[theborakompanioni]

Is your feature request related to a problem? Please describe.
As an Amethyst user who is a chess player, I would like to view Chess (PGN) messages as chess boards, so that I can interact with and review Chess games.

Describe the solution you'd like
Display Chess (PGN) messages as a chess board.

Bounty (in Bitcoin sats) offered for the implementation
Since this is an invaluable feature: 22mio bitcoin.
Okay, just kidding. As a poor Open Source Developer, I can throw 21k sats at anyone getting this merged. 🧡

Additional context

In order for nostr-protocol/nips#1094 to be approved, it needs to be implemented in two clients.
Would Amethyst be interested in displaying kind := 64 as chess board in the interface?

NIP-64: https://github.com/theborakompanioni/nips/blob/nip-64/64.md

The spec is quite simple and straightforward–so it should be rather easy.
It would need to include a dependency on a library capable of drawing chess boards.
Please, let me know 🙏
