Basic chess endgames every beginner should know

In the opening and middlegame both sides have plenty of material, so a small mistake often gets lost in the noise. The endgame is different. With only a few pieces left, every move matters and every extra pawn can decide the result. A single passed pawn that reaches the far side of the board becomes a new queen, and that is usually game over.

The good news is that endgames are the most learnable part of chess. Openings have endless variations and middlegames depend on judgment, but the basic endgames are closer to a recipe. The same techniques win the same positions every time. Learn the few that come up most, and you will start finishing the games you used to let slip into draws.

This is the most common winning endgame, because a queen is the prize for promoting a pawn. The method is simple once you see it: the queen herds the enemy king to the edge of the board, and your own king walks up to deliver the mate. The queen alone cannot finish the job, you need the king to help.

The reliable trick is the knight’s-move method. Place your queen a knight’s move away from the enemy king (the L-shape a knight travels). From there the queen takes away a whole block of squares, and as the enemy king moves, you keep answering with another knight’s-move jump that stays close but never adjacent. Step by step this walls the king onto a back rank or a side file.

Once the enemy king is pinned to the edge, bring your own king up to stand two ranks (or files) away, directly facing the trapped king. Then the queen delivers checkmate on the edge, with your king guarding the escape squares. The one thing to watch for is stalemate. If the enemy king has no legal move and is not in check, the game is a draw. So as you close in, always leave the trapped king at least one free square until the move you actually deliver mate. If you ever crowd it so tightly that it cannot move and is not in check, you have thrown the win away.

A rook cannot cover as many squares as a queen, so this mate takes a little more care, but it is just as forced. The standard approach is called the box method (some books call it the staircase). The idea: use the rook to draw a line the enemy king cannot cross, shrinking the box it lives in one rank at a time, until the box collapses on the edge.

Here is the procedure step by step:

1. Cut the king off with the rook. Put your rook on a rank or file so the enemy king is boxed into one side of the board and cannot step over that line.
2. March your king toward the enemy king. The rook holds the wall while your king walks up to confront the enemy king face to face.
3. Take the opposition, then shrink the box. Get your king directly opposite the enemy king with one square between them. When the enemy king is forced to step sideways, use the rook to push the wall one rank closer, making the box smaller.
4. Repeat until the edge. Keep alternating: confront with the king, shrink with the rook. Eventually the enemy king is squeezed onto the last rank, and the rook delivers checkmate along that edge while your king guards the escape.

If the enemy king ever runs at your rook, just slide the rook far down the same line to keep it safe, then resume. The same stalemate warning applies: do not box the king so tightly that it has no move before you are ready to mate.

The opposition is the single most important idea in king and pawn endgames, and most beginners have never heard of it. You have the opposition when the two kings stand on the same rank, file, or diagonal with exactly one square between them, and it is your opponent’s turn to move. Because a king cannot move next to the other king, whoever is forced to move first has to give ground.

That sounds like a small thing, but it decides whether a lone pawn promotes. Picture a king and pawn against a lone king. If the defending king is in front of the pawn, the attacker can only break through by seizing the opposition and forcing the defender to step aside, which opens a path for the attacking king to escort the pawn home.

The rule of thumb: to win, get your king in front of your pawn with the opposition. If your king reaches the sixth rank ahead of the pawn (the third rank if you are defending from the other side) with the opposition, the pawn will promote. If the defender holds the opposition and keeps the attacking king back, the position is often a draw. This is also why one of the trickiest cases, a rook pawn (the a or h file) plus a wrongly placed king, is a known draw even when you are up a pawn: the defending king reaches the corner and cannot be pried out.

Sometimes a pawn is racing to promote and the only question is whether the enemy king can catch it. You do not need to count moves one by one. There is a shortcut called the square of the pawn, and it answers the question at a glance.

Imagine a square whose top edge runs from the pawn to its promotion square, with sides of equal length stretching toward the enemy king. If the defending king is inside that square (or can step into it on its move), it catches the pawn. If the king is outside the square and it is the pawn’s turn to move, the pawn promotes and the king cannot stop it.

One detail saves you from errors: a pawn still on its starting rank may advance two squares, so draw the square as if the pawn were already one step forward. Get this picture in your head and you can judge a pawn race instantly, without calculating a long line of king moves.

A passed pawn is a pawn with no enemy pawns ahead of it on its own file or the two files beside it, so no pawn can block it or capture it on the way up. Nothing but an enemy piece can stop it from promoting, and in the endgame, when pieces are scarce, a passed pawn is often unstoppable. This is why trading down into an endgame while you hold a passed pawn is so strong: you are heading for a position where your extra pawn becomes a queen.

A passed pawn is most dangerous when it is far advanced and when your own king or pieces can support its march. A common winning plan in a level-looking endgame is to create a passed pawn, push it, and force the enemy pieces to tie themselves down stopping it. While they babysit your pawn on one side, your king goes hunting on the other. The threat of promotion does the work even when the pawn never actually queens.

Beyond the specific positions above, a few habits separate players who win endgames from those who fumble them. Each one is easy to remember and pays off in almost every game.

• Activate your king.In the opening the king hides, but in the endgame there are too few pieces left to checkmate it, so it becomes a fighting piece. March it toward the center and the action. An active king supports your pawns, attacks the enemy’s, and is often worth a pawn on its own.
• Push your passed pawns. When you have a passed pawn, advance it. Every step closer to promotion forces the opponent to react and ties their pieces down.
• Put rooks behind passed pawns.A rook belongs behind a passed pawn, whether it is your pawn or your opponent’s. Behind your own pawn the rook supports the advance and keeps gaining scope as the pawn moves up. Behind the enemy’s pawn it stops the advance while staying flexible. A rook stuck in front of a passed pawn just gets in the way.
• Do not rush, and watch for stalemate. Endgames reward patience. When you are winning, double-check that the enemy king always has a legal move until the instant you deliver mate, so you never stumble into a stalemate draw with a winning position.

Reading about an endgame and executing it under your own hand are two different things. The two basic mates in particular need repetition: the first time you try to corner a king with a queen you will probably stalemate it once, and that is exactly how you learn to avoid it. The technique sticks only after you have done it yourself a few times.

The Melio chess puzzles are a clean place to drill. Set up the winning side, practice walking the enemy king to the edge, and repeat the king and rook box until the staircase feels obvious. Once the queen mate and the rook mate are automatic, and you can read the opposition and the square of the pawn on sight, you will be finishing games that you used to let slip away.
