I remember liking that video the first time I saw it. If I remember correctly though, the creator of that video had quite a few sexual abuse allegations against him and I wasn’t really into it after that came to light.

Yep that’s the original!

There actually is an “official” remake also published by Interplay but it’s unfortunately not very good and I really can’t recommend it at its current price: https://store.steampowered.com/app/200150/Battle_Chess_Game_of_Kings

This seems really powerful; I’m curious, how helpful were its suggestions?

I remembered seeing it in an Ashens video! Here’s a link: YouTube / Piped It’s only the first two thirds of the video, the rest is unrelated.
