Definition and pattern

What is Réti's mate?

Réti's mate is a named checkmate where a bishop gives mate while supported by a rook or queen. The enemy king is boxed in by its own pieces, so the attacking bishop only needs to seal the final square. Use the Archetypal Réti Mate diagram to see the shape.

Why is it called Réti's mate?

It is called Réti's mate after Richard Réti, who delivered the pattern against Savielly Tartakower in Vienna in 1910. The game is famous because the mate arrives after a queen sacrifice and a precise bishop finish. Use the Réti vs Tartakower replay to watch the source game.

Which piece delivers Réti's mate?

The bishop delivers the final check in Réti's mate. The bishop is protected by a rook or queen, so the defending king cannot capture it. Use the Final Move Trainer and look at how the rook on d1 supports Bd8#.

What traps the king in Réti's mate?

The king is trapped by its own pieces occupying or blocking the flight squares. In the archetypal position, Black's own knight, bishop, pawn and king-side structure help form the cage. Use the Escape-Square Map to name every blocked square.

Is Réti's mate a bishop mate?

Yes, Réti's mate is a bishop-delivered mate. What makes it special is the combination of bishop support and enemy pieces sealing the king's exits. Use the Pattern Checklist before replaying the final move.

Is Réti's mate common?

Réti's mate is famous but not common. It is more useful as a pattern-recognition lesson than as a frequent forced tactic. Use the Adviser and choose Recognition if the final shape is new to you.

Réti vs Tartakower

What was the famous Réti vs Tartakower game?

The famous game was Richard Réti vs Savielly Tartakower, Vienna 1910. It ended in only 11 moves with the final sequence 9.Qd8+ Kxd8 10.Bg5+ Kc7 11.Bd8#. Use the Replay Lab to watch the full supplied PGN.

What is the final move of Réti's mate?

The final move in the classic game is 11.Bd8#. The bishop lands on d8, gives check, and is protected by the rook on d1. Use the Final Move Trainer to solve that exact position.

What is the queen sacrifice in Réti's mate?

The queen sacrifice is 9.Qd8+ Kxd8. Réti gives up the queen to drag the king onto the wrong square and prepare the bishop net. Use the Combination Trainer to replay the sacrifice before the mate.

Why does 11.Bd8# work?

Bd8# works because the bishop gives check while the rook on d1 protects it along the d-file. Black's own pieces and blocked squares leave the king with no capture, escape, block, or interposition. Use the Escape-Square Map after revealing the trainer.

What opening was the Réti vs Tartakower game?

The supplied PGN begins as a Caro-Kann Defence structure after 1.e4 c6 2.d4 d5. The opening label matters less than the tactical finish, because the page focuses on the mate pattern. Use the Replay Lab if you want to see how the final position arose.

How short was the Réti vs Tartakower mate?

The classic game ended in 11 moves. Its short length is one reason the pattern is remembered so clearly. Use the full-game replay after solving the final-move trainer.

Calculation and training

How should I train Réti's mate?

Train Réti's mate by solving the final move first, then replaying the queen sacrifice sequence. This separates the pattern shape from the forcing calculation. Use the Final Move Trainer before the Combination Trainer.

What should I check before playing Bd8#?

Before playing Bd8#, check that the bishop is protected, the king is in check, and all flight squares are blocked. Réti's mate fails if the bishop can be captured or the king can escape. Use the Pattern Checklist beside the trainer.

Can I practise Réti's mate against the computer?

Yes, the Practice buttons load the exact FENs so you can play the mating move or the combination yourself. This is better than only watching the replay because it tests whether you really see the move. Use Practice after one reveal.

Should I memorise the whole 11-move game?

You do not need to memorise the whole game to learn Réti's mate. The key learning is the final bishop mate and the queen sacrifice that sets it up. Use Replay solution before Replay game.

What is the main calculation idea?

The main calculation idea is decoy and follow-up: Qd8+ pulls the king, Bg5+ drives it, and Bd8# finishes. Each move removes a defensive option rather than just giving a check. Use the Combination Trainer to follow that chain.

What rating level should study Réti's mate?

Réti's mate is a good named-pattern study for roughly 1400 to 1800+ players. Beginners can still enjoy it, but they should also learn simpler bishop and back-rank mates. Use the related links after the page for easier patterns.

Mistakes and comparisons

What is the most common mistake in Réti's mate?

The most common mistake is seeing the final bishop move without checking whether it is protected. In the classic pattern, rook support is essential because the bishop sits right next to the king. Use the Final Move Trainer and trace the rook's support.

How is Réti's mate different from Boden's mate?

Boden's mate uses two bishops on criss-crossing diagonals, while Réti's mate uses one mating bishop supported by a rook or queen. Réti's mate also depends heavily on the defender's own blocked flight squares. Use the comparison cards before moving to Boden's Mate.

How is Réti's mate different from Opera mate?

Opera mate is usually a rook mate supported by a bishop, while Réti's mate is a bishop mate supported by a rook or queen. The supporting and mating pieces are reversed. Use the comparison cards to keep those roles separate.

How is Réti's mate different from back-rank mate?

Back-rank mate usually traps the king behind its own pawns on the first or eighth rank. Réti's mate traps the king with several of its own pieces and finishes with a supported bishop. Use the Escape-Square Map to see the difference.

Can Réti's mate happen without a queen sacrifice?

The named classic includes a queen sacrifice, but the final pattern can be recognised without the exact same move order. The important features are the supported bishop and the blocked enemy king. Use the Archetypal Réti Mate diagram as the pattern anchor.

What should I study after Réti's mate?

Study Boden's Mate, Opera Mate and Back-Rank Mate after Réti's mate. They reinforce bishop support, rook support, and enemy-piece blockage in related ways. Use the related links at the end of the page.

Page tools

What does the Final Move Trainer teach?

The Final Move Trainer teaches the exact final position before 11.Bd8#. It makes you identify the supported bishop mate without replaying the whole game first. Use Reveal answer only after you have chosen a move.

What does the Combination Trainer teach?

The Combination Trainer starts before 9.Qd8+ and shows the queen sacrifice route to mate. It is the best tool for understanding why the final position is forced. Use Replay solution before Replay game.

Why does the page include a replay game?

The replay game shows how the famous position arose from the supplied PGN. It gives historical context after the pattern has been solved actively. Use the Replay Lab after the trainer cards.

What should I look for in the final diagram?

Look for the mating bishop on d8, the supporting rook on d1, and the black pieces that block the king's exits. Those three features define the pattern visually. Use the Escape-Square Map before moving to the FAQ.

Can I use this page as a quick puzzle?

Yes, start with the Final Move Trainer and try to solve it as a one-move puzzle. Then use the Combination Trainer as a short forcing-line puzzle. Use Practice to play the moves on the board.

Why is Réti's mate worth adding to the index?

Réti's mate is a named, historic, and memorable checkmate pattern. It deserves an index entry because players search for the name and the 11-move miniature. Use the index entry with the 1600+ badge.
