Queen v Rook – Getting to Philidor

Winning the Queen v Rook Ending - Part 2 getting to Philidor

This is the second part of Queen v Rook ending. In this article, we look how to get into the Philidor position. Once there, we know how to win from the first article.

This is our target position:

We are going to look at how to get there from any configuration of QvR (within reason!). It is possible to get to Philidor (or a Q & K v K ending) from most starting positions.

Journey

There is quite a journey in this ending!

Three things you will learn today

  1. It is possible to get to Philidor (or a Q & K v K ending) from most starts.
  2. On an open board, you can make progress but you need some inspiration!
  3. We can get from a second rank defence to Philidor.

Part 1 of 3 - Possible to get to Philidor from most positions

The Exceptions

More detail on the study position

Many players try to win by getting the king and queen to bully the king into submission in such a way but there's always an annoying pin/skewer to ruin the party.

Note in particular the stalemate after 1...Rc8+! 2. Kxc8 - this is a common defensive theme and most experienced players will know it. After a rook skewer, there really is no other outcome but a draw.

A similarly annoying position is below:

Annoyingly, black can just pelt white with checks until white gets fed up!

1...Ra2+ 2. Kb6 Rb2+ and white just alternates between the a file and b file knowing that any king move to the c file, results in a fatal skewer (e.g. 3. Kc6 Rc2+ 4. Kd7 Rxc8)

Summary of part 1

Aside from these annoying exceptions, it is pretty easy to believe that the queen and king should be stronger than the king and rook and we can execute the required technique.

Of course now we know these drawing techniques, we should try and avoid them at all costs (as well as rook skewers in general)!

The forceful bullying of the king by the king and queen can lead to an embarrassing stalemate.

Part 2 of 3 - Winning from an open board

For reference, we give two examples. One where the defender tries to make life hard for the attacker and another where there's an easy tactic - which saves you a lot of time.

Key Ideas

There are some themes known by the author through home analysis which were used in the creation of this analysis and worth remembering:
  1. The long line of pieces
  2. The king and queen's open dance

The long line of pieces

This is a line which frequently comes up when you try to play out this opening and it's a forced win.
Black to move (easier line)

Qf5 Kb8 3. Qe5 {and we follow the analysis above}

The king and queen's open dance

This works and is easy to remember.
Of course, this doesn't work at the edge of the board but works a charm in the middle of it. The rook soon runs out of checks, as the K+Q both cover d5, so ...Rc6+ 12. Kd5 leaves white ready to throw in Qg7+ and get to a second rank position.

Part 3 of 3 - Going from a second rank defence into the Philidor Position

In a technically won position, we are going to make sure the defender can only run into a Philidor position from any second rank defence.

[Event "Study of Queen v Rook"] [Site "Chess Toolkit (Author = KingAdmin)"] [Date "2017.02.16"] [Round ""] [White "A Queen"] [Black "S Castle"] [Result "1-0"] [ECO "N/A"] [Annotator "QTM"] [SetUp "1"] [FEN "2k5/4r3/1K6/3Q4/8/8/8/8"] [PlyCount "44"] [EventDate "2017.02.16"] [EventType "Endgame Study"] [EventCountry "GB"] 1. Qf5! {this is the key idea - all the rook moves in the following lines lead to a quick mate or a win of the rook, so the defender has to escort the king along the side of the board...} 1...Kd8 (1...Rd7 2. Kc6 Kd8 3. Qd7)(1...Kb8 2. Qf8 Re8 3. Qe8) 2. Kc6! {edging the king along, there's no useful rook checks} 2...Ke8 (2...Rc7 3. Kd6 {and there's no defence to a mate in 4! 3...Rc6 holds out the longest!} 3...Re7 (3...Rc1 4. Qf8)(3...Rc6 4.Kc6 Ke7 5. Kc7 Ke8 6. Kd6 Kd8 7. Qf8 {phew!}) 4. Qf6 Ke8 5. Qe7) 3. Kd6 {exactly the same ideas!} 3...Rg7 {best chance - other moves lose faster!} (3...Rd7 4. Qd7 )(3...Ra7 {3...Rb7 is the same}4. Qh5 Kf8 (4...Kd8 5. Qh8) 5. Qh8 Kf7 6. Qh7 Kf6 7. Qa7) 4. Qh5 {forcing the king along once more} 4...Kf8 (4...Kd8 5. Qh8 Rg8 6. Qg8)(4...Rf7 5. Ke6 Kd8 6. Qf7) 5. Ke6 {now the rook is in paralysis - if it moves off the 7th, Qf7# is a nasty threat; otherwise, if it moves off the g file, Qh8# is also a nuisance.} 5...Kg8 6. Kf6 {recognise this position? It's Philidor - also with the defender to move!}

From that starting 2nd rank position, we reached Philidor in 6 moves!

Summary of part 3

  • We are aiming for the Philidor Position which we know how to win from the other lesson.
  • We can push the king along until he has to go into the Philidor from a point!
  • It's important to know why other moves don't work!
  • Summary and Recommended Next Reading

    • The technique to win this ending is to go from an open position to a third rank defence, then a second rank defence to a Philidor position.
    • We should always be on the look-out for a queen fork, winning the rook for free and be on our guard for a rook skewer!
    • This is not an easy ending and time is needed to learn the steps. One wrong move can cost us a lot of time!
    • It is possible to win.
