Can someone explain K+Q checkmate technique as if I'm a complete idiot?

You can just pretend your queen is a rook
Then your Queen does not need to get so close to the stinky losing king.

Be real careful not to stalemate.

I can't believe that there are people who teach this kind of nonsense. This "method" is the worst thing imaginable. An excellent way to blunder into a stalemate in the end. Just awful.
Not to mention that this method is worthless with a rook, while the real method works absolutely fine with a rook.
My respect for chesskid.com has just fallen off a cliff.

my respect for you, which was hanging on the cliff, has now fallen off it
what is the real method then?
memorising every single qk v k position and playing it like a dtm tablebase?
performing arcane wizardry?
and you mention a rook...
are you seriously pushing the queen up WITH the king?
and whats WRONG with this method
are you just a hater for hating sake?
are you just some purist who's like "you have to do it MY way"

Did you see that video? It promoted the highly artificial method of putting the queen a knight-move away form the king and force him to move, then again. This method has 3 disadvantages:
1. It takes 30 moves instead of 5-10.
2. The likelyhood of stalemate just went through the roof.
3. It is worthless with a rook.
As you want to learn to mate with a rook anyway, we can say that learning this method is a complete waste of time. Suggesting to kids that this is the way - it's just criminal.

yes i did watch the video (skimmed through it, but the method was clear and it was just artificially lengthened to 8 minutes for no reason)
whats the real method then?
seriously cant find it
you say 5 to 10...
are you memorising the dtm tablebase?
and memorising the dtm tablebase of kqk will definitely help in krk...
and besides...
taking longer is no issue unless youre playing no increment and in a time scramble (50 move rule is irrelevant as it was reset when entering the kqk anyway)
no, the likelihood of stalemate does not go through any roof, if you have half a brain
and whats your method which is useful with a rook
i cant find it

You need to restrict the king to one of the sides of the board, using the queen. The pattern shown here is unstoppable, and then you just deliver a simple checkmate. I’m not saying this is the best, or the only, way to deliver q&k mate. This is just the pattern that restricts the king.

You can't find a way to checkmate with a rook? I think this is a bit hard to believe.
Just to clarify: I'm not saying that that knight-move method is wrong. It can be used. Like when you want to go to the next town, you can start in the other direction, go around the whole globe, and arrive to the next town 40 000 kilometers later. It works, but it is ridiculously inefficient and impractical. Just like the method above.

I really don't think this should be taught. I think the exercise of working it out for yourself is far more valuable than the solution. If a player genuinely can't work it out for themselves then they can be given a simpler exercise to guide them towards finding the solution for themselves.

If people had to figure out how to do it by themselves, it would take too long.
Too long for what? This is right at the bottom of the stack of problems which you're going to need to solve and other people can only solve them for you for so long before you need to learn to teach yourself anyway.

Try the method set out in detail in this article. I’ve used it with hundreds of very young children.

Why all the trouble when one could just learn it from a source and move on their merry way?
Because learning the solution rather that how to solve it robs them of developing the problem solving skills.
Imagine if Mathematics was taught by giving people problems and solutions but students weren't encouraged to solve them on their own.

Why do you act like you know so much when you have a rapid rating of 1200?
Nice try. I've used the internet for too long, to engage with personal attacks.

I agree.
But people seem to be conditioned to be goal driven and in a rush to achieve those goals. Learning how to learn is something that may be missed in this hurry. Probably why there is very little carry over from one field to another for most people.
Checkmating a lone king does seem very similar to simple arithmetic to me. It may also help to understand the possible final mating positions and work backwards from them.
But what do I know?
I just blundered this AGAIN. I've tried learning it and it...just doesn't take. My brain finds the motions weird and doesn't comprehend them.
Can someone please explain as if I'm a mentally challenged baboon using its own poo for chess pieces?
