- This is puzzle is amongst the most famous in chess history! It was originally composed by George Barbier and perfected by Fernando Saavedra after he tranformed it from a draw position into winning for white by finding a genius move in 1895.
White to move and win. Can you find how?

I did solve it, but didn't notice the Rd4 stalemate trap. Once you showed it, I saw the Underpromotion. Having done so many of these puzzles with underpromotion solutions, it seems impossible that the composer didn't see it, let alone the entire chess world.
According to en.wikipedia :
The stalemate trick was proposed by G.E. Barbier on 4th May of 1895, solution published 11th May as a draw, refuted by Saavedra in the following days, republished by Barbier with that correction the 18th May.
Comes from a game played in 1875 where they agreed to a draw, while the king could do that little dance and force promotion to a queen and win, as noticed by Zukertort.
The initial study published 27th April 1895 after the recent death of the player with the black pieces, focused on that manoeuver and had black king positionned as in the game (but misremembered), additionnal puzzle with the king in the corner and the stalemate trick came like some days after the initial study, as stated above, so kind of an improvisation from Barbier, thus the lack of finding the winning line.
The modern form is fixed by Lasker in 1902, putting the white pawn back to c6 (not on c7).
@@lonewolf42923 if Black dies move the King to b2 instead of faffing around with the rook what what is the best way to proceed after promoting to a queen? I keep ending up in stalemate.
@@peteneville698 You mean black allows the queen promotion and tries to draw in a queen vs rook endgame ?
Yeah not sure I would succeed yet in a real game, but I'm training, funnily enough it's the video about that endgame that brought me to this channel, so check it ;)
I kind of agree, but maybe the fact that you have equal material (and it's black's turn to move his rook first after white gets his rook) caused people to discard underpromotion and not read it out. K+R vs K+R is usually a draw I believe.
@@peteneville698 Hey, I thought I had answered you but the comment has disappeared or was never posted.
Yes, the endgame Q vs R is hard, I know two or three ways to win with B+N and haven't found the definitive way in Q vs R.
I had answered that funnily enough it's a video about that endgame that brought me to that channel. It was a good video, among dozens of not very useful ones found elsewhere. But still I don't consider I mastered that endgame at all.
Oh yeah, I remember this puzzle from the book All About Chess by I.A. Horowitz. I love that underpromotion to a rook. From the start of the puzzle, Stockfish has it as a mate in 26. The rook chasing the king is essential to point out for the beautiful rook promotion, but at anytime black can move it's king instead, white would promote to a queen, then it's a game of queen vs rook. I'm actually not good at queen vs rook endgames. Incase my opponent with a rook doesn't resign, I have to study how to mate with a queen against a rook, or it would be a draw. If black keeps with the king chase, do promote to a rook but if it doesn't keep with the chase, promote to a queen and know how to mate with a queen against a rook.
You are just brilliant... Excellent puzzle. Thank you very much and God bless you Sir
I’ve seen this puzzle before. You got to play the precise moves, even with only four pieces on the board.
Black's first move should be 1....Rd2, let the pawn queen, and then get a perpetual by checks on the a and b columns or exchange for the queen if white's king moves to the c column... no?!?
Excelente, Saavedra was very clever👍👍👍
I learned this when I was in the 7th grade in the chess club, which was over 40 years ago. I showed it to a grand master in a chess team and he gave up still trying to change the pawn into a queen. Rook-e moove, I'd say.
Good story but I highly doubt a GM misses this.
@@konroh2Sorry, I don't do opinions, just the facts. I was there when I was in the 7th grade. I think you were half a cell then or pretty close. NE ways, the GM just sat there and he went back and forth and had all the right moves up to the last queen exchange. Like I said, rook-e move. Yes, it did happen. Just saying.
@@nsatutor635 Good guess but 40 years ago puts me in the 5th grade. The GM can have an off day, but not seeing that P to Q causes stalemate, and not underpromoting isn't just a rook-e move, it's a simple 2 move sequence. A GM is someone who of the billions of people who've played chess is in the top 2000 ever. That's .0000001% of all people who've ever played chess. The GM may have been humoring you, decided not to figure it out just then, or something else, but it's far too easy a sequence to think he couldn't figure it out.
@@konroh2 As I stated earlier, it was "over" 40 years ago and had assumed that you were in your forties. You must be around 51, I assume. Backtracking, this makes your year of birth around 1973. OK, maybe you were just a toddler back then. The supposed GM made the same mistake at least 4 times, and he even backtracked making the logical moves from the beginning. He was definately an elder in his 60's I assume. After each confirmed correct moves, he gave up after about half an hour. I am also assuming that some other people had stated that he was a GM so I also assumed that he was. Also, you're wrong, kinda. Out of all "rated" players, there is about .85% chance that he/she is a GM. There are currently 170K rated FIDE players in the world. 1,444 are GM's. Just saying.
@@nsatutor635 We've probably grandmastered this debate long enough. Guess that puzzle pawned the GM, perhaps he needed a knight in shining armor, not knowing rook worked better than queen, perhaps he could have taken advice from his bishop? In any case, I crown you king.
This is the most famous chess study of all. Another famous study is Retí's pawn study (Kh8/Ka6). When I started chess as a child, someone showed me this position. I think everyone should know this position...
5:13 just promote to rook and no stalemate
the problem was not that they didn't realize they could promote to a rook. the provlem was that they thought it would still be a draw after the rook promotion since black has a rook too
This is a great old chestnut. I've seen it before, but not for a long time.
step 1: consider losing more than 90 % of your troops as your victory.
step 2: congrats bro, you win
Surely Rook d2 after pawn c7 threatens a perpetual
Thank you.... bloody amazing and such a strange way to pass one of my remaining evenings. But sorta fun🤗
Amazing. But I wouldn’t just resign as Black even if I knew the Puzzle. There’s always a chance White doesn’t and it’d be awfully difficult for White to figure it out on the fly.
Brilliant!
This is so beautiful. Thanks
I am at 1:19 only, and I don't see how the pawn can't make it. Unless you blunder the King away from the action, the rook is on a terrible square/row.
OK,--I did not see the options by 2:26. :)
But, by the time you get the King to a-4, there is enough moves (2 moves), for the rook to change to a column on the right and zip,-----------------------------------------------------------------------------------------------------------------------Oh---forget it. :)
4:55 very genius THrick
1:18 "to get the draw".. You meant, "to get the win" ?
Yes abysmal commentary
Super puzzle.
Underpromotion - my main complaint at work.
Start a business of your own.
Amazing!!!
Great puzzle.
Exact it is an endgame study. Also called chess study. The word "puzzle" is only colloquially correct. But ALL chess study composers in the world speak of endgame studies and never of "puzzles". Sam Loyd made great puzzles (Mate in 2, Mate in 3 and so on). But Retí, Liburkin, Afek, Didukh, Bron, Kaminer, Mattison, Rinck, Pervakov, Minski, Arestov and Kubbel and so on made chess studies. What is a chess study? A chess study is a composition with the demand: White on move wins, or White on move holds a draw.
At 4:36 can't you also just move your King up 1 square and guarantee promoting the pawn to queen without a stalemate?
No, black will just move his rook back to d1 (threatening Rc1+ after we promote) and we need to go back to c2 with our king. It will be draw by repetition.
Great puzzle
Avanzar el peon y luego devolver el rey blanco
Very genius puzzle for me men..
Wow! So clever!
Queen vs rook endgame isn't simple either
Don’t understand why promoting to a rook instead of a queen is the winner. Couldn’t the queen do anything the rook can do?
Because after the queen takes the rook on C4 to remove the check, it has the A2 square covered and the black king cannot move - creating a stalemate. This is a case where underpromotion is needed to give the black king a place to move so that a checkmate can be found.
I am not a player and these situations make my head hurt 😂
Unfortunately, queen is too powerful in this case
Queen helps the black pieces not to lose because of its strong power..
@@dmitripogosian5084you know a puzzle is good when the queen is too powerful to be promoted to
@@LiamWakefield Thanks for explaining! I didn't "get it" either! 😉
I don't even have an ELO rating, and this still was the easiest chess "puzzle" I've seen on RUclips.
Good for you buddy! Great job!

c7 keymove...
Isn't this a draw? Blacks first move should be R d2, then K b1. Black will give checks until the 50 move rule, or until the white king goes to the c file (in which it would take the pawn/queen after the king moves).
Never mind. White queen would move to the h file, then the white king would move towards the rook on the d-g files as the rook gives checks.
No, this is a chess study. It is art. It is a composition. And it is the most famous study composition. An absolut correct endgame study. And by the way: in chess studies the 50 move rule does not exist!!
@@petersiegfriedkrug I think you are wrong. The 50 moves rules apply, and also all rules of standard chess (3x same position, castle, taking pawn en passant, ...).
1.c7 Rd2 2.c8=Q Rb2+ 3.Ka5 Ra2+ 4.Kb4 Rb2+ 5.Kc3 and there are no more checks, so White will mate soon.
@@prestonotes I think he means in chess study, you can go as many moves as you can without capturing or moving pawn. Because of this, they can find all tricky moves and no worries to 50 moves rules. Do you know theres a position that white need to move above 500 moves to checkmate black? And its doesnt look like a elaborated set board. If we need to follw 50 moves rules, it wont be found.
cool!!
I don't see the reason why a rook was brought back instead of a queen. The queen has the same power and more. Where was the advantage in this case? It was not explained.
ok but why is the video 8 minutes

@@somerandominternetdude1 Nahhh, he explains other possible moves and speaks slowly as he's not fluent. You either just watch it (2x speed) or just skip it if you don't want to give him any possible chance to gain something out of this.
@@ronaldo19ronaldo exactly, ad revenue.
@@somerandominternetdude1you can't just say "exactly" and then go on to say something completely different from what the other person said as if that magically makes them have actually agreed with you
@@Pablo360able what he is explaining is literally him talking slower to gain ad revenue.
Easy draw for BL. Take it and go home.
Queen can do anything the rook can do so promote to queen. Same result.
Not same result, the queen does too much.
I must be a genius. This wasn't that hard.
This is a great old chestnut. I've seen it before, but not for a long time.
