A windmill in chess is a repeated checking sequence, usually built around discovered checks, that lets one side win material while the enemy king is forced back and forth. Use the replay lab below to watch famous windmills move by move and see exactly why the pattern works.

A windmill is a tactical sequence where repeated discovered checks force the king to move while another piece captures material each turn.
The classic windmill is easiest to understand when you see the key attacking pattern in stages.
The boards below restore the original staged teaching sequence so the page explains the tactic visually as well as interactively.
25.Bf6!!
White offers the queen. If Black takes with 25...Qxh5, the rook on g3 and bishop on f6 create the deadly battery that starts the windmill.
Carlos Torre Repetto vs Emanuel Lasker, Moscow 1925.
The cycle begins: 26.Rxg7+ Kh8 27.Rxf7+ Kg8 28.Rg7+ Kh8
The rook keeps checking while harvesting material. The black king has almost no freedom, so White can continue the back-and-forth destruction.
This is the core windmill mechanism: check, force the king, reset, and check again.
32.Rxh5
When the sequence ends, White has recovered the queen and reached a winning position. The windmill has done its work: the king was tied down and Black's pieces were picked off one by one.
Finish: 32...Kg6 33.Rh3 Kxf6 34.Rxh6+ Kg5 35.Rh3 Reb8 36.Rg3+ Kf6 37.Rf3+ Kg6 38.a3 a5 39.bxa5 Rxa5 40.Nc4 Rd5 41.Rf4 Nd7 42.Rxe6+ Kg5 43.g3 1-0
26.Qxe4!
Alekhine sacrifices the queen to open lines and expose the king. After 26...fxe4, the bishop on g2 becomes a powerful attacking piece.
Alexander Alekhine vs A Fletcher, London 1928 simul.
27.Bxe4+
The king is driven into the corner, and the knight joins the attack with repeated checks. The sequence finishes with 32.Nf7#.
Not every windmill ends by winning material first. Some crash straight through to mate.
A windmill in chess is a repeated checking sequence, usually built around discovered checks, that lets one side win material while the enemy king is forced back and forth. The replay lab and staged diagrams on this page show the pattern move by move in famous examples like Torre vs Lasker.
The windmill tactic is a tactical pattern where one piece keeps giving checks while another capture or return move restarts the checking cycle, so the defender loses material move after move. The visual examples and replay section below make that repeated cycle much easier to recognise in practice.
No. A windmill is a special repeating form of discovered attack, while a single discovered attack by itself is not enough. The Torre sequence on this page shows how the idea becomes a full windmill only when the checks keep restarting.
No. A single discovered check is not a windmill because the pattern must continue through a forced cycle of repeated checks. The replay lab helps show the difference between one tactical shot and a true repeated windmill sequence.
No. The classic windmill usually uses a rook and bishop, but rarer versions can involve other pieces if the same repeated checking mechanism exists. The examples on this page start with the classic rook-and-bishop form because it is the clearest way to learn the pattern.
Sometimes, but only if the same repeating forced-check cycle is genuinely there. The examples and explanations on this page help separate true windmills from tactical combinations that only look similar at first glance.
Yes. Winning material is the most common result because every move is a check and the defender often has no time to save loose pieces. The Torre diagrams below show exactly how a windmill can strip away material while the king is trapped.
Yes. Some windmills win material first and then finish with mate, while others are mating attacks almost from the start. The Alekhine example on this page shows how a repeated attacking sequence can drive the king straight into mate.
Yes. A windmill can sometimes force perpetual check or repetition when a worse side cannot do more than keep the king trapped in the cycle. The replay collection includes examples that show the pattern is not only a winning weapon but also a drawing resource in some positions.
The windmill is powerful because checks are forcing moves, so the defender often has no time to organise a normal defence. The replay lab and step-by-step boards on this page show how quickly the attacking side can take over once the cycle starts.
Look for an exposed king, a long-range line piece, and a checking move that can be repeated after each forced king move. The staged diagrams on this page are designed to train your eye to notice that setup before the full sequence begins.
A skewer is usually a single line attack on two pieces, while a windmill is a repeating tactical cycle with checks and repeated gains. The examples below make that difference clear by showing a windmill as a whole sequence rather than a one-move tactic.
A fork attacks two or more targets at once with one move, while a windmill keeps restarting through a series of forcing checks. The replay lab helps show why a windmill feels more like a tactical machine than a single double attack.
Yes. Torre vs Lasker from Moscow 1925 is the best-known windmill example and is usually the first game players study when learning the pattern. The page places that game at the centre of both the replay lab and the diagram walkthrough for exactly that reason.
Yes. Byrne vs Fischer contains a famous repeated-check sequence that is often cited as a windmill-style tactical destruction, even though many players first remember the queen sacrifice. The replay selector lets you compare it directly with Torre vs Lasker and judge the pattern for yourself.
Another common name for the windmill is seesaw. The examples on this page make that name easy to understand because the checking piece keeps driving the king back and forth in a repeated rhythm.
A full windmill is rare because the attacking side needs a very specific setup with an exposed king, limited escape squares, and a way to restart the checks each move. That is why the replay collection on this page is useful: it gathers several clean examples in one place.
The best way to practise the windmill tactic is to replay classic examples and study the positions just before the sequence starts. The replay lab and staged boards on this page give you both the full games and the key teaching moments.
