Cool, good idea!

I have a couple bits of cosmetic feedback for you:

I would like the chess pieces to appear much larger within each of their squares, ala http://www.365chess.com/opening.php

Also, the green border around protected cells is difficult for me to discern. (Might be due to my colorblindness.)

Cool!

I've been thinking to make the exact same thing in Javascript using Chess.js and Chessboard.js

https://github.com/jhlywa/chess.js/blob/master/README.md http://chessboardjs.com/

I got a half-working version and will opensource the code once it's ready.

I think it could be a nice tool to help people starting with the game, but also as an analysis tool for more advanced players.

[Edit] I just uploaded what I did so far on a server, just in case you want to take a look

http://www.hotpixel.mx/chess/index.html

my idea is to use little icons (now really terrible looking) with numbers and playing with opacity to give an idea of the strength for each square of the board. I still have some problems in some cases displaying incorrect numbers, but I hope to fix that as soon as I have some spare time :)

Very cool idea? Do you have a demo or write up about how it works? also would like to know how one can use it.

This is neat!

I was working on something similar recently: https://github.com/blevinstein/chess_assistant/blob/master/s...

I had been thinking about ways to analyze the graph of "threats", so I focused on which pieces were threatening which. I wanted to eventually extend this to also include which pieces were threatening which squares, but never got that far.

Nice. Hope it'd be good if you visualize how opponent's move could affect for the player in the other end.

It's not a very detailed explanation but the write-up is here: http://techn.ology.net/visualize-move-protection-and-threat-...

It's written as a server program in Perl, but it's relatively easy to install and run on your own computer:

> git clone https://github.com/ology/Chess-Inspector.git

> cd Chess-Inspector

> perl Makefile.PL

> make

> sudo make install

> perl bin/app.pl

Then open http://localhost:3000 in your web browser. Voila!

Thank you for your feedback!

I can definitely make the pieces larger. I will experiment...

The the tiny green border is definitely difficult to discern. I will think about how to display protection status more effectively. :)

Fixes made! 1. Increased piece size, and 2. colored the background of squares if protected, instead of increasing the border size. Thanks again. :)
