Hello, chess.commers!

I've read about it a little bit, but I'm noe quite certain how to win a K+Q vs K+R endgame (without pawns), where you have the queen. I know there is a certain method. Can anyone teach me?

Thanks, Freecat!

It's complicated, I would advise picking a different ending to add to your repertoire before tackling this one!

against a properly set up defence (and not when black is already lost like in the video) it's technically almost impossible for a human to win against best play (engine) but in a practical situation a bit of tactical sharpness should allow you to check and check until your opponent makes a mistake.

So when played perfectly by both sides, it's a draw?

its a win, except in rare circumstances its a draw...

Man  i saw grandmaster endgames you have no idea what they see, its phenomenal. You really wonder how those guys can ever lose a game.

No, played perfectly by both side the Queen wins within 31 moves.

However the method to crack the so called third-rank defence is counterintuitive and hard to learn. It would take a ton of time and effort for us to learn to win this against an engine, and it's not that useful to practice because in a practical situation I think we can count on a blunder by our human opponent.
