There is a classic checkmate that works in just 4 moves against unsuspecting beginners. It is called the Scholar's Mate. I'll teach you how to deliver it, how to defend against it, and why you shouldn't rely on it to win.
You're playing White. The idea is to attack the f7 square — the weakest point in Black's position at the start, because it's defended only by the king.
You push the central pawn. Your opponent copies you. A normal opening move.
Your bishop comes out to c4, aiming directly at the f7 square. Black develops a knight (a natural move).
You bring the queen out to h5. Now the queen and the bishop are both aiming at f7. If your opponent doesn't notice the threat and plays any random move (like 3...Nf6, attacking the queen), you get the mate on the next move.
The queen captures on f7. The f7 pawn was defended only by the king, so only the queen could capture it while being protected. The queen on f7 attacks the king (check), and the king has nowhere to run: g8 is occupied by the knight from f6 (which moved away), e7 is occupied by the bishop, and the king can't capture the queen because it's protected by the bishop on c4.
It works for three combined reasons:
The correct defense is simple and comes in several forms. The most solid one is:
When White plays 3.Qh5, the best response is 3...g6 — attacking the queen with a pawn. Now the queen has to retreat (or go to a risky square), you still have your pieces developed, and the threat is over.
The black queen goes to e7, defending f7. It works, but it's less elegant because it gets in the way of development (the bishop on f8 gets stuck).
If you know your opponent likes the Scholar's Mate, you can play 2...Nf6 on the second move instead of 2...Nc6. The knight attacks the e4 pawn and forces White to defend, disrupting the plan.
Another classic trap: White sacrifices the queen for a knight, but delivers mate with the minor pieces. Example:
1.e4 e5 2.Nf3 d6 3.Bc4 Bg4 4.Nc3 g6?? 5.Nxe5 Bxd1?? 6.Bxf7+ Ke7 7.Nd5#
It works because Black gets dazzled by the "queen sacrifice" and doesn't see they're caught in a mating net.
The fastest possible checkmate, in just 2 moves. It only happens if White plays two absurd moves in a row:
1.f3 e5 2.g4?? Qh4#
Practically impossible in real games. But it's an interesting curiosity: the fastest checkmate theoretically possible.
As shown above, the Fool's Mate is the two-move checkmate. It depends entirely on your opponent playing two bad moves. In real games it virtually never happens — but it's the answer to the question "what is the fastest checkmate in chess?".
After a few weeks of playing, every opponent knows how to defend against the Scholar's Mate. If you try it against someone more experienced, this is what will happen:
The lesson: learn the Scholar's Mate so you can defend against it, not to use it as your main strategy. Players who rely on "traps" against beginners never improve.
Practice both the attack and the defense against the computer. Use the Easy level to try the mate, and the Medium level to train the defense.
