The key thing for winning with K+Q vs. K+R is to force a zugzwang by triangulation and force the rook to move away from the king. The position you're trying to achieve looks like this:
You have to actually have a winning position, there are some instances where the rook side can fortress.
I tend to just move the queen aimlessly and hope the opponent blunders a fork.
While Geller's clutching method does have its place in some instances you need to have deliberate coordination between your king and queen and sever communication between the rook and king.
I remember the sense of smugness when I learnt to mate with a knight and bishop.
It was totally dashed when I tried to do this against an engine! Luckily human players will hardly ever know how to hold this with the rook. Not that its possible to hold it and draw with accurate play but it can be made extremely difficult for the Q.
Theres a nice video of Danny rensch failing Q vs R against stockfish, illustrating my point.
I think this is only second in difficulty to 2 knights vs pawn. But at least that sounds tough. This, on the face of it seems like it should be quite simple.
I've played countless endgames of this type against a tablebase powered engine. I almost always solve them pretty efficiently but not on automatic! With a few seconds, even a few minutes on the clock, I'm fodder for the beast.
I think that there is some (somewhat) famous incident where a grandmaster was given a won position against a computer and nevertheless failed to win.

I am willing to believe that but they never tell you about the conditions on the clock!

The key thing for winning with K+Q vs. K+R is to force a zugzwang by triangulation and force the rook to move away from the king. The position you're trying to achieve looks like this:
Okay. But that's not really the main goal. The main goal is to force the separation of king and rook and get the rook. It's the best in any winning position. The second best way is to force a checkmating pattern, which is extremely difficult.

Isn't that almost exactly what Parnon said?

Okay but what your really trying to do is to take the rook by separating the king from the rook. The best way to win the position and checkmate the king is to take the rook without losing the queen. Unless you can checkmate him without winning the rook.
No, because it would have been stalemate. It's draw anyway (=perpetual), so it doesn't really matter though...: )
This is a difficult ending. Some grandmasters have failed to win it (GM Walter Browne even lost a bet).
With enough practice, you can master it.
When I was younger, I was able to win it against computers with tablebases (perfect defense).
Now, I simply can not (I guess I could re-practice it enough to master it again, but I am not trying, nor interested).
However, I do not worry. If it ever appears in one of my games, I am confident that my human opponent is most likely to defend sub-optimally, and I will be able to win.
Oh, as some people have already pointed out, it is not always won, there are some drawn positions. But it is mostly won.
Hi, I encountered a position where I had a queen and my opponent had a rook (I knew that there would be some way to force a win with the queen by forking the rook or making checkmate threats), we drew (kinda frustrating). Does anyone know how to win with a queen vs rook (it would be nice to use diagrams, puzzles, games/moves with analysis and explanatios)?
Thanks
