# Checkmate on 4th Move

## Question

You don't have to be a chess player to solve this one. But you have to know the rules of chess.

From starting position White moved 1) pawn f3, 2) King f2, 3) King g3, and 4) King h4.

Find the moves for Black so that they checkmate White King on their 4th move.

All moves must be legal.

I gave this puzzle to many a chess master, and they all had very hard time solving it.

White -- Black

1. f3 -- e5

2. Kf2 -- Qf6

3. Kg3 -- Qxf3 (this is the compliance bit the queen should be taken by the king, either pawn, or even the knight)

4. Kh4 -- Be7 checkmate

Unless I'm mistaken - you broke the rules - white has moved four times, black none ???

I guess knowing them and breaking them is two different things

Not at all. Black made their move after each White's move. Your task is to find those moves.

White Black

1. f3 -- ?

2. Kf2 -- ?

3. Kg3 -- ?

4. Kh4 -- ? checkmate

Replace question marks with the moves for Black.

Sorry Rookie, I dont fully understand?

Did you mean move Pawn g5 instead of moving Qf4?

If you did then the king will be able to avoid Checkmate by moving Kh5

I mean that the white g-pawn can get in the way ... see the picture below

Howzit norm

To move Qa5 you would have to move the Pawn in c7...

I've only managed to get to Checkmate in 5 moves so far. hope someone posts the ans soon

And thanks to Rookie1ja and Gambit for showing how some other variations submitted here were not a solution.

And here is the illustration of the solution:

Position after 4 moves:

1. f3? e6

2. Kf2?? Qf6

3. Kg3?? Q:f3+??

4. Kh4?? Be7 checkmate (0-1)
