Description
Chessgame Shizzle is a nice way to integrate chessgames into your WordPress website. Ideal for chess clubs, your chess blog, or any chess related website.
Editors and guests alike can add chessgames in PGN format through a frontend form. All chessgames are available in a custom post type as a single post with an archive list and taxonomies, it couldn’t be more simple. Included widgets give you many ways to display your chessgames.
Current features include:
- List view and single view for chessgames as a WordPress post.
- Easy to use form on the frontend to add a chessgame.
- Simple and clean admin interface that integrates seamlessly into WordPress admin.
- JavaScript enabled game viewer (pgn4web).
- Several widgets to display latest game, featured game or a list of recent games.
- Tactics Lessons, useful for trainers and students.
- Moderation, so that you can check a chessgame before it is visible.
- Subscribing to notifications.
- Board themes and Piece themes.
- Anti-spam features with Nonce, Honeypot and Form Timeout for upload form.
- Import and Export from and to a PGN file.
- Generate (featured) images from a chess position.
- Localization. Own languages can be added very easily through GlotPress.
… and all that integrated in the stylish WordPress look.
Translations
Translations can be added very easily through GlotPress.
You can start translating strings there for your locale. They need to be validated though, so if there’s no validator yet, and you want to apply for being validator, please post it on the support forum. I will make a request on make/polyglots to have you added as validator for this plugin/locale.

FAQ
-
What is PGN notation and how do I write it?
-
PGN notation is a way to write the moves of a chessgame, plus some metadata, like names of the players, etc.
On Wikipedia there is more general information. -
I added a chessgame, but when viewing I get a 404 error.
-
Please go to Dashboard > Settings > Permalinks and hit ‘Save’ twice. That should flush your permalinks and make it work.
-
Where is my index page with the archive of chessgames?
-
You can browse to /chessgame and you will see the archive page. The template used for this is archive.php.
-
Which shortcodes are available?
-
- ‘[chessgame_shizzle_form]’ for the upload form.
- ‘[chessgame_shizzle_simple_list]’ for a simple list with pagination.
- ‘[chessgame_shizzle_game postid=”536″]’ to show a single game that was published in the chessgames post type.
- ‘[chessgame_shizzle_game_extended postid=”536″]’ to show a single game that was published in the chessgames post type.
- ‘[chessgame_shizzle_lessons]’ for lessons on the frontend.
In case you read this on wordpress.org, the quotes are supposed to be standard double quotes, no backticks.
-
I only want to show games from a category or tag.
-
You can use a shortcode parameter for showing games only from certain categories or tags:
[chessgame_shizzle_simple_list category="213,212" tag="345,355"]In case you read this on wordpress.org, the quotes are supposed to be standard double quotes, no backticks.
-
What about Spam?
-
By default this plugin uses:
- Nonce: Will verify if you really loaded the page with the form first, before posting a chessgame. Spambots will just submit the form without having a Nonce.
- Honeypot feature: Hidden input field that only spambots would fill in.
- Form Timeout: Check if the form has been submitted too fast.
New submitted chessgames will be set as pending, waiting to be moderated. When someone adds a chessgame that is considered spam, it will not be accepted and the user will get a message on the frontend form.
