White winsKing and Pawn vs King
For sub-1000 ELO players
King and Pawn vs King is a win for the stronger side when the king gets in front of the pawn. The key technique is called opposition: placing your king two squares directly in front of the opponent's king with one empty square between them. Whoever has to move loses the opposition and must step aside. Stockfish 17 at depth 25 confirms this position is a forced win for White. Most sub-1000 players push the pawn first and lose the win because the defending king blocks promotion.

Key Moves
The moves that decide the game
Ke3Ke1d4Kd1Kf3The king leads the pawn up the board. Never let the pawn outrun the king.
What Happens With Perfect Play
Get your king in front of the pawn before pushing it. The king leads, the pawn follows.
Stockfish confirms the starting position is a forced win for White (+M19).
This technique works for b, c, d, e, f, and g pawns. Rook pawns (a and h files) have special drawing cases -- see the draw exceptions below.
3 Mistakes Sub-1000 Players Make
These are the patterns we see in endgames below 1000 ELO. Fix these and you will stop drawing won games.
Pushing the pawn too early
Beginners push the pawn on the first move because it looks like progress. But without the king in front, the defending king steps in front of the pawn and blocks promotion. The pawn cannot push a king out of the way by itself.
Ke3After d3, Black plays Kd1 or Ke2 and stays close to the pawn. White's king has to waste moves catching up, and Black gets time to block. With correct defense, the game can end in a draw.
Losing the opposition
White's king wanders to the wrong side and Black's king steps directly in front of the pawn. Once the defending king has the opposition (standing directly in front of the enemy king with one square between you), the attacker cannot make progress.
Ke6Black plays Kd8 and holds the opposition (standing directly in front of the enemy king with one square between you). White cannot advance the king without letting Black back in front of the pawn. The game repeats and draws.
Not knowing the rook pawn draw
Beginners do not know that a-file and h-file pawns almost always draw, even with the king in front. They spend 50 moves trying to promote a rook pawn that will never queen, running down the clock and missing chances to win with a different pawn.
Play for a different pawnThe defending king sits in the corner (a8 or h8). The attacking king cannot push it out without creating stalemate. The game is drawn no matter how well you play.
Key Squares to Know
These are the squares that decide the game. Get your king to these squares and the pawn promotes.
d6Key squareIf White's king reaches d6 with the pawn behind it, the pawn will promote. d6 is the most important target square for the White king in this endgame.
d8Promotion squareThe pawn must reach d8 to become a queen. White's king must escort the pawn here while keeping the Black king away.
e6Opposition squareWhen the White king reaches e6 with the Black king on e8, White has the opposition (standing directly in front of the enemy king with one square between you). Black must move first and step aside, letting the pawn through.
f6Outflanking squareWhen the Black king blocks on d7, White's king goes to f6 to outflank. This forces the Black king to retreat and gives White access to e6.
When to Accept a Draw
Not every position is a win. Know these exceptions so you stop wasting moves on positions that cannot be won.
Rook pawn exception
King and Rook Pawn (a-pawn or h-pawn) vs King is almost always a draw. The defending king goes to the corner on the promotion square side (a8 or h8). The attacking king cannot force the defending king out of the corner without creating stalemate. This is the single most important exception to learn. If you have only a rook pawn left, trade it for a chance to win elsewhere. Do not spend 40 moves pushing a rook pawn into a known draw.
King too far from the pawn
If the defending king is already on the promotion square (d8) and the attacking king is far away (like h1), the win still exists in theory but requires perfect technique over many moves. At sub-1000 level, these games often draw because the attacking side makes a mistake along the way. Practice getting your king to the center early in the endgame so this situation does not happen.
Common Questions
+How do you win a king and pawn vs king endgame?
Get your king in front of the pawn before you push it, then escort the pawn up the board. The king leads, the pawn follows. Most beginners push the pawn first and lose the win because the defending king walks straight to the promotion square and blocks. With your king ahead and the opposition (your king two squares directly facing the enemy king with one empty square between them), the pawn promotes in under 19 moves. Stockfish 17 at depth 25 confirms the standard position is a forced win.
+What is the opposition in chess?
The opposition is when the two kings face each other directly on the same file or rank with exactly one empty square between them. Whoever has to move loses the opposition: their king must step aside. In King and Pawn vs King, the attacking side wants the opposition because it forces the defending king out of the way of the pawn.
+Why does my pawn keep getting blocked in the endgame?
Because you pushed the pawn before bringing your king. A lone pawn can't push a king out of the way. The defending king walks straight to the promotion square and sits there. Always move the king to the front of the pawn first. Then advance them together.
+Can you always win king and pawn vs king?
Almost always. The exception is rook pawns (a-file or h-file). Against best defense, king and rook pawn vs king is a draw: the defending king sits in the corner and the attacking side can't push it out without causing stalemate. For every other pawn (b through g), it's a win when your king reaches the 6th rank in front of the pawn with the opposition.
+How many moves does it take to promote a pawn against a king?
From the standard starting position with your king and pawn well-placed, promotion takes 8 to 19 moves with optimal play. The 50-move rule (FIDE Article 9.3) gives huge margin even if you play imperfectly. Worst case is a long pawn race where the king is far from the pawn: that can still be a win but requires precise opposition play.
+What is the easiest pawn endgame to learn first?
King and Pawn vs King with a center pawn (d-pawn or e-pawn) and your king already in front of the pawn. Set up White king d4, pawn d2, Black king d8 in your trainer and play it 10 times from the winning side. Once you feel the opposition shift, every other pawn endgame becomes easier.
