Awesome, thanks! Tho no need to hurry yourself over it, we'll both probably be dead and gone before I ever manage to finish a game that I'll be able to use it in, lol. And yeah -- a lot of games end before that rule ever has a chance to come into play, so it's an easy one to miss... But on longer games, it becomes HUGELY important; Since it's actually possible to have more than one Queen on the board, players have a lot of incentive to aggressively pursue that course of action... Although I personally never owned a physical chess set that had extra pieces for that purpose, so even I didn't realize that was allowed in the actual rules!
