Love a good chess puzzle?
Watch the Puzzle Battle World Championship January 6th-9th!

Lichess is better. It’s free analysis,unlimited puzzle & got a lot room for improvement..
Rook f6 is also a check mate in 4 because white queen can come to h4 diagonal and rook can finish it off wihtout playing
Queen f5 you can make it a draw
i expected an invitation
Pretty sure game 6 between Nepo and Magnus was shorter than this puzzle
lmao
Still very nice explanations for low rated player like me 👌
Bruh
Nepo is a choker... no way ding misses Bxb4... that was so elementary, yet nepo missed it twice.
@@aaronchan1088 ok then you beat him if he's so bad
I love watching tyson fury solving chess puzzles

Hahahahahahha
😂😂😂😂😂😂
Check Mate! Ya Big Dosser!
I'm not gonna lie, that's funny
Imagine if one day chess becomes a solved game and they make a puzzle that’s just the starting position.
name checks out
That would be the ONLY puzzle at that point
Then chess would be as boring as Rubik’s cube
@@idocteur2975 Why on Earth would you find Rubik’s cubes boring?
I have a sneaking suspicion that chess will one day be solved, and that it will be a draw.
I want to see Hikaru making arrows on the second puzzle!
Cant wait 😂
I feel like if I had several hours (maybe a day) I could solve that first puzzle just through brute force calculation since there's a relatively limited number of variations given the remaining pieces and situation. That second puzzle, though, is something I don't know if I'd ever be able to solve. Too many possible movies that look like they're winning only to find out they're not because of some hard-to-see response, combined with a very counter-intuitive "computer-like" move to cap it off. Still, the logic is very pretty, just incredibly complex and way above my 1700 ELO paygrade.
I'm 60 ELO and only got the first knight move right lol
ASNOJLFADNJKLDANJKLASF ITS A MATE IN 4
Took me almost two hours to solve the second puzzle
@@patstaysuckafreeboss8006 u didnt solve the second puzzle the correct way
@@Wtahc Yes I did. It’s just a long process of elimination.
"I encourage you to pause the video and try to solve it" spends a minute trying to figure out which colour I am
Second one felt more like a "position" than a "puzzle", if you know what I mean. As Sam said, it's not the kind of thing you really figure out ahead of time step-by-step. You just keep reacting and trying to find the best move. (I did not find the best move each time, obviously).
First one wasn't that bad. Just had to figure out which Queen check was right and why. There weren't that many options.
The main issue with the second puzzle highlights why it's difficult to translate puzzle expertise to the game. Black's counter play that saves the game is more difficult to find than White's attacking moves following black. When we are in a game, we are naturally biased to finding our own moves over finding opponents best moves
One day there will be the puzzle: 1e4 white to play and win. (Just kidding with perfect play it would probably be a draw right?)
@@JBHACKSAW It's not just a "bias". Sometimes it's mentally exhausting and just practically impossible.
Even the strongest players often fail to see relatively short and simple lines during competitive matches.
@@JBHACKSAW personally I liked the puzzle on the point that it felt more like a position
black's counter play tbh were the only moves so practically, they would go for the line even if they weren't sure it saved the game
but for puzzles in general it's true
You can watch Magnus Carlsen get puzzles wrong because he's just using intuition
9. Qxh8 - Stockfish 12 -at depth 42 evaluates postion to be a mate in 31 moves ! That means is a mate in 40 puzzle
How is mate in 31 a mate in 40?
@@RoZaxTheGreat because Qxh8 is the *9th* move of the puzzle. Thus after that is 31 more moves for checkmate, thus mate in 40
@@jamesknapp64 It’s not all forced though.
@@jamesknapp64 no?
First-class explanation, Mr. Copeland! This was very instructive--reminding us to look for quiet moves, to consider _all_ legal responses of our opponent, to not be greedy and cash in early while attacking, and to stifle our opponent's counterplay.
Copeland easily one of the best to make these breakdowns!! Thanks for all you guys do!!
I actually found this mate in 4 after about 10-15 minutes of thinking. But the last position is just a nightmare
By 3:53 you can play rook on f5. Only the pawn will be able to take the rook. After pawn takes, you play queen on g7. King only can move to h5 and than it’s pawn checkmate. Beautiful rooksec.
Lesson in first puzzle reminded me of a simple clear memory of a roommate hollering frustration playing on FICS in the mid 90s. Dan: “I can’t figure out how to keep my tempo and looks like big problems” me: “gotta quiet move?” Dan “thanks!”
hahahahaha
"pause the video and solve it"
how many reincarnations do I get?
The first one was inutuitive and easy but the second one was quite impossible
How do they rate puzzles? The first was quite doable. The second was insane.
I believe they rate puzzles just as if the puzzle and the solver are opponents in a game. If the solver solves it, then the puzzle loses, and its rating goes down. If the solver fails, then the puzzle wins, and its rating goes up. There is no person judging the difficulty of the puzzles. Sometimes puzzles with relatively easy solutions can have high ratings because a lot of solvers are too hasty and think they have it solved when they don't.
@@mychessnotebook8653 The rating of the first puzzle would probably be much lower if the participants were allowed to see the rating before attempting the puzzle.
@@andy02q You usually get puzzles as a strong as your rating, so the solvers knew it's a difficult one
I found the king to G4 from the start so I think I'm a GM LOL 😂😹

@Priya Sengh no..

@@David-jc3ub yeah lol
the automated captions are insane 🤣
True 🤣
So in the 2nd puzzle, after 1.Nd6+, Black presumably has choices in where he moves his king - either to f8, d8, or (as discussed in the puzzle) e7. Also after 2. Nxe5, it is not clear why black is forced to take KxNd6.
That was pretty much explained in the vid. He has to go to e7 in order to be able to take on d6, otherwise white has got back most of his material, will pick the N on h1 up and even be material ahead while retaining an attack. Easiest to check with an engine though, the position is so abstract it defies verbal commentary. Suffice to say not playing Ke7 and Kxd6 is about -10
@@JamesColemanChess no, Black can choose between Kf8 and Ke7
The first one was a cool puzzle. The second one is a Stockfish vs Lc0 recap.
3:50 what the hell did he just say?

That second one doesn't look like a puzzle - it looks like the analysis of a Fischer or Morphy game lmao. The epitome of "when you see a good move, look for better."
I literally solved the first one, including the quiet move. Theres no way this is the hardest puzzle. Guys like Hikaru could solve this in 10-20 seconds probably, at most.
I am rated 1100 btw which is reallly low. So I am really surprised this was here.
yea it was kinda easy
I found Qf7+ (I just saw it before Qf5+), but was too lazy to calculate till the end and just watched the video
Learning how to solve 3953 rated puzzles while i cant solve the 1500 rated ones
The second one is just a game position. It's a puzzle in the sense that all chess games are chess puzzles.
The point of puzzles is that you have to find only moves. The puzzles end as soon as you have more than one winning (or drawing) option.
That's the incredible thing about puzzle 2 and what makes it different from a normal position: EVERY SINGLE MOVE you have to find is the ONLY winning move.
@@fritzzz1372 I see. Might be my own oversight, but it wasn't clear at all to me that this was the *only* winning path, just that it was the best path. It seemed that many variations were possible at several steps.
@@brianstephens8337 These are" only moves" to blacks best defense. If black plays a subpar moves, than white can has different/multiple winning moves.
@@fritzzz1372 1. Nd6+ Ke7 2. Nxe5 Nf2 3. Qd4 Qc7 4. Nexf7 Rf8 5. Qxg7 Rxf7 6. Qxf7+ Kxd6 7. Qf4+ Kc6 8. Bb5+ axb5 9. axb5+ Kb6 10. Qxf2+ Kxb5 how about this line hmm
as a 800 noob, this video was very well explained!
Me: Cracks first puzzle faster than Sam could say a syllable
Also me: Misses mate in 2
i didnt know tyson fury was into chess too, amazing
(before watching the video)
Qf5+
If g5: Qh7#
If kh6: Rxf6+ gxf6 Qxf6+ kh5 g4#
Can't be that easy right? I must be missing something.
edit: LOL
It's going over my head.
1st one should be rated around 2000-3000. It's way too easy
me as a 1k rookie was scared to hear that this one was too easy
It's definitely overrated, but it's only easy if you don't rush when trying to solve it. If it was blitz and I had less than one minute left on the clock, I'm a bit embarrassed to say that I probably would have played Qf5+ as it was my first instinct when looking at the position.
its not easy because its just really tricky. when you dont think much enough on these puzzles you can just blunder your queen move or smth like that.
At 2:27, isn't it over ?
If white moves pawn to g5 check, I only see 2 possible moves for black. King g7 and king h5.
On king G7, you have rook f7, leaving the enemy king to go to h8 or g8. H8 is mate in 1 due to queen c8. G8 is mate in 2 with queen e6, queen c8.
As for h5, you have g4 checkmate in 1
The second puzzle was already impossible and then finding out that the killer move was the silent rook blocking in the counterplay of the queen makes it literally impossible
Some great puzzles! I get confused by ones I just don't practice enough. It's like being awake and really tired at the same time.
Solution is
Qg7+ Kh6 Rxf7+ g6 Qf8+ Kg5 Rf5+ gxf5(only move) Qg7+ Kh5(Only move) g4# NVM
The first puzzle took me 40 mins to solve but after I solved it,it looked quite simple, you just needed to calculate 3-4 candidates and all of them were logical moves.
Well, exactly as you said it, thought I found forced mate in puzzle 1, pawn move tripped me up
i wouldn't be surprised if there's a 4,000-plus rated puzzle later this year.
Possible, but the limiting factor is there are many puzzle solvers who practise and memorize all the puzzles before solving them in rated mode.
at 12:50 i thought it is end of the vdo
first puzzle is trippy in deed. i spent 5 min looking at it and didn't even notice first check available. that said the ideas after you see that check are fairly simple. its some sort of square blindness
5:49 OH yes... I remember this puzzle. I needed one hint but besides that found it quite enjoyable and a breeze
Elaborate
Can't believe the Stockfish 16 solve this puzzel in 4 moves!
Moves: Qf7, g6, Qxh7+, Kg5, Qh4+, Kf5, Rxf6#
First puzzle i say "wow"
Second puzzle "whattttt???" maybe it's like how to revenge the rook 😂
I'm proud that I guessed the first check correctly.
1/3 chance realistically, nothing to be proud of unless you calculated. I’m like 1.5 elo and I guessed correctly too
@@cyanhallows7809 Well I hope you never find pride in the little things of your life, either.
@@PistolShrimpPimp I don't, no worries pal. Only things I work hard for
On the first puzzle i calculated 1.Qf7+ Kh6 2.Rxf6+ g6 3.f8+ Kg5 4.Rf5+ g×f5 5.Qg7+ Kh5 6.g4++, where did I messed up?
You messed up on white's move 3. It should be Qf8+, but we know that was only a typo, so actually YOU SOLVED IT !! Same thing I got when I did the puzzle.
@@SpaceCadet4Jesus hahahha my bad, thanks for the response!
@@santiagocontte622 Bad news. We both screwed up on the last move. If g4+ then black f5xg4+ and now white is exposed and loses. I had to put it on a board instead of my flaky mind. 🤷♂️
So happy I solved the first puzzle after like 5 minutes of thinking
Huge difference between the two puzzles in difficulty
Thank you Sam for these solutions to the puzzles, you helped a lot.
I’m ~ 1100 in rapid and ~1900 in puzzles, so I don’t know why I spent half an hour trying to solve them
I actually found the brilliant move on the first one, but I did queen f5 check instead.
I thought pg4 was the move because if kh6 then qe5 defending mate and also threating mate in one but missed that he had pg6
Whats a p
@@justusschoenmakers8987 pp
Btw, pawn notations dont have a p in them. Example, pg4 you say g4
Those captions are funky
The second game is not a puzzle but a game position.
Love the background music
First one is super easy if you assume it's blacks move :)
The first one is quite easy but the second one is incredibly hard.
I found all moves until the quite move at the very end. I thought about moving my king closer... But at the very beginning I missplaced the black rook, it was on E2. And with this the quite move leads to forced checkmate by black. Damn.
I still have the second puzzle though, I'll try to solve it later
I don't know what the solution would be here, but a very human sequence of moves is g4+, worst move for white is then Kh6 which leads to a queen sac. Qg4+ looks good but the king slinks away by wandering to f2.
g4+ is bad if Kh6 though since that leads to a queen sac followed by a not quite guaranteed rook+pawn checkmate.
So I'm gonna say the best move is Qf5+, forcing Kh6 as the only legal response, followed by a rook sac on f6, recapturing with queen leading to check mate?
On second thought that idea does not work either, that leaves Qf7+ as the only possible move left.
To elaborate the full sequence would be ...
Qf7+, g6
Qxh7+, Kg5
Qxh4+, Kf5
Rxf6#
No?
Qf5+ doesn't work because best response leads to a guaranteed draw, something I overlooked initially. (Qf5+, Kh6, Kg4, g6 ... leads to draw, the rook sac is by no means forced)
Bruh in the first puzzles I was like gotta go Hikaru mode with 100 arrows and it was just a mate in 4…
You said to pause the video without saying whose move it was.
7:52 why because the queen still covers the square where the king attacks the bishop and because of check the king must move so you win the rook for free
got the idea on the second puzzle but only got 3 moves in a row right. queen to f4 was hard for me to see at first.
I got every puzzle correct in the first try except the last one!
Well, I'm happy I actually solved the first puzzle from start posistion.. preferred Qf7+ and had saw the Kg4 idea.
Second puzzle I've spent like an hour lol, saw all the lines going one move at a time ((btw 12:22 Nc6+ Kb6, a5# better, always mate with pawn!)) and found the correct move UP until 13:11... gg engine move. I considered ideas of enclosing the queen, but only to discard them because there was no way to either mate or win the queen. Such a long puzzle simply ending in a winning posistion with equal material is a bit disappointing!
Honestly I feel like Puzzles are surprisingly easy compared to actual games. Tactics might just be easier than Strategy but I paused the Video and managed to solve these puzzles on my own when I really have no business solving them as a weak hobby player.
For the second one I thought the exact way he did recommend not to go for.
so its an equal position at the end?
Equal material...yes...but not an equal position at all.White has a lot of threats while black has no counter play,even though they have the same pieces
0:30 well perhaps htere are still lower rated ones that are harder
Wait but isn’t the first one just: pawn g4 - king g5 - queen f5 - king h6 - queen h5?? Or am I missing something
should be Qf7+ Kh6 Kg4 Rh2 Rxf6+ gxf6 Qxf6#
Black does not have to play Kg5.. can play g4+ Kh6 g5+ Kg6 Qxe5 Rd3+ Qg3 Qc3 Qxd3+ Qxd3+ Kg2 Qxa6 Kf2 Kxg5 Kf3 Qe6 Kf2 Kf4 Kg2 Qe2+ Kh1 Kf3 Kg1 Qg2#
This was a wonderful video, great work!
Isn't the "Matein X move" critical information to solve a chess puzzle? Just not disclosing how many moves is required make things even harder .... Worse, some puzzles are considered 'solved' even if there's no mate, so the 'solved' criteria is kinda essential...
The point of doing tactics is to improve what you’d do in a real game, saying there’s mate in 4 makes it significantly easier as you can discard anything that doesn’t lead to mate by the 4th move
@@adaelasm6467 Ok so in 'tactics', if there's a mate in 4, but you find a mate in 6 or 10 moves, you've solved it successfully?
@@literalghost929 usually that will be considered an alternate solution and you still have to find the fastest one if it’s a “‘mate in X” puzzle
@@adaelasm6467 And how do you know if there's a fastest mate? If there's no fastest mate/win, you could be wasting your time looking for a fastest solution when you've already solved the problem ...
And even worse, as I said, there are some puzzles where it's not even a mate, it's just a 'winning position' or material gain, so if you don't know what you're looking for, you might be wasting your time trying to find a mate in 3/4/5/6 moves, when none exist!
@@literalghost929 yes, that’s how real games work lol
Doesn't Qf5+ Kh6 Kg4 g6 Qf6 Qb4 Qh4+ Kg7 Ra7+ with checkmate following by the Queen work?
Instead of Qb4 (or Rf2, which loses as well), Black has Qb7! from where the queen protects against Qf8# because the Qb7 can interpose on g7. Qf8+ Qg7 Qf4+ would be a nice mate if there weren't a pawn on e5. White needs to get rid of that pawn first with Qg5+ (instead of Qf8+) Kg7 Qxe5+ Kh6 Qg5+ Kg7 Qf6+, but then the black king no more goes to h6, but to g8. This entire line looks so close to winning for White, but actually it isn't.
@@friedrichvolkmann
Thanks for analysis!!
Wouldnt it be better if you moved your queen to D4 in the 2nd puzzle (speaking of the first move of course)?
I just have 1900 rapid but im proud i find the first one fast
I found the “3900” puzzle rating a tthe beginning in 20 seconds, my puzzle rating is 3000😎
0:45
Ummm…….
Is part of the puzzle here also knowing white to play? Black to play? Game to draw? Who to win?
What's wrong with 1. Qf5+ Kh6 2. Kg4 threatening Qh5++ ?
I solved the first puzzle before you explained it!!!
why is jordan peele in the thumbnail?
For the first puzzle, I saw that after Qf5...Kh6, Rxf6 doesn't work. But the move I calculated after Qf5...Kh6 (1:39) was Kg4. Now Qh5 and Qg5 are both mate in 1 threats, and black has no checks. Struggling to see how white isn't winning. g6 in that position must somehow be holding as well, but it's difficult to understand how.
If White played Qf5, White gets mated with Rh2#
@@nooneliterallynoone1962 Qf5 is check!
g6 kicks away the queen and prevents any other checks. You cant keep up the attack
@@NormalTheBand No, g6 doesn't kick away the queen. The queen eats the f6 pawn and threatens Qf8# or Qg5+ followed by Rxa7+, mating. The problem is that Black can defend with g6, Qxf6, Qb7! See my reply to John Dale Steven Cunanan. This line (and particularly the difference between 1.Qf5+ and 1.Qf7+) should have been explained in the video.
First time I've seen the first one I thought it's easy but trying to do it after few days with little bit of memory got lured by all wrongs paths & it's gonna happen to many if faced in puzzle rush.
Ahhhhhhh, I thought g4+ was the answer to the first puzzle. I didn't look close enough
g4+ Kh6 g5+ Kg6 Qxe5 Rd3+ Qg3 Qc3 Qxd3+ Qxd3+ Kg2 Qxa6 Kf2 Kxg5 Kf3 Qe6 Kf2 Kf4 Kg2 Qe2+ Kh1 Kf3 Kg1 Qg2#
I don't understand how the 1st puzzle is 3952, I mean I feel it should be like 3295 if you shuffle up the numbers. And Btw, Qf7 was the most natural to me, not Qf5
I can't imagine the first puzzle is rated more than 1800-2000. I'm only ~1100 and found the first two moves pretty easily. I didn't calculate all the way to the end as I felt that once the white king was safe then finding the mate wouldn't have been too difficult!
The second puzzle is a masterpiece though! I had 3 candidate moves in mind and I'm glad one of them was correct - my other 2 ideas just gave black forcing lines to simplify. Though, the move that was correct was the one I felt I couldn't find a continuation for!
Excellent video Sam. Described and explained everything clearly and concisely and didn't rush through it.
the first puzzle is that high because its just very tricky. ofc if you will think much more on this puzzle and not do anything that looks like true then you will solve it. its just that theres a really tempting moves. second puzzle is not that hard tho. i got 3 moves in a row right. queen to f4 was hard to see on 4th move tho. but these puzzles are simillar in a tricky way cuz in the second puzzle we want to castle or move knight to fork too. really tricky puzzles.
I watched the beginning three times and didn't hear you tell me which side has the move and the objective. Then you say to pause the video. Did I miss something?
Black obviously has mate in 1 so naturally you can figure out who's move and objective is it
Can the second one even be considered a puzzle given the sheer number of possible moves?
I am just 800 and I actually saw Kg4 lol (in the first puzzle)
but I didn’t see the first check :(
I got the first puzzle completely!!
at 3:51 why can't white play rook to f5 and pawn has to take so then play Queen g7, the king has to go h5 and then move pawn g4 checkmate?
Funny that several people have been asking that question. Pawn to g4 is no checkmate because the black pawn which had just eaten the rook on f5 can then take further on g4.
@@friedrichvolkmann ah right, thank you for clarifying. It's really hard to imagine in my head
I solved it in 10 seconds the first one
Great video!
I don’t know chess study rules but is it assumed you can castle? If not Rd1 does not seem to win since Qe3 Be2 Qg3 forces Q exchange.
The right to castle is assumed in studies unless the oppositite is either explicitly mentioned, or implied by retro-analysis. There's still the dogma that every study needs to be derivable from the starting position of standard (i.e. non-fischerandom) games.
@@friedrichvolkmann Thanks for info!
Great video. Loved it
yoooo tyson fury big fan!!!
I solved every puzzle in less than 10 seconds so pls give me more difficult puzzles
The first one was easy. I figured it out in two minutes on my first attempt. I even missed the wrong Queen check you showed first. I just slowly found the elements needed for the right moves. I don't think that puzzle should be over 2400pts.
