Hello and welcome back to another epic video. Look at the position in front of you. It’s white to move and guess what? Checkmate in 7 move! I know, I know, you can’t checkmate with only your knight, or can you? This study is from Dvoretskys endgame manual, also called “the hardest chess book ever”. So can you checkmate in this position as white?
Did you ever thought of checkmating with only your knight? If you said before that is impossible, now you have a new achievement to unlock, I think this is more satysfing than a smoother mate. So let me know if you ever manage the deliver a checkmate like this. Take care and good luck on your games.

Have you ever thought you can deliver a checkmate using only your knight?

Well yes, king and knight VS king is insufficient material and one pawn added isn't. I didn't know how to do it, but if it's not insufficient material, mate is by definition possible.

When this problem was first published, close to a century ago, we were reminded that there are in fact TWO solutions - both using the identical concept, but different paths. [With knights, there are frequently more than one set of moves to get from A to B.] The other line is 1.Kf3 Kh1, 2.Kf2 Kh2 (as you showed here)… then 3.Nd4 Kh1, 4.Nf5 Kh2, 5.Ne3 Kh1, 6.Nf1 (again, as in the other line) h2, 7.Ng3#.

I figured out what the final position would look like, but didn't manage to get there. (btw I think the premise is wrong - it's known that a king and knight can checkmate if the opponent has multiple pieces remaining).

@ChessCrafters-lk4dv 2 ай бұрын

I don’t think it would be possible if black would have another piece on the board. The whole point is to force black to play pawn h2, if black would have another piece than he wouldn’t be force to play that move

@@ChessCrafters-lk4dv I guess another pawn on h4 would be okay

@@taotoo2 There are countless possibilities that all involve a king smothered by his own pieces but it would require foolish moves by the losing player to smother themselves. It wouldn't work in a puzzle as a forced win like this one.

Man I know this pattern but it took me alot of times to find the concrete variations. 1. Kf3 Kh1 2. Kf2 Kh2 3. Nd4 kh1 4. Nf5 Kh2 5. Ne3 Kh1 6. Nf1 h2 7. Ng3#

Given the specificity of the situation, I first looked for the mate position before looking for the moves and saw, from the conclusion of the video (without peeking between) that I was right. Having a target I'll go about it and see what I find.

@ChessCrafters-lk4dv Ай бұрын

Yep, reverse engineering is a very important skill to learn in chess. Sometimes is way easier to calculate from the end than from the beginning

@shanelawson5072 Ай бұрын

That Scandinavian example is NOT actually winning a tempo cos white loses a move with exd5.

you really like to hear yourself talk, this could have been a 3 minute video

@italixgaming915 Ай бұрын

A good way to calculate this kind of things is to see that a Knight only moves to a square of the opposite colour. This is how you understand that you need to waste a tempo with your King. Funny fact: when my opponent doesn't find the resign button, I like promoting all my pawns to Knights and mate the King with them. That practice was useful for that position ^^

That is a great way of underdasting. It's my first time when I hear that and it makes a lot of sense. Thanks for sharing

So the video gives a position where one side has only a knight and is able to force checkmate in seven moves. Can we create a position where the side with only a knight has an even longer checkmate? Yes... how about a position where the mate takes 22 moves! Here is my position, which I found by playing around with a tablebase: White: king on a7, pawns on a6, c2, and e3, knight on c8 Black: king on c7, knight on Nb6 Black to play wins. A key line goes 1...Nxc8+ 2. Ka8 Nb6+ 3. Ka7 Nc4 4. e4 Nd6 5. e5 Nf7 6. e6 Nd8 7. e7 Nc6+ 8. Ka8 Nxe7 9. Ka7 Nd5 10. Ka8 Nb6+ 11. Ka7 Nd7 12. c3 Nb6 13. c4 Nd7 14. Ka8 Kb6 15. c5+ Kc6 16. Ka7 Kc7 17. Ka8 Ne5 18. Ka7 Nc6+ 19. Ka8 Kc8 20. a7 Nd8 21. c6 Ne6 22. c7 Nxc7# Is there a line where the checkmate requires even more moves? I don't know, maybe!

@ChessCrafters-lk4dv 2 ай бұрын

Wow amazing line!! I don’t know if there is another longer line, but I know a shorter line that would preceed this exactly position with white knight on b7, white king on h7, white has a pawn on a2, black has a pawn on a3 and black king is on E5

@psymar Ай бұрын

I don't know how you found this but it's easy enough to improve by 1. From your position, move the black knight to c4, the white king to a8, and replace the white knight with a bishop. The winning line of course now being Nb6+ Ka8 Nxc8 and the rest as before.

@zanti4132 Ай бұрын

@@psymar You meant 1...Nb6+ 2. Ka7 Nxc8+ etc. but you're right - a new longest mate!

@tykemorris 2 ай бұрын

I did solve this, including figuring out the First move for tempo by trial and error really. It wasn't easy, but it is solvable. It helped to work backwards from the final two moves. After that it was vital to keep the knight either able to move to g3 for a checkmate or else the black king had to be blocking his own pawn on h2.

@ChessCrafters-lk4dv Ай бұрын

Congrats on finding the right move. Indeed, working backwards is the easiest way of solving those kind of position
