I'm glad someone takes the time to explain this game. I have seen it a lot being played in anime and manga but obviously I can't follow what's going on when it happens because they don't take the time to explain it.
Your explanation is pretty thorough, good job :D.
Congratulations on your curie vote.
I've seen it in some anime too (I've read some shogi manga too)obviosly gets way more interesting when you know how to play it, even general is better than nothing. I'll probably do mahjong next(there's an old classic anime called akagi, and a pretty modern one called saki)rules for that are really insane even compared to this, but I'm actually decent at it.
