How to checkmate with a queen, a rook or two rooks
Two rooks, king and queen, king and rook against a lone king: these are the basic checkmates, and every player needs to give them without thinking. Here is the method for each one, in steps, with the stalemate traps that turn a won game into a draw.
Why the basic checkmates matter
Sooner or later you reach a position where your opponent has only the king left and you have a queen or a rook more. The game is won, but it is not over. If you do not know how to finish, the clock runs down, a careless move gives stalemate, or the fifty-move rule lets your opponent claim a draw: fifty moves by each side without a capture or a pawn move.
The three methods share one idea. With this material, the lone king is mated on the edge of the board, so you push it there, one rank or one file at a time, and you never let it back towards the centre. Two rooks can do this on their own. The queen and the single rook need the help of their king.
Two rooks: the ladder mate
Start with the easiest. One rook cuts the enemy king off along a rank, the other gives check on the next rank, and they take turns, climbing like the rungs of a ladder until the king reaches the edge. A queen and a rook mate the same way.
The rook on g4 guards the fourth rank, so 1.Rh5+ sends the king up: 1…Kd6. Now the other rook climbs past it: 2.Rg6+ Ke7 3.Rh7+. Each rook in turn gives check one rank higher, then stays there as a wall while the other one climbs.
Watch what Black does: the king walks towards the rooks. After 3…Kf8 it stands next to g8, so 4.Rg8+ would only lose a rook to 4…Kxg8. Do not give the check yet: move the rook on h7 to the far side of the board, along its rank, out of the king’s reach. After 4.Ra7 it still holds the seventh rank, Black’s only move is 4…Ke8, the king no longer guards g8, and 5.Rg8#.
When the lone king comes close to your rooks, do not try to protect them. Move one of them to the other side of the board along its rank: it keeps its wall, and the king can no longer reach it.
King and queen against king
The queen is strong enough to drive the king to the edge alone, but she cannot give mate without her own king. The method has three steps.
- Shrink the box. The queen cuts the enemy king off on a rank and a file at once. A simple way to do it: put her a knight’s jump away from the king, and each time it moves, follow it at the same distance. The box of squares it can use gets smaller with every move.
- Stop when the king is on the edge. Once it is stuck on the last rank or file, leave the queen where she is and bring your own king, step by step.
- Mate with both. The queen gives mate on a square next to the enemy king, protected by your king, or along the edge while your king covers the squares in front.
The king is in the box and cannot get out, so the queen has done her job. The tempting move is 1.Qc7??, a knight’s jump from a8, the very trick that drove the king there. It takes b8 away as well: Black has no legal move and is not in check. That is stalemate, and the game is a draw.
Bring the king instead: 1.Kc5 Kb8 2.Kc6 Ka8 3.Qb7#. The queen can stand next to the black king because your king protects her. Stockfish confirms that it is mate in three, and the queen did not need to move until the last move.
King and rook against king: the box
The rook mate takes longer, because a rook cannot cover the squares around the king as a queen does. Your king does more of the work, and two ideas help it: the opposition, when the two kings face each other with one square between them, and the waiting move. The steps:
- Make a box with the rook. Put it on a file or a rank that shuts the enemy king into the smaller part of the board, far enough away that the king cannot attack it.
- Bring your king towards the enemy king, so that the two kings come into opposition.
- Shrink the box. When the kings are in opposition, a rook check pushes the enemy king back one rank or one file. When they are not, bring your king closer without letting the enemy king out.
- Use a waiting move. If the enemy king steps away from the opposition, move the rook along its line: the box stays shut, and Black must move again.
Your king covers b6 and c6, so the rook can check: 1.Rd7+. Black’s most stubborn reply is 1…Kc8, on the back rank, attacking the rook. Your king comes to protect it, in opposition: 2.Kc6. Black’s only move is 2…Kb8, out of the opposition, and your king follows: 3.Kb6.
Now 3…Kc8 steps aside again and attacks the rook. This is the moment for the waiting move: 4.Rd4 goes back down the d-file, out of reach, and the box stays shut. Black’s only move is 4…Kb8, in front of your king, and 5.Rd8# mates along the back rank.
When the enemy king will not step in front of yours, do not chase it with checks. Pass the move with the rook, and let the king come to you.
Stalemate: the traps to avoid
Stalemate is a draw, half a point instead of a whole one. In these endings the danger comes in the last few moves, when the king is on the edge or in the corner and has few squares left. Three habits keep you safe:
- Count the king’s moves. Before each move near the edge, check that the lone king will still have a legal move, or be in check.
- Stop following with the queen. The knight’s jump drives the king to the edge. Once it is there, leave it its squares and bring your king.
- Let the king move. A waiting move works because the lone king still has a square to go to, the one in front of your king.
How to practise the basic checkmates
Set up each of the three positions on a board and play them out until you can mate without hesitating. Then start from new positions, with the lone king in the centre and your pieces anywhere, and time yourself: in a real game, with a few minutes on the clock, the method has to be automatic. Play the other side too, as a stubborn opponent would: walk towards the rooks and step away from the opposition.
These mates come at the end of the road. Before you can give them, you have to win the queen or the rook, and that is the work of tactics.
