King and Queen vs. King and Rook

omglolbbqpizza

Today I played a game with a King and Queen vs. King and Rook. I'll show you an example of a King Queen vs. King Rook. Normally it'll be a draw until someone blunders, but I won on this game with a player.

The blunder that White did was moving his King. When my King and Queen was lined up, he should have pinned it or tried to do perputual check, making it a draw.

Actually, Queen vs Rook is a general win, but is extremely difficult against best play.

King and queen against king and rook is a win for the queen, unless it starts from a position where there is perpetual check, stalemate, or if the rook can capture the queen.

12. Rg3+ Kf2 13. Rg1 is this going to be draw?

Maybe not...

Actually, the best defense in this ending (White can still win, but it is extremely difficult) is called the third rank defense. The rook is placed on a rank or file two from the edge. The king is on the two ranks/files closer to the edge of which the rook is two ranks/files away from, with the attacking king on the other side. The point is that the rook is cutting the attacking king off from the only rank/file from which it can initiate mate threats.

12. Rg3+ Kf2 13. Rg7 is this going to be a draw?

Lolly, Shen, and Phlidor Defense can be used here.

No, a mate is always possible unless the side with a rook can stalemate or win the queen.

12. Rg3+ Kf2?? would be a big blunder as white could draw - Rf3+.  White skewers the king and queen, so if the king moves away, white takes the queen.  If black takes the rook with his king, it's stalemate.

This is what you want to aim for as white:

I have tried for some time now, to understand this endgame. Once in the final position (philidor position) it is relatively easy. There is a great video that explains how to proceed. http://youtu.be/cdxeYhm-2B0

However, my greatest concern is how to force my opponent into this position. When I try, I usually find myself locked up in a fourth rank defense. Anyone have a "recipe" for how to break down the resistance?

It is the philidor position. White is able to win if he knows the technique. Otherwise he may blunder and draw

You need to be a great chess player to win queen and king with queen and rook. The possibility of getting forked is too high

There was a game where Svidler tried for over 100 moves to prevail against Gelfand who had the rook. This ending has a history involving Ken Thompson and Walter Browne. The clock can play a very big role in this ending in practice! and then there is this https://www.youtube.com/watch?v=7EMcKsH9hMI&t=111s
