# Mate in 4 (HARD)

• #1

HINT: Funny little knight move is all it takes! ;-)

Variation:

• #2

ok....

• #3

Nice

• #4

Nothing is forced.

• #5

Actualy it's not forcing. Here is another way for blacks.

• #6

How about Rxd8 in ALL the variations? Black has three connected passers until the White Knight goes for a mate.

Hahahaha You guys are very funny  and quite annoying as well  ! 2... Rh1 also ruins the mate in 4 moves! But if you've not seen the solution above yet, I can tell you: 1. Nb4!

TempterMan! More than that if 2...Rh1 then 3.Qg7 will solve this problem in 5 moves. I discuss the solution where the 1st move is Qc3. And if you look with attention i don't contest your solution with 1st move Nb4. So please be carefull with your comments against people.

prativa_prah your solution isnt forcing mate in 4 moves:

• #13

Also here is another solution with a variation mate in 2 moves:

If 2...any other move than b6 then mate in 2 moves

Come on guy, you may have many solutions to mate in 5 moves, 6, 7 or whatever in this case, but the challenge of this puzzle is to mate in just 4 moves (most puzzles are like this, you may know that), and the only way to solve this problem - no matter what black replies - is 1. Nb4. For any others first moves you try - even goods - black has ways to delay the checkmate to a minimum of 5 moves. I hope you understand my point.

I didn't mean to be harsh on my last comment, but sorry anyway. I just don't want to discuss this anymore.

But you are right, 1. Qc3 can lead to a mate in 5 moves, no matter what black refutes! Ok?
