Message boards to the rescue...

On a couple of message boards, I asked what would be the best way to publish chess games in a Blog. On ChessNinja, Mike (aka Permanent Brain) had the following suggestions:

For diagrams, I use: http://chessup.net

You need to to get FEN strings from your program.

Edit: Meanwhile I saw you use a Mac. I must admit I am not
familiar at all with the Mac's World (except McDonalds ).

A Fritz user would configure Extras/Options/Clipboard -> Position: FEN
and then you can Edit/Copy/Copy Position and paste it for the ChessUp
diagram service (Enter FEN button).

Examples on a blog: http://computerschach.twoday.net/

For replayable games, it depends if you'd want the visitors to have Java
installed. Also, I don't know if your blog host allows Java applets on the blogs
pages. I use an very good compact online viewer which requires Java, in my homepage (chessgames.com uses it too): http://mychess.com/

This player reads PGN files and even zipped PGN files. Unlike other solutions, the HTML code is very small. Example: http://members.aon.at/computerschach/replay/stercomp.htm

Well, I'm going to take Mike's advice and use Chesspad to create the FEN string (standard notation for identifying a unique position on a chess board) for each diagram and then use Chessup.net to create the image.
