Understood.
BUT. The internet or power ALWAYS disconnects when it's the turn of the player experiencing the disconnection. And if I save the game during their turn, how can I then start the game from that save?

If you don't trust your opponent, pause the game, contact the host or judges, share the saves and passwords, and explain all the details. I've already written about this.

If you trust them, load the save when the opponent re-plays their entire turn. In situations where someone sees that a turn will be long or a disconnect is anticipated, it is recommended to manually make several saves during the turn, so as not to have to re-play long turns.
