If K+Q is white, K+R is black & black to move. What will be the final result of the game?

White should win but it's very difficult, much harder than K+B+N v K.

Black to play. Black wins.

It depends. Generally a queen can fork both king and rook, but in this position Black is clearly winning.

The K+Q side has to avoid a stalemate, for instance if black is to move



he simply plays Rd6+ (QxR = stalemate).

Apart from that, the queenside should win in 20 - 30 moves. Gradually moving the kings closer to each other (the rookside king close to the border, later on to the corner). With mating threats, force the rook to move away from his king, and then, still with mating threats, find double attacks on king and rook. Given the theoretical maximum number of moves, you can afford a few tries (but not allow stalemate) and still win in time. It is not very difficult.

Here is a setup game where I guided (through messages) my opponent towards the win.

in general, it just depends on the position of the white K and Q, compared to the black R, possibly his king also

Well, that was nice of you 😛

Yes, white can always win Q vs R except in the rare instances mentioned. But it's very difficult. GM Svindler played a game in which he had a lone queen against his opponent's lone rook and was unable to win within 50 moves and the game was drawn.
