 4D CVs in the database, as I recall seeing (I got a few of my own published over the years). Not as many as there are 3D CVs, true.

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.
