Well, Anderson proved that in the Immortal Game, where he used three minor pieces to deliver a checkmate. A knight was decoyed by the queen for it to happen.
There’s one I saw can’t remember who it was but they basically sac queen so they could advance a pawn and that’s what won in the following move. That move was massive gigabrain.

Yes, and I'd say any good chess teacher would do the same. Knowing exactly why certain seemingly intuitive moves aren't the solution is almost as important as knowing why the correct moves win.
@@alhfgsp even more so, id say. im a newcomer but i can’t count how many times ive thought i had a mate in the bag just to realize the move was defendable
@@CyberchaoX Because white can escape to Kd1, which leaves black with no follow up checks nor any effective place to put the rook so white pawn promotes. So black Rc2 loses the game. One thing Nelson did not examine is White Kc3 with black Rc2 followed by white Kb4. This is a better move for white than Kd4 which loses the game as he showed, but it ends in a draw. White king would be in perpetual check because it would need to avoid the d file as Nelson showed but it could never capture the rook due to subsequent check by the Bishop. Any attempt by the trapped white king to capture the Bishop would require going to the 7th rank, which would allow the Black rook to check White's king on the 7th or 8th rank, thereby losing the pawn. The white king can't save their pawn while avoiding perpetual check so it would be trapped.
This is the best endgame puzzle I’ve yet seen, wow! A very simple, realistic position. Counterintuitive moves that are so uninstinctive. A knight checkmate against a bishop. So many awesome components.
@@jiogcyihsugyiocjfdoivhphvw6821 Objectively this wasn’t that hard. There’s plenty of chess puzzles that I can’t figure out but this one was not hard at all.
The interesting thing is that chess engines, after 1.f7, will play 1...Rg8, only because it pushes checkmate out much farther than the line you presented (mate in 35 instead of mate in 13). In fact, there are many ways that Black can delay checkmate. But your line is by far the most elegant.
This is one of those puzzles where when it is broken down into smaller puzzles, all of the moves are relatively easy to find, but it's really hard to see all of these ideas from the opening position.
At 6:58 couldn’t you do the same fork move with the knight as in the solution to the puzzle? When the rook moves to F8 you can play Kng6 with check (not mate) and fork the rook? Then you can move the knight and promote for mate eventually. I know it’s not quicker but that works too right? Please let me know if there’s a way to stop it :)
This was my thought as well, and I'm not even sure if it's slower. I couldn't see a way to stop it, but then again I haven't played a game of chess in YEARS and I've never studied the theory, only bits and pieces that I come across by happenstance (such as YT recommending me a video).
@@adampizzi8870 You're right, d8 f's everything up, and suddenly black's winning again. We spent half the game dancing around with the king to prevent black from getting to d8 earlier.
Oh, the agony!!!....On ICC the computer would declare the bishop vs. knight ending a draw due to lack of mating material.....one move before the checkmate.
Just wanted to mention that at 7:30, Kh6 is actually better not just because it’s a showoff move bragging that you don’t even have to keep your king next to your pawn to defend it and get a queen, but also because it’s a faster checkmate, as black has to move the bishop somewhere and the next move f8 (I have no idea how to notate pawn promotions, but queen) checkmate P.S. Okay, as I was typing this, I saw that Be6 (or h7) - f8 queen and check allows for Bg8, blocking, so it takes an extra move of Qf6 (or Qg7) to deliver mate, so the line Nelson mentioned is mate in the same amount of moves cuz if the bishop moves to e6 (or h7) before f8 queen (Bc8 - f8 queen check - Kh7 - Qg7#, for example), after f8 queen check and the bishop blocks, Qg7 is mate, so… hey, it’s still cooler, can’t deny
These are one of the reasons why Chess is so fascinating especially with that knight checkmate that was pretty complex, yet very smart and Chess Vibes showed us why this 1951 chess game got 1st Prize.
I am not surprised it won first place. When people talk about 'the beauty of chess', I believe people think, "it's just a board game, what are you talking about"? the above puzzle is a perfect example of that beauty.
It looks so simple. You think it's not that complex because there aren't many pieces on the board, but it's incredibly complex, and it shows how complex chess is.
I am not a good chess player but I still very much enjoy analyses like this. I actually found each of the right moves (surprised myself). Analyses allow us to share thoughts with each other and that's cool.
The only part of the video I predicted correctly was Knight to E7 and onward to checkmate. I'm no chess player, and this video made me feel like there's a reason for that
I just started watching chess channels and doing puzzles after not playing since college 17 years ago. I’m a dreadful player, but I do fairly well at puzzles where I know there’s a particular thing to find rather than needing my own intellect to see it. This puzzle was awesome and brilliantly explained, along with all the alternative outcomes if different moves were played. As someone who isn’t good at the game, watching this kind of stuff is similar to watching a conjuror do an illusion and leaving you confused about how it was done. It’s a similar feeling. Subscribed!
Especially cool since you called out that a knight and a king are not enough to force mate…but in this case it was enough. Thank you for sharing this with us!
1:45 "White has to make a decision where to move the king to." Well, I would've moved my bishop to A3 actually, but if I have to move the king then B2 I guess. "Trick question, don't move the king. Bishop to A3." WTF
Never watched your channel before, just wanna comment that immediately I appreciated how concise and quiet your title card/intro thing was. Too often bombarded by loud music and some crazy animation for a channel logo that lasts way too long. Right to the good stuff. Keep it up
At around 4:30: I had to wonder what would happen if the king moved to B4 after the move to C3. I can see that moving the king to take the bishop wouldn't work (the rook can swing up once the king is on the same row as the pawn, and the king wouldn't be able to take because the bishop would be guarding the rook. The end result would be losing the pawn). My end conclusion is if the king moves to row 7, the rook swings up to row 2 under the protection of the bishop to check the king and ultimately take the pawn. If the king moves to column d (on any row), the swing-up threat shown in the video is still present (though may end with all pieces except the bishop getting taken). I do have to wonder if there is anything else about this that I'm missing.
To let you know how rare this is, here are the conditions of this very rare king+knight vs king+bishop checkmate: 1. The black king has to be in the right corner. 2. The black bishop has to be the right color. 3. The white king has to be in position already. 4. The white knight has to be in position already. 5. The position has to be forced. In this case, the black bishop is forced to take the promoted queen.
The game logic on most chess sites would make it a draw but over-the-board your opponent couldn’t claim a draw because you can demonstrate mate in one.
I was looking at the board at 7:00 thinking that the king to f6 would actually work, then follow up with the exact same forks from the knight.... Then watched the rest of the video and it's way more creative and awesome to do it the way you show.
If playing Kf6...Rg8, KNe7(Fork)...Be6 leads to a draw since there is no mate threat from KNg6. It's the threat of mate after the fork which is possible with Kh6. Agree that should have been discussed, took me a bit to work it out.
Indeed, this was really a beautiful one. I wonder how you do design a puzzle. Do you reverse engineer it from the end? Do you take inspiration in your real games and calculations?
4:43 I REALLY need to know why Kb4 doesn't work from this position, Nelson doesn't address this option. Why can't you just walk the king up the board over the black squares of the a and b files and go after the bishop? The rook has to keep checking you, but it can't stand next to the king on a higher diagonal where the bishop can't fork the king with the pawn, so it is forced to keep moving between a2 and b2. So it doesn't come into a position where it can prevent the pawn's promotion. What am I missing?
it is answered in the video. but its a bit complex. The difference is that if black king go Kc3.. it become apparant when looking at the checking potential when king come to d file... the rook has the potential to check from d2.. see position at 4:48. in this situation the black rook has the posibility to go Rd8. in the move before 4:33 white king cant go to d3.. because of the bishop forking knight and king again.. and in the other situation.. when King go Kc1.. when arrive in d file.. the king is lower down potentialy on d2 if rook try check from d1.. the king can just take it.. and cant use trick to get acces to d8.. see 5:18... just compare 5:18 and 4:48 the key is in 4:48 tactics work to defend.. but not in 5:18 in short words.. if Kc3.. the rook has a way to perfectly exploit the fact the king can never enter b1-c2-d3-e4 diagonal because of the fork.. and then when enter the d file.. he can enter into e8 in time to defend transformation square.. when king go Kc1.. black dont have the tactics to check the king in a whay where he can draw the white king onto this diagonal..where before the king would be higher up in the middle and the check would draw the king one the forking diagonal if white was to take the rook. hope that helps.
Thank you, I was wondering about that line and why rook wouldn't just move to c2 and put the king into a similar trap where the knight is taken if the rook is (in turn putting the king in check.)
@7:01 I wish you had given a bit more info on why its not enough. White had the option to fork bishop and rook at that point, and playing that through a little more would have been nice.
question: would underpromotion to a rook work? just to flex on your opponent i don't see anything wrong with that, unless i'm missing something, you know how is it like to be below 1500
You should specify when white would do that, but I believe it would, as rook vs bishop is a draw (at least in this case, since black’s king is in the right corner)
@@Kat-dp4rh I was assuming in the spot towards the end where white can actually promote the pawn to a queen, because black's only legal move is to capture it. The rook or queen isn't actually important, white checkmates with the knight and king. (No, really, watch the whole vid.)
i struggled to see some of the parts of this puzzle just going through it (i did not see the bishop sacrifice) but i am extremely proud that i saw that knight fork into forced checkmate at the end. i dont play chess much so it made me somewhat happy
6:53 can anyone explain why Kf6 is not winning? The line shown where black responds with Rg8 seems to lose to the same Ne7 as in the intended solution. What can black do to draw from that position?
Its losing because after 1... Rc2 2.Kd1 Black could no longer give a sacrificial rook check with a bishop chech follow-up. If black rook tries to check, white will just take it for free and win.
I can tell you that the author began the study from the final checkmate position and worked backwards to the starting position. This is how all the studies are worked out. You don't randomly pick a starting position and hope it will end up in such a wonderful checkmate.
at 5:02 why can't black play rook to c2 check? I am missing that part in your video, does it lead to a previous constellation? Can someone explain pls?
4:24 king takes rook, pawn gets to go forward and forces king to move, takes bishop since it couldnt move due to the king having to move out of check, king and queen vs king could probably check
After white king takes rook, black king moves to g7 and on next move either take pawn on f7 with king if white moved king or if white promoted queen on f8 black king takes queen and white have only king left against king and bishop, which is draw. The point is that white are forced to move king after black bishop had taken knight with a check, thus giving time for black king to move closer to pawn
You can try to send it to cjx ─ he posts puzzles regularly, and ever since I first sent one of my puzzles to him, he also explains puzzles composed by his own viewers. He's already featured 5 of mine :)
This is the ending line of a very famous study from the 1950s. White to move, with a white pawn on f6, a white knight on f5, a white bishop on c1, a black rook on g6 and a black bishop on c8. Kings are on a1 for white and h8 for black. Check this study out if you have the time, what is shown in this shirt is only the end, where the rook checks the king all the way from a1 to h6, where the first check (Ra6+) involves a very pretty idea Ba3!!, which is the trickiest part of the study. Super cool, and it won a prize.
Excellent puzzle which I did not correctly solve. An interesting variation that doesn't work for white just before 17 minutes... After the white to Kf6 blunder, instead of the pawn capture leading to an immediate draw, white Ne7 threatens checkmate on the next move. Black can't use Rf8 because it leads to a white Ng6 fork to capture the rook for free with check tempo. The only move for black is Be6. This forces the white king to capture the Bishop Ke6. This allows a more effective black Rf8 move, as after white Ng6, Black King can escape to the g file at Kg7. Now when white captures the rook at Nf8, Black captures the knight on f8, which blocks the pawn and forces stalemate. So the variation doesn't work. Here is the sequence. W Kf6 blunder B Rg8 W Ne7 checkmate threat B Be6 W Ke6 captures bishop B Rf8 W Ng6 check fork B Kg7 W Nf8 captures rook B Kf8 captures knight W Kf6 stalemate
That is such a complicated puzzle to analyze, but seeing the solution is amazing. This is truly a great puzzle, and you are right, it deserved the win. Thanks for sharing!
At 5,49 rock can also go to a5… Because if white get a queen rock takes knight check fork the queen.. white take the rock whit the queen black take it back whit the bishop
There isn't insufficient material there. Knight + king vs. king is insufficient material, because checkmate is impossible. Knight + king vs. bishop + king is NOT insufficient material, because a checkmate can happen.
@@oenrn yeah, that's the fide rules, but from what I know, the American federation has different laws regarding to that (which is dumb, and this is a good proof). Now I believe that, even in the USA, no arbiter would declare it a draw, and computers neither since there is mate in 1
Only part that wasn't explained and I don't know the answer is at 7:04 once king is on H6, how does white respond to bishop taking the knight instead of using the rook?
ever since I found out that theoretically a knight against a bishop could be a win I always wondered how a game could reasonably end like that. this puzzle demonstrated that so well!

Then watched the rest of the video and it's way more creative and awesome to do it the way you show.
If playing Kf6...Rg8, KNe7(Fork)...Be6 leads to a draw since there is no mate threat from KNg6. It's the threat of mate after the fork which is possible with Kh6. Agree that should have been discussed, took me a bit to work it out.
Great! I didn't get all the tricks, but did guess most of them.
Awesome puzzle, thank you for showing us!
5:03 why not rook to c2 checking because king can't take because of bishop takes knight and check?
Pls someone explain
Indeed, this was really a beautiful one. I wonder how you do design a puzzle. Do you reverse engineer it from the end? Do you take inspiration in your real games and calculations?
4:43 I REALLY need to know why Kb4 doesn't work from this position, Nelson doesn't address this option.
Why can't you just walk the king up the board over the black squares of the a and b files and go after the bishop? The rook has to keep checking you, but it can't stand next to the king on a higher diagonal where the bishop can't fork the king with the pawn, so it is forced to keep moving between a2 and b2. So it doesn't come into a position where it can prevent the pawn's promotion. What am I missing?
5:03 after Kc1, why is Rc2 not the same as Kc3, Rc2? Maybe Kd1?
Exactly, Kd1. Black has no more moves then
@@BorisGamingChannel bishop will take a knight and continue to forking pawn and king.just analyze it and u will get it
@@paklang8667 if he takes the knight we promote, it is not check
@@paklang8667 Bishop cant fork king and pawn when king is on c1, c3 or d1. i think you mixed up the positions.
it is answered in the video. but its a bit complex. The difference is that if black king go Kc3.. it become apparant when looking at the checking potential when king come to d file... the rook has the potential to check from d2.. see position at 4:48. in this situation the black rook has the posibility to go Rd8. in the move before 4:33 white king cant go to d3.. because of the bishop forking knight and king again..
and in the other situation.. when King go Kc1.. when arrive in d file.. the king is lower down potentialy on d2 if rook try check from d1.. the king can just take it.. and cant use trick to get acces to d8.. see 5:18...
just compare 5:18 and 4:48 the key is in 4:48 tactics work to defend.. but not in 5:18
in short words.. if Kc3.. the rook has a way to perfectly exploit the fact the king can never enter b1-c2-d3-e4 diagonal because of the fork..
and then when enter the d file.. he can enter into e8 in time to defend transformation square..
when king go Kc1.. black dont have the tactics to check the king in a whay where he can draw the white king onto this diagonal..where before the king would be higher up in the middle and the check would draw the king one the forking diagonal if white was to take the rook. hope that helps.
For those wondering about Kc1 Rc2+ leaves 3 options
Kxc2 Bxf5+ K... Kg7 draw
Kb1 Rg2 f8Q+ Rg8 Qh6 mate
Kd1 rook cannot safely check the king, neither can the bishop, cannot attack f8, white wins
Thank you, I was wondering about that line and why rook wouldn't just move to c2 and put the king into a similar trap where the knight is taken if the rook is (in turn putting the king in check.)
Nice puzzle. Would have appreciated if you made a recap at the end with all the moves in one go.
@7:01 I wish you had given a bit more info on why its not enough. White had the option to fork bishop and rook at that point, and playing that through a little more would have been nice.
1:52
King A1 to B2, (because of his Bishop)
I fell for that.
Believed you, I believed you, should have know better than that.
5:04 “So check this out”
What a pun
question: would underpromotion to a rook work? just to flex on your opponent
i don't see anything wrong with that, unless i'm missing something, you know how is it like to be below 1500
If you mean in the main line, yes, it would, as the white king prevents black from escaping on the one relevant square the rook doesn't hit (h7)
You should specify when white would do that, but I believe it would, as rook vs bishop is a draw (at least in this case, since black’s king is in the right corner)
@@Kat-dp4rh I was assuming in the spot towards the end where white can actually promote the pawn to a queen, because black's only legal move is to capture it. The rook or queen isn't actually important, white checkmates with the knight and king. (No, really, watch the whole vid.)
Ah, at that point, then no, it wouldn't make a difference
i struggled to see some of the parts of this puzzle just going through it (i did not see the bishop sacrifice) but i am extremely proud that i saw that knight fork into forced checkmate at the end. i dont play chess much so it made me somewhat happy
This puzzle feels like a mario level, it starts with a simple concept which slowly gets more and more complex over the course of the puzzle
You mean the level with this 💩ton of lasers you have to avoid counterintuitively most of the time?
@@shuetomtqasaab Wellllllllll, if its creative!
6:53 can anyone explain why Kf6 is not winning? The line shown where black responds with Rg8 seems to lose to the same Ne7 as in the intended solution. What can black do to draw from that position?
Ah, the issue is Rd8 doesn't have a mate threat Ng6 like it does in the solution.
I don’t understand why at 5:05 rook to c2 isn’t mentioned
Its losing because after 1... Rc2 2.Kd1
Black could no longer give a sacrificial rook check with a bishop chech follow-up. If black rook tries to check, white will just take it for free and win.
King d1 and white wins
White: "One knight is not enough"
Also White: One knight checkmate is the solution to this puzzle
I can tell you that the author began the study from the final checkmate position and worked backwards to the starting position. This is how all the studies are worked out. You don't randomly pick a starting position and hope it will end up in such a wonderful checkmate.
at 5:02 why can't black play rook to c2 check? I am missing that part in your video, does it lead to a previous constellation? Can someone explain pls?
I was just wondering the same thing
Edit: another comment explained kd1 makes black lose in that position
I didnt have a favorite chess puzzle before this video. I do now. That was beautiful.
8:23 i thought it rg7 then qf8 and rook has to block so rg8, qxg8 checkmate because horsey is protecting queen and king is blocking the ways
Very cool study, so tricky.
4:24 king takes rook, pawn gets to go forward and forces king to move, takes bishop since it couldnt move due to the king having to move out of check, king and queen vs king could probably check
After white king takes rook, black king moves to g7 and on next move either take pawn on f7 with king if white moved king or if white promoted queen on f8 black king takes queen and white have only king left against king and bishop, which is draw. The point is that white are forced to move king after black bishop had taken knight with a check, thus giving time for black king to move closer to pawn
@@ankor7625 ah thank you
god damn i saw that mate from afar but that single knight mate is just mannnnnnnnnnn
SO great. So easy to follow along
I'm glad you enjoyed this but could you find another expletive? That one is just so god damned ugly. See what I mean?
Amazing creativity to find such a puzzle from scratch
How to send a puzzle to Chess Vibes? I'd like to share a study I've created and watch it described by Nelson Lopez
You can try to send it to cjx ─ he posts puzzles regularly, and ever since I first sent one of my puzzles to him, he also explains puzzles composed by his own viewers. He's already featured 5 of mine :)

What cjx? Where?

This is the ending line of a very famous study from the 1950s. White to move, with a white pawn on f6, a white knight on f5, a white bishop on c1, a black rook on g6 and a black bishop on c8. Kings are on a1 for white and h8 for black. Check this study out if you have the time, what is shown in this shirt is only the end, where the rook checks the king all the way from a1 to h6, where the first check (Ra6+) involves a very pretty idea Ba3!!, which is the trickiest part of the study. Super cool, and it won a prize.
Great video, showed this to my teacher and took quite a while to solve it
You put him in a really tight spot haha
Excellent puzzle which I did not correctly solve. An interesting variation that doesn't work for white just before 17 minutes... After the white to Kf6 blunder, instead of the pawn capture leading to an immediate draw, white Ne7 threatens checkmate on the next move. Black can't use Rf8 because it leads to a white Ng6 fork to capture the rook for free with check tempo. The only move for black is Be6. This forces the white king to capture the Bishop Ke6. This allows a more effective black Rf8 move, as after white Ng6, Black King can escape to the g file at Kg7. Now when white captures the rook at Nf8, Black captures the knight on f8, which blocks the pawn and forces stalemate. So the variation doesn't work. Here is the sequence.
W Kf6 blunder
B Rg8
W Ne7 checkmate threat
B Be6
W Ke6 captures bishop
B Rf8
W Ng6 check fork
B Kg7
W Nf8 captures rook
B Kf8 captures knight
W Kf6 stalemate
The end gave me goosebumps
At 7:00 can't white play Ne7 as well? I don't understand why that wouldn't be an option.
Imagine getting this far just to lose on time. 😔
- "Good job by Black for defending the position... oh, wait a minute... Knight mate"
- Mind explodes
that position was a headache for me !!!🤣
nope, only if u have a brain, which ur lacking
That is such a complicated puzzle to analyze, but seeing the solution is amazing. This is truly a great puzzle, and you are right, it deserved the win. Thanks for sharing!
I saw all of that of course
At 5,49 rock can also go to a5…
Because if white get a queen rock takes knight check fork the queen.. white take the rock whit the queen black take it back whit the bishop
If white gets queen.. its checkmate
wouldnt it be a draw by insufficent material just before the checkmate ?
Yeah that’s what I’m wondering too
Not if there's a forced mate.
There isn't insufficient material there.
Knight + king vs. king is insufficient material, because checkmate is impossible.
Knight + king vs. bishop + king is NOT insufficient material, because a checkmate can happen.
@@oenrn yeah, that's the fide rules, but from what I know, the American federation has different laws regarding to that (which is dumb, and this is a good proof). Now I believe that, even in the USA, no arbiter would declare it a draw, and computers neither since there is mate in 1
@@oenrn More specifically, the side with the knight can mate. The side with the bishop cannot.
Only part that wasn't explained and I don't know the answer is at 7:04 once king is on H6, how does white respond to bishop taking the knight instead of using the rook?
