How to checkmate with two rooks
Learn the two rooks checkmate as a pattern you can repeat: one rook builds a fence, the other checks one rank ahead, and they take turns like a ladder until the king is mated on the edge.
A fence, then the ladder
Two rooks mate without help from your king. One rook builds a fence, the other checks one rank ahead, and they take turns climbing like a ladder.
First a fence. Play Rh4: the rook takes the whole 4th rank, and the king can never cross it. Rh4 Kf5
1… Kf5 The king stays on the 5th rank, right next to the fence, and heads for your rook on h4.
Now the other rook checks on the king's rank. Play Ra5+: far from the king, so it can't be taken. The king has to go up to the 6th. Ra5+ Kg6
2… Kg6 The king goes up to g6. That is right next to h6, the square your h-rook would check from.
The a-rook holds the 5th rank now. Next the h-rook should check on the 6th, but the king is waiting next to h6.
Slide away, then climb to mate
When the king stands next to the square your rook wants to check from, don't check yet. Slide that rook along its rank to the far side, then go on climbing.
Rh6+ would just lose the rook: the king on g6 takes it. Slide it to the far side first. Play Rb4: from there it can check on b6, far from the king. Rb4 Kf6
3… Kf6 The king can't go below the 6th rank: your a-rook holds the 5th. It moves along the 6th rank to f6, towards the centre.
Now the ladder goes on. Play Rb6+: the b-rook checks on the 6th, and the king has to go up to the 7th. Rb6+ Ke7
4… Ke7 The king goes up to e7.
The b-rook holds the 6th rank, so the a-rook checks on the 7th. Play Ra7+. Ra7+ Kd8
5… Kd8 The king is pushed to the back rank, d8.
The a-rook holds the 7th, so a check on the 8th leaves the king no square. Play Rb8: checkmate. Rb8#
Checkmate. The whole pattern: a fence, then the rooks take turns checking one rank ahead, and a rook slides to the far side whenever the king comes close.
Key ideas
- Start with a fence: one rook takes the rank next to the king, and the king can never cross it.
- The other rook checks on the king's rank. The king has to step away, one rank further from the fence.
- The rooks take turns: the rook behind checks one rank ahead. That is the ladder.
- If the king stands next to the square a rook wants to check from, first slide that rook along its rank to the far side of the board.
- On the edge the same check is mate. You don't need your king at all.
Common mistakes
- Checking next to the enemy king, so it simply takes the rook.
- Moving the rook that holds the fence, so the king steps back across it.
- Sliding a rook onto the other rook's file, so the rooks get in each other's way.
- Walking your king over to help. It only costs time.
