Made a free helper for the Grandmaster trophy (Checkers, Fanorona & Nine Men's Morris)
TL;DR: I got annoyed, vibed a web app, and now it shows you how to beat the board games. PC/mobile/tablet, works offline, no ads.

I was trying to 100% the game and followed a few videos showing how to win the board games, but then I realized they aren't "set games." Every match is different. So I figured I'd just vibe a web app, and here it is: Boardmaster.
It's just a website, but it's built as a Progressive Web App (PWA), so if you want you can install it like an app for easier access and offline use.
Just choose who starts. Then, whenever your opponent makes a move, copy that move into the app and it'll show you the best move to make next. I recommend using the 1-star opponents (coordinates included in the app).
It works against any opponent, it's just faster against the 1-stars. There also seems to be a bug in AC where finishing a 3-star game can freeze the game and force a restart. That might just be my copy, but I figured I'd mention it. If you do play the 3-stars, the game may ask if you want to call it a draw. Just keep saying "No" a few times and you'll eventually finish the match.
Also, just a little tip. The Fanorona AI is fast. Press "Play this move" before making your move in-game so you're already watching the game when the AI responds.
I built this as a little side project, so I'll keep an eye on it. If you find any bugs or have suggestions, let me know. I can't promise I'll fix everything, but I'll do my best.
