Qf5+ Qxf5, d8Q Qc5. Qc5 forks two direct mate threats: Qa5# and Qb4#. White's best response here is to get the black bishop, disabling both direct mates. Qb6... would stop the mate threat temporarily, but black will then simply capture. After the black king captures the white queen back, it's king + queen vs king for black, which means white loses.
When ever I see a chess puzzle asking me who is in a winning position I will always answer white because of the conventions of the genre, just flip the colors and I would get it wrong ever time
For me the rule is whoever's turn it is, though if I can' figure out how they could possibly win, and think draw would be good in their position, the answer changes to draw.
5:10 What if we do Queen to c8 check? So that we can avoid both the bishop and the other queen so king has to move or block with the queen then there is no more checkmate threads and we can just get another queen and we win. +Edit : If black blocks with anything just take it then get another queen ther is no checkmates no worrys (But you need to look carefully first) or we can also keep checking black untill they cannot block and move then get another queen :)
Black can block with the bishop to c3 as well. You have to move the king to a2, after which there is a checkmating attack with queen to e5, blocking all the possible checks.
At 3:38, if the white queen went F5 and check the black king in an attempt to deflect the black queen away from D file, it was enough to get another queen and it basically defends the A5 square.. I'm not that good at chess since I'm a beginner so I don't have insight on what's best to play next..
3:37 I honestly don’t know why Queen B6 isn’t a good move for White. Defends from Checks, and if Black Queen goes for A2, you still have King B5 and Queen defending.
8:33 I am actually very curious is bishop to d8 an opportunity to win for black? I plugged it into the engine, but stockfish was kind of lagging or something, and it didn't see the moves that i considered as winning for black (I tried changing the depth, it didn't help much)
If bishop moves away at 8:00 then Queen to b3> King to c1 > Queen to b1 > King to d2 > Queen to b2 forces Queen trade and it's a draw. If bishop moves away at 8:15 then Queen to b1 > King to c3 > Queen to b2 > King to d3 > Queen to b3 forces a Queen trade or a stalemate. Correct if I missed something
Great question as that actually occurs in the main variation of the original solution. The video does follow the main line but finishes just a bit early with the perpetual check. The original solution goes 7.Ka1 Qe5+ 8.Ka2 Qd5+ 9.Ka1 (demonstrating the perpetual and taking us to 8:33 in the video), but then it continues with 9...Kd3 as you indicated, to avert stalemate. The study ends with 10.Qb1+!, which tablebases confirm to be the only drawing move. It's pretty hard to understand, but apparently other moves like 10.Qa4/Qa3+? would lose to 10...Bc3+!
What about rook to d6 check at the very start wouldn't that allow you to play pawn to d8 get a Queen, bishop takes, then take the bishop with rook and you're protecting f8 Queen upgrade?
At 515 of video... he says white queen to D1 check is only good option. You need to get the king to move off of the C column. Wouldn't queen to D8 do the same thing? It would force black to block with its queen or bishop or make the king move. If the queen blocks you simply trade queens.
I would be able to lose from both sides. The only move I got right was the Rook to g3. Other than that I fell in every trap you explained :D. I'm happy you take time to explain why certain natural moves does not work. If you did not I would not learn why they don't work. Great content!
Great, ignore tons of other white options like Qc8 at 5:50 to either exchange queens or pin the bishop and block the black queen. But I guess some interesting gambits is worth the price of white forcing a stalemate or draw. Brilliant.
I would do pawn check - bishop takes or I take him - rook check - take bishop, next pawn queen vs queen, it takes, I take. One rook left (but for sure, always depends on the opponent's move - if black sacrifies bishop and steps left with king -> threat)
Not really a chess player But... When the (whit) king was at a4 the queen was at f8 and pawn was at d7 Why not move the pawn to d8 That would make a threat to the black queen I don't know why he didn't do that! Can with good skills somone please explain?
Then it's a forced mate in 3: black Queen to c4, white King a3, black Bishop to c1, white Queen blocks at b2, black Bishop takes Queen at b2 - checkmate
I had found Rook pinning the Queen, then Queen takes, then promotion to a Queen was losing. But it never occurred to promote the other pawn to save the game.
Then it's a forced mate in 3: black Queen to c4, white King a3, black Bishop to c1, white Queen blocks at b2, black Bishop takes Queen at b2 - checkmate
What is wrong with this line? d8+ - K-C2 Q-c8+ Why do we need to sacrifice the queen instead of checking the king? If .... B-c3 then white responds K-a2, and black is out of checks.
At first, I thought it was obviously black to win, but then I realized white can go Rg3, pinning the queen to the king and black has to take or lose the queen, but that allows white to go f8 and queen and then it isn't so clear who will win
My reference was to after the last king move when Nelson says it is a draw I asked what happens if black plays queen to A8 as it appears that black king can hide behind its bishop exposing a discovered check
@@christopheryarnold2150 You said 'after white queen goes to b4', but there is never a moment when the black queen can respond with a8. If what you actually meant is 'after white Ka1 at 8:41', then white can start checking black, but without any apparent way to mate.
What about Qf3? As long as we keep white's queen from skewering our queen we can force white into a position with no checks and at some point trade the bishop for his queen and get a winning endgame.
I saw the first rook move and that was it. What an intricate position. Chess is the ultimate game of not letting your opponent know your next move.
But they know your next move and you know their next move and so on
Same I saw that
I saw it too
Me too
same
The way both players leave their pieces undefended and attacked makes it look like one of my games!
Lol
I play like that too i like to let undefended pieces to pieces that have more value or for better attak
At 3:40 isn’t Qf5+ possible because if queen takes we promote and get another queen?
Then Qc5 and black has mate in 4 because white can't stop both mate threat and has to sacrifice the Queen
Qf5+ Qxf5, d8Q Qc5.
Qc5 forks two direct mate threats: Qa5# and Qb4#. White's best response here is to get the black bishop, disabling both direct mates.
Qb6... would stop the mate threat temporarily, but black will then simply capture.

Black can block with the bishop to c3 as well. You have to move the king to a2, after which there is a checkmating attack with queen to e5, blocking all the possible checks.
After Black blocks there is another check on f5, and then only the queen could block so the black king has to move, not clear at all.
@@nonothik bishop c3 comes with check so white is just dead after a few more moves.
@@tobi439 Oh right of course, silly me!
@@tobi439
Black is out of checks after K-a2. No matter what black does, white either plays Q-f5+ or f8(Q).
On 3:39 couldn’t white just play QB6, it blocks all checkmates and allows queen to escape from black queen to A2. And allows wiggle room for promotion
at 3:31 you gave a line where the white queen is on f2 and the bishop blocks on d2. From this position, why does Qb6 not work to prevent checkmate?
If Qb6 Qc4+, Ka3 Bc1+ and mate next move.
At 3:36 can't we go to b6??? Please answer my question 🙏🙏
At 3:38, if the white queen went F5 and check the black king in an attempt to deflect the black queen away from D file, it was enough to get another queen and it basically defends the A5 square..

Qb6 Qc4 Ka3 Bc1 Qb2 Bxb2 mate
1. d8(Q)+ Bxd8
2. Rg3 Is equivalent, right?
I don't think so. Don't have the board up right now but I wanna say if d8Q then Kc2 is winning for black
4:50 king c2 is illegal
Why?
3:43 it's not over...push pawn to queen..it's actually a great move for white and simply defends opponents queen...is it..?
(@8:49) But what if black doesn’t take the queen with the bishop, but instead plays Bd8 (with the idea to swing it to f6)?
White forces a draw with Qc4+.
8:33 I am actually very curious is bishop to d8 an opportunity to win for black? I plugged it into the engine, but stockfish was kind of lagging or something, and it didn't see the moves that i considered as winning for black (I tried changing the depth, it didn't help much)

Correct if I missed something
Damn! There is actually a faster stalemate at 8:15 with Queen to c4 check
There is something i want to know. What, after White King to a1, would be the outcome if black move its King to d3?

very cool, but I still can't help but wonder what would have happened @5:43 if W played Queen to C8?
At 5:40, Queen to c8 with check might at least be mentioned.
What about rook to d6 check at the very start wouldn't that allow you to play pawn to d8 get a Queen, bishop takes, then take the bishop with rook and you're protecting f8 Queen upgrade?
Qxf7 is the problem, and now its a Queen versus Rook endgame
In 3:40 couldn't white Queen move to B6? I'm not an expert enough to know woud happened next but I think it can do something.
Black responds with Qc4+, which leads to a mating sequence.
3:35 what about c5? If he takes it stalemate
3:18 Pawn: bro, trasform me to a queen to defend all checkmates!
6:42 but cant you just play queen to a3 for white? to prevent checkmate?
nevermind theres queen to b1 for black ;-;
7:18 can’t you go to Qa3 which threatens the bishop and blocks all the checkmates and if black moves anywhere you can go for Qb3 check
Qd5 check, Ka1, Qd1, Ka2, Qb1 checkmate.
At 5:43 what if u move the queen to c8, one move the left and check the king that way
Bc3+
At 515 of video... he says white queen to D1 check is only good option. You need to get the king to move off of the C column. Wouldn't queen to D8 do the same thing? It would force black to block with its queen or bishop or make the king move. If the queen blocks you simply trade queens.

3:37 we can go there soo if Black take its gonna be a stalemate but if he wont we can get a queen
C5 queen
Excellent puzzle, very instructive!!
2:52 crazy thing about this position is it would be a draw if white did not have the d7 pawn... some of the lines are absolutely wild
Great, ignore tons of other white options like Qc8 at 5:50 to either exchange queens or pin the bishop and block the black queen. But I guess some interesting gambits is worth the price of white forcing a stalemate or draw. Brilliant.
Qc8 is a win for black after Bc3+. It's checkmate in 5.
At 3:24, what about moving the Pawn to get a queen? That would prevent the check mate for white, he would be in a winning position?
d8=Q Qc4+
Ka3 Qb3#
or
d8=Q Qc4+
Qb4 Qxb4#
Your suggestion provides black with checkmate in 2.
At 4:57 why wouldnt black just go queen a3 for mate?
7:20 How about Qa3? You can defend against the checkmate
Qa3 Qd5+
Qb3 Qxb3+
Ka1 Qb2#
I would do pawn check - bishop takes or I take him - rook check - take bishop, next pawn queen vs queen, it takes, I take. One rook left (but for sure, always depends on the opponent's move - if black sacrifies bishop and steps left with king -> threat)
Saw the first move
8:38 what if Qd1, Ka2 back then some random move was played to prevent repetition, it isn't clear who wins with the idea of same leveled players.
3:19 well what if you Queen the other pawn? That guards a4
Then black Queen to c4 would be mate in 2
Because of Qb3#
@@Blackn3t oh
3:43 White Qb6 prevents any mate and allows the king to go to b5 and run away.
If Qb6? Qc4+, Ka3 Bc1+ and mate next move.
Nice puzzle, I love seeing miracle draws like this
I had no hope of figuring this out on my own. It would take me days
You are my favourite TH-camr right now, keep it up
5:43 With the first queen check the king until you bring the queen closer to the king, then promote the second queen...
You don't have a good check though. If Qc8+, then Bc3+ counter check and it's mate in 5.
After getting the first queen, the chess program refused to evaluate the position.
I immediately saw the idea of skewering the Queen and King with the rook, as the Queen would be forced to take
Not really a chess player
But...
When the (whit) king was at a4 the queen was at f8 and pawn was at d7
Why not move the pawn to d8
That would make a threat to the black queen
I don't know why he didn't do that!
Can with good skills somone please explain?
The sublime beauty of chess is that the best move can be so unintuitive
3:39 what about queen to b6 tho?? Doesn't that just cover everything??
After Qb6 -> QC4+, Ka3, Bc1,Qb2,Bb2#
Then it's a forced mate in 3: black Queen to c4, white King a3, black Bishop to c1, white Queen blocks at b2, black Bishop takes Queen at b2 - checkmate
6:48 black blocks and there no more checks for us
Qf7- U didn't have to cut me off
0:14 pause there I mean pause and go there
4:01 I see: White sacrifices twice, to deflect the queen and the bishop. Neat.
hypothetically, what would be the sequence if black has next move?
I couldn't understand why we cannot lead black king away from C column by checking using queen on 8th rank
3:03 what if queen g2
nvm queen can block
Rook to G3 forces the Queen to capture it and you get a Queen promotion.
At 5:43 why cant queen go to C8?
Bc3+ protects. After that, it's a mate in a couple of moves.
At 6:40 why couldn’t the queen go to a3 to block the check??
How would it block, say, Qb1#?
4:50 why not queen to c8?
Bc3 protects against that and leads to a mate in a couple of moves.
3:36 How about Qb6?
Qb6 Qc4+
Ka3 Bc1+
Qb2 Bxb2#
Why not Qd5+ by black at 6:57 instead of Kc2.
Prepares a checkmate.
It is just impossible to play like that without the stockfish
You'll see that my mind is too fast for eyes
3:18 What if white makes a second queen here ?
d8=Q Qc4+
Ka3 Qb3#
or
d8=Q Qc4+
Qb4 Qxb4#
2:05
He sacrifices THE ROOOOOOOOOOOOK
Wait h 6 square is hanging time 3:39
I got the first 2 moves because they were examples of pins and deflection and were ridiculous moves so i figured they were correct somehow ;)
What about 5:42 d5 queen?
Checkmate in 1 - black just goes Qa3#.
Amazing puzzle Nelson!
I had found Rook pinning the Queen, then Queen takes, then promotion to a Queen was losing. But it never occurred to promote the other pawn to save the game.
at 3:40 cant we move the queen to b6?
After Qb6 -> QC4+, Ka3, Bc1,Qb2,Bb2#
Then it's a forced mate in 3: black Queen to c4, white King a3, black Bishop to c1, white Queen blocks at b2, black Bishop takes Queen at b2 - checkmate
What about Rook a6, threatening the bishop and a skewer to go d8 queen when it moves
Mate in 4 in favour of black, starting with Kc2 with the idea of eventual Qb2 mate.
What is wrong with this line?
d8+ - K-C2
Q-c8+
Why do we need to sacrifice the queen instead of checking the king? If .... B-c3 then white responds K-a2, and black is out of checks.
3:41
Did anyone else see that white has Q… b6. It doesn’t threaten mate, but I wonder if it’s a draw. Probably not.
Qb6 Qc4+
Ka3 Bc1+
Qb2 Bxb2#
Can u just move the queen 1 step at the left and u save your queen and check the king?
At what point in the game?
What if white played Qd1? Then you could force black out of stalemate and force a checkmate
At 8:36
Illegal move - white is checked.
What about black queen to h1???
queen to H1 check on the last part maybe iunno instead of capturing queen with bishop
What happens if white first move is Rook to D6 check?
Kc2 prepares a Qb2 mate at a later point
what about rook to d6
Black responds with Kc2, preparing a later checkmate with their queen.
8:17 what about if black plays Qd1?
Edit:nvm this also leads to stalemate, amazing position
If black plays qd1,white plays qb2 with check and then exchange queens and ultimately it’s draw
How much do you want to bet?
First move was easy.. after that was "Oh so that's the move" till the last move.
1:51 Rg3
2:38 ahh then you promote the d pawn to distract the bishop of the white king's area and not get checkmated?
And then he sacrifices THE ROOOOOOOOOK!!!!!!!!!!!!!!!
you brushed it of saying to many checkmate threats but couldn't the queen just move to a3
Which queen? At what point in the game?
Wait what about Rg8 isn’t that the best move if not how
What about Rook D6 then Pawn D8 to Queen
Checkmate in 5. Black just prepares a later mate with queen by going Kc2.
My guesses black because the black kings goes to c2,bishop c3,queen a3 well it's a draw so
Why did you ignore black's Qa3?
At what point in the game?
At first, I thought it was obviously black to win, but then I realized white can go Rg3, pinning the queen to the king and black has to take or lose the queen, but that allows white to go f8 and queen and then it isn't so clear who will win
