Most chess teachers say one of the methods to improve your game is to
look over your games, especially your tournament games, and look for
where you made mistakes. Part of this learning may be solely in the
finding. However, not everyone has a grandmaster chess teacher looking
over their games, who will point out blunders and missed opportunities
that the student has missed.
Which is where my program comes in,
which I call "Blunder". It is still in beta as everything has not been
fully automated yet, but I have it working well enough for me. It
definitely can be more automated, some
of these steps are unnecessary. It is working though.
When I wrote this program suite, I assumed there must be a simple,
public PHP program out there that would locally display chess board web
pages when given a FEN input. I was surprised to find out there is not
(or at least I couldn't find it). There were some contenders, but
nothing simple and public that did what I needed, or even close to it.
So I wrote displayfen.php, which is fed a FEN and pops out a chess board
in nice 100x100 pixel square format that fits nicely on my browser. I
also converted some GFDL Wikipedia Commons SVG chess pieces to PNG
format and included them. If this is all you need, just grab the
displayfen function from the displayfen.php file.
Also: Related to this, I began writing some programs to train me for
openings. However, it is a little more difficult than the Blunder
program for a number of reasons - there are 20 possible opening moves
for white, and 20 possible counters by black, thus, in the first move we
already have 400 possiblities. I have the beginnings of it if anyone is
