2:50 I'm not sure that KB6 was the only winning move. I was hoping you would explore the move I would have made, which was NF4. Now the black knight cannot fork the king and pawn, and we're back to were we started. Am I missing something?
I see White winning with the first move. He just pushes the pawn to a Queen , gets check on promotion slides to B-8 when the King moves, then takes the pawn on B-7 and mates. If black moves first, Knight x g- 5 pawn and white can't win. There is black knight to g5 which leads to a fork, but you move K to b6 and again Black can't win.
Third chess player: White loses on time trying to find the mate
Fourth chess player: White loses on time
Germaphobe that was amazing
Fifth chess player: White draws because he doesn't know how to checkmate.
Not after watching this video.
sixth player: white wins because black saw the mate and left out of anger
At 2:49 why couldn't white do nf4? Moving the knight to a square where it stops the fork and gives protection to the pawn(even though the pawn doesn't need it).knight to f4 also threatens the pawn on d3. If the knight can capture the pawn, black can do Ne6 but it would be a check instead of a fork.
9:05. Qg1 to block on a7 wasn’t mentioned. But of course, there is also a checkmate: Qxa3+ Qa7, Qf8+ Qb8+, Qxb8#
I found Qc4, but only because I was worried about checks along the C file
Same
I found it because i was thinking to cut off the kings escape lol
I overcomplocated it way too much
I found that too, but not Qc4-c3. I thought Qc4-c5 wins too, but it does not. Black plays Qd3 and has access to a6.
Same
I feel like Qc4 is worthy of its own study. Insane position, thanks Nelson!
09:13 There's also Black's resource ...Qf1, aiming to block the check with ...Qa6, but of course White just goes Qxa3+ and Qf8+ etc. anyway (sorry if this is obvious). Black's other try, ...Qg1, is similar.
How is Qg1 similar? Me and my 500 elo looking and don't see a way white can threaten checkmate with that.
@@gibbers2
09:13 I'm seeing 1 ... Qg1 2 Qxa3+ Qa7 3 Qf8+ Qb8+ 4 Qxb8++ 1 0; what am I missing? Cheers :)
@@rogerkearns8094 You're missing that I'm a shortsighted fool lol. For some reason I had it in my head that the queens would trade if they did that.
@@gibbers2
Nothing foolish here, we're both analysing in our heads, everybody misses things. Best wishes. :)
Was going through the same line helped me a bit
So thank you:)
1:36 Why after NG5 can't you counter with NF4, controlling E6 and preventing black's knight from interrupting your pawn-promotion-with-check plan?
I thought the same thing, after checking with engine I found out that by playing Nf4 you no longer control the f6 square and black can stop you from queening with Ne4 then Nf6 guarding g8 and winning with his extra pawns.
@@secretfish6646 Ah ok ... thanks, makes sense. Actually still a little tricky -- there are a couple resulting variations I see -- but they are all too slow. Interesting position.
Why can’t you just sacrifice the queen
@@idoiticidoit5678 If you sacrifice the queen you will never win?
I've noticed that for a lot of puzzles, using the opponent's pieces to blockade the attacks of their long ranged pieces and/or blocking their king from escaping are very important, and sometime more important than having more pieces
I always love the puzzles that you show us. I almost solved this one all by myself, even though I'm new to chess.
At 8:10 I liked Qc5 better than Qc3 with the same idea. And then as soon as black plays Qd3 guarding a3 and a6 I realize I threw the game as usual.
Same happened to me 😆 lol
Sometimes I put these puzzles in the background cause it's soothing listening to Nelson talking through the problems lol
Facts😂
9:20 Black still has the relevant resource ...Qe2, to interpose on a6 against checks. - White still checkmates via Q:a3+ Qa6, Qf8+ Ka7, Qb8+, though.
Thats a tricky one. Requires a bigger brain then I have. Great video Chess Vibes♥
One of the best problems ive seen. Ive never seen problem with that many cominations and unexpected moves, but i think beggining is the most beautiful.
What about instead of moving the king to b6, white moves the knight to f4 which prevents the black night fork on e6? Wouldn't that be a win for white as well?
The black knight will instead move to e4, then f6, and g8. It just has to get in front of the white pawn. White can try to use their own knight to guard f6 by moving to h5, but black gets a really creative attack by going to d6. if white pushes the pawn, they get forked on e8, and if the king captures on d6 then black will promote the d pawn with check, and win from there.
@@linguotgr 1:44 why white knight cant go to f4 prevent the fork?
We can also do knight f3 and don,t alow any of the pawn to become a queen because we will cature the pawn
You always have the best puzzles!
Always bet on white!
2 extra pawns can't help black win is super fascinated! It proves that tempo is important than material!
Not always. But in this particular case yes, tempo is more important! 🎶
You missed a variation...after White plays Qc3, Black could play Qf1 trying to block, but you anyways play Qxa3+ then after black plays Qa6, you play Qf8+ with check, then black moves Ka7 and you've Qb8#
after 1.g6, Ng4, doesn't 2. Nf4 stop the fork, permitting the pawn advance and the original continuation after g7-g8-Q ? (supposing a black pawn move in the meantime.)
For instance:
2...d2
3.g7,d1-Q
4.g8-Q+,Ka7
5.Qb8+, Ka6
6.Qxb7+,Ka5
7.Qb6+,Ka4
8.Nxd3 and
9.Qb4# follows whatever black does.
NOPE! as @secretfish6646 pointed out:
I thought the same thing, after checking with engine I found out that by playing Nf4 you no longer control the f6 square and black can stop you from queening with Ne4 then Nf6 guarding g8 and winning with his extra pawns.
Such a good explanation, thank you
1:30 - Well said.
ive been exponentially getting better this past month and was actually able to solve this one on my own
6:04 we don't even have to take their queen. We just go Qc5+. If Ka6, Qb6#. If Ka8, Qa5#. And finally, if b6, Qxb6+, Ka8, and finish them off with Qa5#, Qa6#, Qb7# or Qb8#.
At the end there, what happens if black plays qf1 instead of qa4 planning to block the white queen on a6 while being protected by the pawn on b7?
Yeah was thinking the same pls notice this comment guys
Qxa3+, Qa6, Qf8+, ka7, and white checkmates with Qb8 because the queen blocks his only escape route
Could you not play Nf4 instead of Kb6? Would stop black from being able to play Ne6.
I thought the same thing, after checking with engine I found out that by playing Nf4 you no longer control the f6 square and black can stop you from queening with Ne4 then Nf6 guarding g8 and winning with his extra pawns.
Quite thorough analysis of a cute little study, thanks!
Amazing, somehow i saw almost every move
Are you a good chess player , a good guesser or a psychic
I saw every move as well, and only one of them was the wrong reason. (Also, I'm a 900) (edit: i missed one, thats it)
8:16 there is also a Qf1 that leads to a draw from black.
it’s not, because after Qxa3+, Qa6 to block, the white queen can M2 by swinging back to 8th rank and checkmating with Qb8#
thank you for this wonderful
videos
Is there a difference if we play Qc5 instead of Qc3?
Yes, 8.Qc5? allows Black to draw with 8...Qd3! 9.Qa5+ Qa6, and now the white king prevents 10.Qd8+.
At 9:23 what about queen to e2 or f1? That sacrifices the pawn but let’s the black queen move to a6 when it’s defended by the pawn and stop the white queen from checking the king and leading ultimately to a draw?
9:12 antoher variation.
Qf5, stop stop mate threat in a file. Then Qxa3 Qa6 blocking check Qf8 check. Ka7 Qb8#
Queens don't move like that. Neither queen can get to f5 at that point.
5:34 put the queen into a "zugzwang". Did not know that this german word is used in english. Love your videos, have a lot of fun with them!🤗👍
7:55 white is actually threatening Qc5+ and a5 #
1:35 Here, I wondered what would happen if white played Nf4 instead of Kb6, since that also prevents black's knight fork. Looking ahead, I think it might cause problems since black would likely respond with d2 and with the white knight no longer guarding the b4 square, a checkmate is no longer straightforward.
I found the mating pattern as soon as the black queen moved to a4, so proud
You missed blacks queen to f1 to prevent checkmate after whites queen to C3. Because black can then move the queen to A6 to block the checkmate making it merely check. I know this still doesn't prevent a checkmate when white moves the queen H8 followed by queen to b8 BUT it is an option you overlooked for black.
5:09 finally I found a move before he tells it
9:14 there is the variation queen to f1 or e2. The result its the same, but ye...
At 9:00 what about queen f1 (yes, queen e2 also works
Qc3 Qf1
Qxa3+ Qa6
Qf8+ Ka7
Qb8#
My favourite Chess channel 👏👏👏
I got the critical moves king to B6 and later Queen to C4 correct .
at 9.16 you could move queen to F1 and it would prevent both possible check mates and come out as a winning game
Qxa3+ is winning for white because after the queen blocks on a6, the queen swing to the 8th rank with check, and after ka7, Qb8 is checkmate
I somehow guessed king b7 and queen c4
9:20 does Qf1 work? And then Black Just blocks?
Qxa3+ Qa6
Qf8+ Ka7
Qb8#
Surprisingly I actually got the moves right 2nd puzzle I manage to find moves on my own
After Nc7+ and NxN, just push g7 rather than KxN
What about a king move that controls the square where the black knight wants to go?
Me: trying a way to sac the queen, me 3 seconsüds later: its my only piece
I actually found Qc4, kinda proud of myself lol
Qc3 isn't hard to find. There aren't many good moves white can do there either. c1, c2 and c6 are all defended and only leaves c3 and c5.
6:14
...Qi1 check!!!
But after move ... b6 and Qg6 why can't play Ka6?
What about q f1 instead of qa4 for black
8...Qf1 9.Qxa3+ Qa6 10.Qf8+ and mate next move.
"Why would you choose c4 than any other square?" BECAUSE THE BOMB HAS BEEN PLANTED
7:45 🤨🤨🤨🤨🤨🤨🤨🤨🤨🤨🤨🤨
Can't say how amazing is this
5:08 I GOT THAT CORRECT
but when the queen moved from controlling the white squares to the dark ones she couldve moved to b5 and its mate in 1 and black also cant stop it
After Qc3 black can play Qf1...and then block checks with Qa6
Qc3 Qf1
Qxa3+ Qa6
Qf8+ Ka7
Qb8#
1:39 knight to f4
What about black queen going to g1, isn't it preventing all checkmates with the following move g7
9:18 what about black queen to f1 to be able to block on a6 protected by the pawn?
8...Qf1 9.Qxa3+ Qa6 10.Qf8+ and mate next move.
9:00 can't blacks queen move to f1 or g1 to block check on f6 and g7?
Qxa3+ Qa6
Qf8+ Ka7
Qb8#
OH THIS IS ACTUAL POKÉMON?!?! I thought it was fan made until I looked at the channel. Super cool, was kinda creepy.
5:00 queen to g5
I like this puzzle. But I don’t think the position at 5:55 is quite a zugzwang. Usually zugzwang is when all moves are bad while being able to pass your turn would be better. But white still has mate in 3 with Qc5 even if black could pass.
Yes correct! But most people use Zugzwang in this manner too. Ignoring the pass condition.

What if black king moves down instead of moving the pawn first ?
I felt like a genius getting qc4 instantly
At 8:15 why can’t you go Qc5 instead of Qc3?
Black responds with Qd3, which would be a blunder in the line shown in the video.
2min48: I don't agree, king to D7 is good too. The king eat the knight if he tries to get the pawn, and the coast is still clear for the Queen to check when summoned. Only the A1 black pawn promotion is dangerous, but then the game opens up a bit but yes it isnt as well controlled as your example shows... But there are still some dangerous moves that can be done!
If white Kd7, then black can safely promote the pawn on the a-file, escape the g8=Q+ checkmate, and force a draw.
so the real lesson is that queens belong in the center of the board as the queen on the edge did not enough options to defend or attack. Also that the most advanced pawn wins in pawn races.
1:46 I'm wondering why knight to f4 isn't a move here for white. It controls the square that the black knight wants to go to in order to fork the king and pawn
9:16 I also don't immediately see why queen to f1 doesn't work here as it'd allow them to block the check while being protected by a pawn.
At 9:16 if black plays Qf1, white plays Qxa3+, forcing black to play Qa6. Then white plays Qf8+ and ultimately Qb8#.
At 1:46 if white plays knight f4 black plays knight to e4 which ultimately prevents white's pawn from queening with knight f6 and will allow black to push the A pawn and win the position
at 9:15 cant you just go to Qf1 cause if you try the same idea the queen can just block and its defended by the pawn on b7
Qxa3+ Qa6
Qf8+ Ka7

@@thetaomegatheta thank you
Okay what if black is tricky and under promotes to a knight?
Then it's even easier for white
How do we send these chess ones to you.

5:04 i saw the correct move, but it was the wrong reason lol
Great puzzle. I probably would resigned in most all those positions because I wouldn't have known how to put the queen in zugzwang.
9:00 what if black moves his queen to e2?
It can stop both of them
Qc3 Qe2

I knew the last move wohoo ☝️💪💪👑
at 9:27, can black just move their queen to g1, if white queen checks just go to a7 and block the check
Fails to
1.Qxa3 Qa7
2.Qf8+ Qb8+
3.Qxb8#
9:14 what abaut g1 ?
Then white can take the pawn with check and after queen blocks f8 check and queen is forced to block and then white takes queen with checkmate
@@MessLeadingProgramming oooh thanks
Qf1 is also a try, but similarly Qa3+ Qa6 Qf8+ Ka7 Qb8#
I found horse to g7 to stop the white pawn
Wait on the last puzzle why couldn’t the black queen just go E2?
At what point in the video?
8:08 what about Qc5
Edit: nvm, the answer is, black can play queen d3
If I were black after g6 I would not play Ng5 but Nf4. Then if white takes my knight I immediately start pushing my d pawn to promotion and now whites knight is distracted quite far which may be sufficient for my king to escape from checkmate (I did not analyze it deeply so I may be wrong). Otherwise I can take white pawn or white knight with check
Exactly my idea. But then the almost same positon happens. Right after promotions on both sides white plays Qc4, the same zugzwang happens. Only this time white has an extra knight.
You're right. Qc4 is a killer move. This knight sacrifice is hopeless
what if black queen go to G1? In 9:19

C4 is explosive
Is Qc5 a twin for Qc3. Both moves seem to work.
Against Qc5, black can go Qd3.
Very nice 👍
What's the song please someone tell me :)
wow that was pretty cool
1:14
g6........Ng5
Kd7......d2
g7........d1
g8 and white wins because of his move Kd7
It's a draw because of Kd7.
The winning move is Kb6.
