Pawn endgames

Endgame course · 4 lessons · 6 drills

Where every middlegame plan is finally audited.

Trade everything off and the truth comes out: one tempo, one square, one king a step too slow. This course teaches the four mechanisms that settle king and pawn endings, from the opposition to the Réti manoeuvre, each one from the writer who set it down.

The first lesson, King versus king, one tempo apart. You play White.

Nothing to review. Learn the next drill.

Before the moves: the big ideas

  • The king in front, one square to spare

    Capablanca's essential rule for the single pawn: the king belongs in front of its pawn with at least one intervening square, and if the defending king stands directly in front of the pawn the game cannot be won. Half of this course is that sentence played out from both sides.

  • Opposition is a means, key squares are the end

    Averbakh's correction to a century of rote teaching: opposition is a means to an end, and the end is penetration to a key square. If the king can reach one without the opposition, take the shorter road.

  • Count the square before you run

    Draw the square from the pawn to its queening rank: a defending king inside it catches the runner, one outside it loses the race. Fishbein supplies the second layer the bare rule misses, an attacking king that shoulders the defender out even after it enters the square.

  • One king, two errands

    Réti's 1921 study rescued a hopeless-looking draw by giving the king two jobs per move: chase the enemy runner and escort its own. Gurvich called the theme the hunt of two hares, and it decides real games, not just studies.

The lessons, method then drills

Read the method first; the drills put its steps to work.

The opposition

King versus king, one tempo apart

Two kings face each other and neither wants to move: whoever must step aside lets the other through. Capablanca gives the parity rule: with an even number of squares between the kings, the mover seizes the opposition; with an odd number, the player who has moved last has it. Edward Lasker adds the defensive half, a king that commands the queening square and takes the first-rank opposition the moment the pawn touches its sixth rank cannot lose.

  1. Count the squares between the kings on their shared line. Even gap: taking a step seizes the opposition. Odd gap: whoever moved last already holds it.
  2. Holding it, advance only when the enemy king gives ground; step diagonally to keep the count in your favour.
  3. Use it for something: the opposition is a means, and the end is reaching a key square beside the pawns.
  4. Defending, plant the king on the queening square and wait for the pawn to reach its sixth: then take the opposition on the first rank and the position is stalemate or repetition.

King and pawn: the escort

K+P vs K

One pawn wins or draws on a single condition, and Capablanca states it before showing either side: the king belongs in front of its pawn with at least one intervening square, and a defending king planted directly in front of the pawn kills the win. His two worked examples are this lesson's two drills, the same ending from both chairs.

  1. Winning, walk the king ahead of the pawn and keep it ahead; the pawn advances only when its own safety demands it.
  2. Take every square the defender concedes; the escort gains ground on zigzags, not on the pawn's file alone.
  3. At the sixth rank, mind the one losing move: advancing the pawn to the sixth with check hands over the draw.
  4. Defending, stand directly in front of the pawn; forced away, go in front of the enemy king instead and hold the opposition.

The rule of the square

King versus passed pawn

A runner with no escort is caught by geometry: draw the square from the pawn to its queening rank, and a defending king inside it arrives in time. Fishbein's demonstration supplies the second layer the bare rule misses, because entering the square is not the same as crossing it when the attacking king stands in the road.

  1. Draw the square in your head: pawn to queening square on one side, the same distance along the rank on the other.
  2. Defender inside the square catches the pawn; outside it, the race is already lost. Check before you commit the king.
  3. Attacking, do not race at all if your king can block: step into the defender's path so every escort move also shoulders it away.
  4. Only when the road is clear does the pawn run.

The Réti manoeuvre

K+P vs K+P, king outside the square

The most famous endgame study there is: White's king sits outside the square of the black pawn with its own runner blockaded, and every count says lost. Réti published the rescue in 1921, a king walk on the one diagonal where each step does two jobs with every step counted. Black must spend two tempi on White's pawn, and those are exactly the two tempi the king needs to reach the square of Black's.

  1. Refuse the straight chase; a king outside the square never catches the runner by running.
  2. Walk the diagonal that leans on both errands at once: toward your own pawn's escort square and toward the enemy runner's square.
  3. The defender must break off to deal with your pawn; each move it spends there is a tempo you gain on the chase.
  4. Arrive at the fork square, then take whichever errand the defender abandoned.
