How to Do the 4-Move Checkmate, Step by Step
The 4-move checkmate is one of the first tricks every beginner runs into, and it belongs on the short list of traps you need to know cold. This guide walks through exactly how it works, move by move, a different move order that leads to the same idea, and why it stops working the moment your opponent knows even a little opening theory.
What Is the 4-Move Checkmate?
The four-move checkmate is a sequence of moves for White that delivers checkmate on move 4, if Black plays along. The whole idea targets the f7 square, which in the starting position is defended by nobody but the black king. White lines up a queen and a bishop against that single weak point, and if Black doesn't react in time, the queen delivers mate right there, guarded by the bishop so the king can't just capture it.
Look closely at f7 in the diagram above. It's under fire from both the queen on h5 and the bishop on c4, and that double attack is what makes the whole trick work. That bishop on c4 is typical of the Italian Game.
If you want the full story behind this pattern, including how to defend against Scholar's Mate whatever White tries, we've written a dedicated guide for that. Here, we're only interested in how to pull the trick off and why it usually doesn't work.
How to Do the 4-Move Checkmate, Step by Step
1.e4 e5
White opens with the king's pawn, Black replies in kind. Nothing unusual yet.
2.Bc4 Nc6
The bishop comes straight out to c4, eyeing f7 from a distance. Black develops a knight, a perfectly natural developing move that ignores what White is about to try.
3.Qh5
This is the move that sets the trap. The queen joins the bishop in attacking f7, and now two attackers are pointed at a square defended by only the king (see the diagram above). Black is already in danger, whether or not Black realizes it.
3...Nf6??
This is the losing mistake. It looks like a normal developing move, and it does attack the white queen, but it completely ignores the threat on f7.
4.Qxf7#
The queen takes on f7, protected by the bishop on c4, and it's checkmate. The black king has no escape square and no way to capture the queen. Four moves, and the game is over.
The Wayward Queen Attack, a Different Move Order
You don't have to bring the bishop out before the queen. Many players go straight for the queen sortie with 1.e4 e5 2.Qh5, an approach known as the Wayward Queen Attack. Black defends e5 with 2...Nc6, White adds 3.Bc4, and the position is the same one as above, reached by a different move order. From there, the trap works in exactly the same way.
Why the 4-Move Checkmate Fails Against a Prepared Opponent
Once you understand the trick, dodging it is easy, which is exactly why nobody who has studied chess even briefly falls for it. Bringing the queen out this early is a well-known mistake in itself. It's simply not a good idea to move your queen so soon in a game, since your opponent develops pieces while attacking it and gains time in the process.
The cleanest answer is to develop a knight to f6 early. A knight on f6 sits directly in the path of a queen coming to f3, so that route to f7 is shut. If the white queen has already reached h5 by the time you notice, a move like 3...Qe7 does the job instead, defending both f7 and the e5 pawn at once. You can follow up with Nf6 next, chasing the white queen away and gaining a tempo of your own.
Timing is what separates the two. Nf6 played on move two is the answer; the same knight move played on move three, once the queen already sits on h5, walks straight into the mate.
Whoever plays the 4-move checkmate is betting entirely on the opponent not knowing the trick. Against anyone who has played more than a handful of games, on chess.com, on Lichess, or across a real board, that bet loses far more often than it pays off. If you'd rather build a real opening repertoire instead of relying on a one-shot trap, our guide to chess opening principles covers the ideas that actually hold up game after game.
We keep the full catalogue of defenses, setup by setup, in our guide to Scholar's Mate. Here, two moves are enough to shut the trick down.
Other Checkmates Worth Knowing
The 4-move checkmate is far from the only quick checkmate worth having in your back pocket. Learning several mating patterns makes it much easier to finish off games cleanly once you get an opponent's king in trouble. If speed is what interests you, our guide to the fastest checkmates in chess walks through the quickest ones.
