Obsidian Chess Study

A chess study helper and PGN viewer/editor for Obsidian.

With this plugin, you can either import PGNs or simply start a fresh new game. It allows you to add comments and arrows for each move, which will be persisted within a JSON File in your vault. Although it is not a full analysis board, it serves as a valuable tool to support your chess notetaking in Obsidian.

Motivation

I love Obsidian and its tools, but managing screenshots of chess positions is getting out of hand and is also annoying to update. It would be great to have a PGN Viewer similar to the ones offered by lichess.org or chess.com within Obsidian. It should allow us to effortlessly view PGNs, add arrows and comments, while also persisting them inside the Obsidian vault. The currently existing alternatives primarily focus on visualizing FEN snapshots, which is why this side project started.

Installation

Once you have disabled Safe Mode, you can find third-party plugins by navigating to Settings > Community Plugins > Browse and search for "Chess Study". Once you have installed the plugin, you can access it under Settings > Community Plugins. Please note that you must enable the plugin to use it. You can also unsintall the plugin from there.

Usage

To start, position your cursor where you want to place the PGN viewer/editor within your note. Execute the Obsidian command Chess Study: Insert PGN-Editor at cursor position.

This action will trigger a modal window, where you have the option to paste your PGN or leave it empty for a fresh new game. Here is what it will look like:

Once you click Submit, Obsidian Chess Study will parse the PGN, generate a new JSON file in your vault located at .obsidian/plugins/obsidian-chess-study/storage/{id}.json, and insert a chessStudy codeblock at the cursor's position. Here's an example of the chessStudy codeblock:

After that the PGN viewer/editor will render and you are good to go:
