Position #2 is mindblowing. Literally every underpromotion works under a specific circumstance, and the queen is bad everytime. That's a truly incredible position to me, much more than the others.
What is crazy to me is that in position #2, after Bh7+ and Kg7, h6+ does not quite work. The reason is because of Kf6! where black ignores both the free pawn and bishop in order to threaten the e pawn as well as take the rook with the queen.
Congratulations, soldier! You've exceeded all expectations. You've achieved the impossible. You defended friendly units. You defeated enemy units. You singlehandedly destroyed an enemy fortification. You're one of the last survivors of your unit. You ran the gauntlet of hell under enemy fire and still prevailed against all odds. We'd normally promote you to an officer rank. But we need a Corporal to win this battle. So you're a Corporal.
Normally a queen is strictly better than a rook or bishop (I thought only knight could work in some rare cases) but with the special rules of stalemate, we are presented this extreme case that it is not. Btw: In Asia we play Chinese chess where a stalemate would not be a draw but causing the player to move losing the game, so it is even more astonishing to me
@@johnathanpatrick6118 Not exactly. The pieces and board of the Chinese Chess is very different. The "knight" cannot move to the two places in the direction where the immediate adjacent square is occupied, for example.
Those puzzles were completely mind-boggling. Especially the second one, where there are 3 underpromotions in the different variations. What this teaches us is to never give up. Even if a position looks completely hopeless there may be some kind of crazy winning move available on the board. Thank you so much for the amazing video!
18:09 if anyone was wondering about the Qxf6 sub-line there it is: 2. ... Qxf6 3. exf6 Ke5 4. fxg7 ... 5. g8=Q 3. ... gxf6 4. f4 ... 5. c3# Edit: corrected the typo.
@@dirkrommeswinkel1765 I'm really wondering if people can read the comment first before replying. I mean, my original comment literally starts with the answer to your question. Do you understand what 2. ... Qxf6 means? It means that black's queen captured something on the f6 square on the second move, in this case the knight was captured. This sub-line wasn't presented in the video and that's why I wrote my comment. If queen captures the knight then exf6 and white have two threats. The first threat is promotion to a new queen in the next 2 moves and the second one is mate in two if black responses to the first threat and recaptures gxf6 (this sub-sub-line is also mentioned in my original comment) or if black makes any other move except Ke5. So the best black can do is to move the king out of the mating net so Ke5 but then white's pawn promotes in two moves. If you cannot visualise it then set the position on the board and move the pieces according to the line by yourself.
12:20 the human move here is Ng3+ followed by Ng4. It doesn't force mate quite as quickly, but your two knights and bishop and two pawns will win easily, without having to calculate the weird ending in the actual puzzle.
@@cephalosjr.1835 it's a tricky mate in 7 vs a dead easy mate in 21 (per stockfish). In a real game, opponent would resign after you capture his pawn and still have BNNPP yourself.
6:53 I did Pawn H6 check. slower but I like it more because this puzzle was trying to force me to never promote to queen. Some black king moves lose to queen promotion this way without stalemate because the pawn is no longer blocking the Kg6 escape route.
15:47 No.4 Nice deflection by queen sac. I don't recall seeing that sort of deflection before. The sacrificing side forced the deflected piece not to block the king, or to unguard a square, or to unpin something, but to cross a critical square, ending up on the wrong side of it.

Rb8+ K moves; 7. a8(Q) Rxa8) it's winnable for White, but gotta watch out for knight forks. Any one of them happens and the position is drawn because a king and knight can't checkmate the opposing king.
Hello, please make video about my composition. Here is the starting position: White: Kh3, Ne5, b5, d4, e6, c7, a7 Black: Kh8, Ne7, Bh1, Rc1. White to play and win
Position 4 gets really interesting if you decide to sac the queen for the knight. Getting the win for white gets tricky. as black has a lot of ways to spoil it. I originally analysed it missing a critical white pawn and was wondering if the study was flawed. Nope, just my eyesight :)
I have a question why in position 4 can't the queen capture the knight on f6?!?! D3 does not offer checkmate because the E5 pawn is not defended. If white plays f4 the Queen is free to capture f4?!? Please help what am I missing?! Figured it out exg6 if fxg6 F4 mate on D3 is unavoidable Forcing K e5 fxg7 and queens
The knight one reminds me of the coolest thing I ever did in chess. I was playing against my computer and there was a big pawn structure from both sides. I managed to maneuver my knight and fork most of the computer’s pieces (by checking with my knight) before finally delivering checkmate. Every move I made was check
On the Internet Chess Club I onced checked an opponent 62 times!!!......in a row!!!!! He finally repeated the position 3 times and I claimed a draw. I told him my 62 consecutive checks was a personal record. I think that only pi$$ed him off further.
I think you can claim a draw if you do 50 moves without capturing a piece. Or you can just say "My name's Anish Giri" and claim a draw before the game even starts.
4:15 Position 2 - Can someone explain why not rook to g1? That would put the king in check and give him three possible moves. The first one is to block with the queen, moving her to g4, but that wouldn't change anything because the rook could just take her putting black's king again in check. The second possible move is to block with the bishop, but then the rook takes the bishop and is also guarded by the pawn and the white bishop, so the king moves to h7 or h8. Then white promotes with the pawn also killing black's rook. If the king didn't move to h7 yet, he does it now. If he already is here, black can check white with bishop to a2, but then the king just takes. Anyways, black's king is currently on h7, so white moves the rook somewhere else, making a discovery check using the bishop. And that's actually mate because of white's queen. The third move is just to move the king to h8 (he can't move to h7 because of the bishop), but then it's mate in one as white promotes his pawn to a queen. To summary, the second possible move for black is mate in 4 or 5 moves (depending whether the king firstly moves to h8 or h7) and the third one is mate in two. The first one can just gain time for black, but will result in position 2 or 3 anyways. The answer in that Chess Vibes shows is fantastic, but isn't it simpler to just check with the rook?
(@20:33) - After 1 … Ra3, 2 Rb8+! K-moves, 3 a8=Q and black has to sack the rook for the newly promoted queen, or try to dance around with white’s king by giving check, while not getting captured by white’s rook or queen, which won’t work as the new queen guards the a-file, and the only other checking move with the rook is 3 … Rh3+??, 4 Kxh3. Black could try 3 … Nf5+, 4 Kg4 Nh6+, 5 Kf4 and - again - black has no useful checks here. (Or 3 … Nf5+, 4 Kg4 Ne3+, 5 Kh5! And black sucks on a dry well, as the knight now blocks the 3rd rank, and has no useful checks!)
For position 1 wouldn't moving the king off the rim be the best first move? It lets you take any promotion with the bishop, and if black takes with rook, you aren't in check to promote
That was my solution. If they continue to check with rook you just move king down until there are no more options (as long as you don't block your bishop line). Eventually they promote and you trade with bishop and then white promotes and you have a pawn and queen to a rook
2:11 Could you play pawn to a7 here? If black promotes, then after queen takes rook takes then white can promote and fork the king and rook. I couldn't see any other positions winning either.
@@crazyduckthing1210 after a7, black plays h1Q+ (check) white plays Qxh1 and now black plays Rxh1+ (check again). Because of the check, white is forced to waste time to move his king (eg. He can play Kg6) and then black plays Rh8, stopping the pawn with a winning position.
For the second one, actually, I'll think the underpromotion to the knight is quite easy to win, even if the black bishop takes the pawn. We just need to trade the knight for that bishop, then king+rook will be quite easy by using the rook to limit the black king's movement, and then using the king and rook to slowly push the king to one of the sides and be sure to let the kings be in a knight's movement position to force the black to run away from the white king. Once it moves back, we can checkmate with the rook
Thanks they were amazing. In Position #4 time 17:17 when Knight blocked the queen the queen can capture the knight and f4 can not be played because queen can capture it and give check. The other pawn also can not give check because king can capture the pawn d5.
18:38 the answer to puzzle number 4 is actually the beginning of a new Chess puzzle. White to play and win. Here the knight looks trapped, and black has more pawns on the Kingside. But the answer to this puzzle will blow your mind.
#2 the fork was actually kinda obvious, but I think if you promote to queen it still might work because you are up 3 points and black is kinda cramped in one side of the board
Position 1, if I had to guess, bishop to h1, blocking the pawn promotion. Rook takes but that also blocks his pawn and then white promotes to queen Edit, saw the second part of it, again, I assume white blocks the pawn with queen to h1 sacrificing the queen for the same combination, but this time when whites pawn promotes on a8, it also puts the king in check
@@sc2cooptutorials679 they know that, they're just saying that looking at it they thought that that would work but then as he explained it in the video and understood that that isn't how that would go and how these positions are really cool
Question at 08:36 -- Is anything wrong with the following: Bh7+ Kg7 h6+ and if Kxh7 => Pxf8 promoting to a knight, else: Kx6 Pxf8 promoting to a queen and after the king moves out of the way / takes the bishop Rxd7
I think some important variations have to be covered in the end of Puzzle number 4. If after Nf6 black plays either Qa8 or Qh8 then f4 does not work because black will give a check with the queen in g2 in the first case and in h2 in the second case. For this reason after Qa8 white should play Ng4 to protect the e5 pawn and the threat c3 to checkmate black's king is unstoppable. If black plays Qh8 (where he also threatens Qh6+ ruining whites position), then white has to play again Ng4 threatening again c3 with checkmate. The only way to avoid this checkmate for black is to play Qh6+ and white has to play Nxh6. If black captures the knings gxh6 then f4 and the threat c3 is unstippable. Thus the only way for black to continue the game is to play Kxe5 and then white has to save the knight by either playing Ng4 or Ng8 or Kf7 (I am not sure if all three are winning, but white has to be cautious because black has a passed pawn in the a row and some precision is required/ In a game I would play Ng4+ followed by Ne3 and then white may protect the f pawn with the king and play c3 and Nc2 having an easy win).
That's a draw. After Kf6 and Rxd7, Black control the promotion square, win the bishop, and basically has defensive resources necessary to not get checkmated.
this is insane. A Puzzle that not only requires an underpromition, but all three underpromition in the three possible variations and there isn't even a variation when you want to promote to a queen. just wow
position #2 : after Kg8 to g7, why not Rg1 ? What will black do ? taking the bishop or Kh8 ? Depending on the king's move, promote the pawn by taking the rook
I was thinking the same. If Rg1+, Kh8, exf8, followed by either Qxg8 or Qg7 for white If Rg1+, Bg6, then Bc4+
Год назад
Why at 29:49 black just does not play rook to e8? And continues blocking getting the queen with rook and knight? Than it seems advantage is still with black. It has more pieces
i love it man u got that pedagogy that i can see trough the moove b4 you explain them like i dont know if im genius or your just a good profesor, plus 1 sub !
19:55 After Kh2 and another check, the check with the pawn is not possible. Also, I don't understand what purpose it serves, the black can castle right away.
After white plays Kh2, black can just play Ra3 and sacrifice the rook for the pawn. As for the pawn move, it makes it trickier for white to win, as they get to find 4. Kg4, then 6. Kh5, and finally 7. Kg5, while if you don't play 2... h4, white can just hide their king on h3 or h2 after Nf5+, and it's easy
[edit: Okay #4 I watched the solution, gg] selfnote: 16:44 (2nd pause of puzzle 4) Honestly you gotta give a tip after pause, I tried now around a lot without hints or evaluation line and can't do it. For instance moving the knight to g5 to threaten check and moving your pawn doesn't seem to make sense because of the perpetual check and even mate if I check (king just runs towards me), I also tried pc3+ different check variations which simply ends up in losing all the central pawns, doing stupid stuff such as the king simply loses the past pawn, other variations: A fork on e6 couldn't be accomplished because of tempo of black, or "offering" the night on d6 as stupid as it looks (black could just ignore it, go for check or improve the positon elsewhere), won't work because black is up a turn in all cases. So 1. Ne4 wouldn't work for me personally I have no follow up plan, while as with 1.pc3+ 2.Nd7+ i would at least have gotten a queen and a decent position. So I really feel offering a hint after the pause instead of solving the turn right away would be quite sweet.
7:11 can white goes bishop g6? If the black bishop takes the white bishop then the white pawn will take the black bishop, If the black king takes the white pawn then the another white pawn will takes the rook and promote to a knight and check and capture the black queen
I love these videos, I feel I've learned more about chess in half a year than all my life. I have a question about position #2: why wouldnt white play Rg1+ as the first move? Black King has one square to go and then pawn promotion to queen with check and the rest is history?
2:20 Why can't Queen just go to f3? I mean Black is forced to move the rook so you can move your pawn (if black doesn't play Rook d7) or your queen to h1 if Black moves Rook d7. Edit: Forgot to mention Queen f3 also blocks Rook from checking the King
12:21 why not just knight back to g3+ check and cover promotion square. That’s what I would probably have done in game and tired to bring my king and pawns closer to promotion. It might be some black knight moves that draw this I guess but it’s hard to see
I thought I saw an opportunity for an alternate play for position #2 before realizing there was an easy escape from it. I had thought that you could simply move the rook to g1, forcing the king into check. This leaves only three possible plays: blocking with the queen, blocking with the bishop, or fleeing to h8. Unfortunately if they blocked with the bishop, this leaves nothing the rook can do to force the king into checkmate because if you took the bishop, the only viable option to pressure the opponent and prevent them from setting up moves on you, the king could simply move to f7 and escape your grasp, ruining any chance for victory you may have had.
Sorry but isn't there a direct checkmate im position #2, on Rg1? After Rg1, it's a check. So the King is either forced to move to h8, or block it with the Queen or Bishop, which is useless and would lead back to h8. Then p×Rf8 and promotes to a Queen/Rook. Blocking with Bishop, again useless as R×Bg8 it would lead to a checkmate...
Saccing the queen leads to 2. ... Qxf6 3.exf6 Which then leads to: 3. ... gxf6 4. f4 and Black cannot stop 5.c3# Alternatively: 3. ... Ke5 4.fxg7 leads to an unstoppable promotion
Position 4#: if the Queen capture the horse after the horse block(f6) there is no check mate from white. And i think, even if white capture the black queen, black wins because the pawn in A line.
@@MarkYeung1 same for taking the other bishop. no matter which bishop you take, the next play by white is the same. i'm just trying to figure out why the King couldn't have taken the new black square bishop White has on f8 as an option?
@@MusicHunter111000 Yes true... I realized that after posting this comment 2 months back... I hope your answers helps others too... 😊 Thanks for explaining ...👍🏻
There is a mistake in explanation of position #4, time 17:45, black queen should take white knight Qf8 6 and if queen is not taken by white pawn, then white is losing, but if it is taken Pe5 f6, than black pawn takes white one Pg7 f6 and in any case black is staying with one pawn more, better position and it is straight win for black. White can only win if (from original starting position time 15.46): Pc3 c4 cheek to black king, black king must take Kd4 e5, white knight jump Nf6 d7 it is cheek to black King and save position on f8, so black king must move (best is on d6) and white pawn is out for white queen Pf7 f8, keeping white pawn on f2 safe. White probably wins later but it should be analyzed. Regards Igor
on position #2 cant you first check the king at g1 with the rook (it cant be blocked by the bishop or the queen( the only square is H8 then you can take the rook with check by promoting to a rook or a queen with the only move to block with the bishop and mate next move?
ok you can block with the bishop as it frees up the f7 square for the king and then no matter what you do you are losing the pawn (either for the rook or for the queen and hence will be a draw at best)
That line of play would lead to 1. Rg1+ Bg6 2. Rxg6+ Kf7 And now you've lost your pawn and the king is no longer trapped. Possibly still winnable but black still has a queen and can threaten to draw by perpetual check.
What surprises me the most is that, after the 5th position, I used the tablebase and saw that it doesn't work as long as castling is a available... It's quite exceptional that castling is still available when 7 pieces or less are on the board, but still...
I was really confused by that position, because it looked like an easy win for white. I thought "Just push the pawn up twice for mate. It's unstoppable. Black can do a pointless check with the rook to delay it for a move, but that's about it" and then Nelson revealed Black's follow up was castling, which I hadn't even considered, because no real game would ever reach such a weird situation where castling is still available.
@@AutPen38 It could still happen in real game if both side agrees to reach this particular position, but yeah. The chance of it occuring in real game is slim.

The second possible move is to block with the bishop, but then the rook takes the bishop and is also guarded by the pawn and the white bishop, so the king moves to h7 or h8. Then white promotes with the pawn also killing black's rook. If the king didn't move to h7 yet, he does it now. If he already is here, black can check white with bishop to a2, but then the king just takes. Anyways, black's king is currently on h7, so white moves the rook somewhere else, making a discovery check using the bishop. And that's actually mate because of white's queen.
The third move is just to move the king to h8 (he can't move to h7 because of the bishop), but then it's mate in one as white promotes his pawn to a queen.
To summary, the second possible move for black is mate in 4 or 5 moves (depending whether the king firstly moves to h8 or h7) and the third one is mate in two. The first one can just gain time for black, but will result in position 2 or 3 anyways. The answer in that Chess Vibes shows is fantastic, but isn't it simpler to just check with the rook?
1. Rg1+? ...Bg6!
2. Rxg6+ ...Kf7
Thanks!
I love this video so much I can’t stop watching it 😊😊😊😊😊
one of the best positions and chess video i ever saw
(@20:33) - After 1 … Ra3, 2 Rb8+! K-moves, 3 a8=Q and black has to sack the rook for the newly promoted queen, or try to dance around with white’s king by giving check, while not getting captured by white’s rook or queen, which won’t work as the new queen guards the a-file, and the only other checking move with the rook is 3 … Rh3+??, 4 Kxh3. Black could try 3 … Nf5+, 4 Kg4 Nh6+, 5 Kf4 and - again - black has no useful checks here. (Or 3 … Nf5+, 4 Kg4 Ne3+, 5 Kh5! And black sucks on a dry well, as the knight now blocks the 3rd rank, and has no useful checks!)
4th puzzle is wrong
after Nf6, Qh8 and you cant stop the queen from giving a check the next move and winning the pawn with a fork
21:25 - It’s a double check - Nf5 and Rh8 are both checks.
Your channel is unique while comparing to other's. Keep up the good work. Hope I can improve the rating because of u.
For position 1 wouldn't moving the king off the rim be the best first move? It lets you take any promotion with the bishop, and if black takes with rook, you aren't in check to promote
That was my solution. If they continue to check with rook you just move king down until there are no more options (as long as you don't block your bishop line). Eventually they promote and you trade with bishop and then white promotes and you have a pawn and queen to a rook
2:11 Could you play pawn to a7 here? If black promotes, then after queen takes rook takes then white can promote and fork the king and rook. I couldn't see any other positions winning either.
Black Rook takes Queen AND chech. Do you see?
@@maingotrong3790 Not really, can you use chess notation after 1.a7 to make it more clear what you're saying?
@@crazyduckthing1210 after a7, black plays h1Q+ (check) white plays Qxh1 and now black plays Rxh1+ (check again). Because of the check, white is forced to waste time to move his king (eg. He can play Kg6) and then black plays Rh8, stopping the pawn with a winning position.
@@jovindsouza3407 Thanks, somehow missed the rook check. Makes sense
For the second one, actually, I'll think the underpromotion to the knight is quite easy to win, even if the black bishop takes the pawn. We just need to trade the knight for that bishop, then king+rook will be quite easy by using the rook to limit the black king's movement, and then using the king and rook to slowly push the king to one of the sides and be sure to let the kings be in a knight's movement position to force the black to run away from the white king. Once it moves back, we can checkmate with the rook
of course it is
For position two, I jokingly said exf8=B because it would be funny to promote to bishop. I didn't think that would be the actual solution!
on problem #4 you coulda just moved the pawn up and won when the knight was beside the king instead of making a queen at 16:50
The king could have taken at c4 or e5
yeah i see e5 now you right i retract my statement
@@7pheonix omg I’m so stupid I made a mistake correcting someone else when I was looking at the board!! 🤦🏻♂️
17:10 isn’t pawn to c3 checkmate?
Yes im so confused
Kxe5
13:00 And the knight draws the outline of a king around the enemy king! Talk about humiliation!
Opening position #4 on May 28th 2022 position was winnable from the first move as the Black King had no place to go at the beginning.
The king can capture the pawn on E5!
Thanks they were amazing. In Position #4 time 17:17 when Knight blocked the queen the queen can capture the knight and f4 can not be played because queen can capture it and give check. The other pawn also can not give check because king can capture the pawn d5.
Bruh if queen takes knight then the pawn takes the Queen and it is a better position for white now
Then c3#
...Qxf6 / exf6 gxf6 / f4 moves / c3 checkmate. But should have been explained.
Qxf6 is pretty freaking obvious. Shouldn't need to explain why this leads to the same line hes explained 4 times already
I guess nelson didnt expect 50% of this community to be brainlets
King and Rook v King and Knight can be, according to Howard Staunton, a win for the King and Rook. Mind you,, it is a difficult checkmate.
At 7:20 after sacrificing the bishop you can iive a check with the queen, you can sacrifice her and then get the queen.
18:38 the answer to puzzle number 4 is actually the beginning of a new Chess puzzle. White to play and win. Here the knight looks trapped, and black has more pawns on the Kingside. But the answer to this puzzle will blow your mind.
Stuff like this is why I love chess. Such a strategic and in depth game.
#2 the fork was actually kinda obvious, but I think if you promote to queen it still might work because you are up 3 points and black is kinda cramped in one side of the board
4:28 why is Rg2+ not wining ? After Kh8, pawn takes rook
I agree
nope .
After the check,the bishop wiill block to give black f7.
Position 1, if I had to guess, bishop to h1, blocking the pawn promotion. Rook takes but that also blocks his pawn and then white promotes to queen
Edit, saw the second part of it, again, I assume white blocks the pawn with queen to h1 sacrificing the queen for the same combination, but this time when whites pawn promotes on a8, it also puts the king in check
In position 4 it doesn't seem like you need to block the queen off just go for c3 check right away. These are the best positions ever
Then the king will capture the pawn on e5 and it's game over for white.
@@sc2cooptutorials679 they know that, they're just saying that looking at it they thought that that would work but then as he explained it in the video and understood that that isn't how that would go and how these positions are really cool
Question at 08:36 -- Is anything wrong with the following:
Bh7+ Kg7
h6+
and if Kxh7 => Pxf8 promoting to a knight,
else:
Kx6 Pxf8 promoting to a queen and after the king moves out of the way / takes the bishop
Rxd7
I've never really seen situations where the promotion wasn't a queen or knight and started from the same position.
At the pos 2 what about instead of promoting to a bishop u move the rock for king check?
I think some important variations have to be covered in the end of Puzzle number 4. If after Nf6 black plays either Qa8 or Qh8 then f4 does not work because black will give a check with the queen in g2 in the first case and in h2 in the second case. For this reason after Qa8 white should play Ng4 to protect the e5 pawn and the threat c3 to checkmate black's king is unstoppable. If black plays Qh8 (where he also threatens Qh6+ ruining whites position), then white has to play again Ng4 threatening again c3 with checkmate. The only way to avoid this checkmate for black is to play Qh6+ and white has to play Nxh6. If black captures the knings gxh6 then f4 and the threat c3 is unstippable. Thus the only way for black to continue the game is to play Kxe5 and then white has to save the knight by either playing Ng4 or Ng8 or Kf7 (I am not sure if all three are winning, but white has to be cautious because black has a passed pawn in the a row and some precision is required/ In a game I would play Ng4+ followed by Ne3 and then white may protect the f pawn with the king and play c3 and Nc2 having an easy win).
In puzzle2, instead of underpromo to bishop, playing pawn to h6 check forces the capture of either the pawn or bishop on h6 or h7
Position #4 is instant win to white (pawn C2 go to C3) !
15:48
Unmentioned trick in position number two 6:05 : u can move ur pawn to h6 and no matter what king does u promote queen or night on the next move
That's a draw. After Kf6 and Rxd7, Black control the promotion square, win the bishop, and basically has defensive resources necessary to not get checkmated.
Nelson what about at 20:32 give a check with rook and then promote to queen
Black takes the queen with the rook, and then rook vs knight is a draw (in this case)
For position 3, can’t you do knight on d6 to b5? Then you can move bishop or the knight depending on the square black king moves on?
17:49 The Black may take the Knight by the Queen, the pawn takes the Queen, the Black pawn takes the white pawn, and this position is WONE for Black!
nope, following all the moves you said. its mate in 2 for white.
pawn to f4 then
black cant do anything to stop
pawn to c3 mate.
Exciting to see someone get excited about these cool plays
this is insane. A Puzzle that not only requires an underpromition, but all three underpromition in the three possible variations and there isn't even a variation when you want to promote to a queen. just wow
Fing crazy Teacher Nelson awesome stuff...I Love it!👍🤯
position #2 : after Kg8 to g7, why not Rg1 ? What will black do ? taking the bishop or Kh8 ? Depending on the king's move, promote the pawn by taking the rook
I was thinking the same.
If Rg1+, Kh8, exf8, followed by either Qxg8 or Qg7 for white
If Rg1+, Bg6, then Bc4+
Why at 29:49 black just does not play rook to e8? And continues blocking getting the queen with rook and knight? Than it seems advantage is still with black. It has more pieces
i love it man u got that pedagogy that i can see trough the moove b4 you explain them like i dont know if im genius or your just a good profesor, plus 1 sub !
At 18:55 (the end of position 4) worth mentioning is: Black had Qh8 so white had to find the move Ng4 to protect h6 and e5
What if in this position queen takes the knight
@@rahuldhar7526 Qxf6, exf, gxf, f4, a5/e5 or c6, c3#
19:55 After Kh2 and another check, the check with the pawn is not possible. Also, I don't understand what purpose it serves, the black can castle right away.
If black castle after Kxg3, black's rook is stuck defending eight-rank. There's is no Rg2 check. A move like Rc6 attack the knight and threatened Ra6.
After white plays Kh2, black can just play Ra3 and sacrifice the rook for the pawn.
As for the pawn move, it makes it trickier for white to win, as they get to find 4. Kg4, then 6. Kh5, and finally 7. Kg5, while if you don't play 2... h4, white can just hide their king on h3 or h2 after Nf5+, and it's easy
Position 4 18:20 what if you play Qh8 and not Qb8 ? how do you stop checks i dont see it ...
I'm so proud that when I paused on 2 I found the bishop underpromotion
Position 2 is one of the best puzzles I've ever seen
Great vids, as my end game play is still terrible and I never see these subtle plays.
[edit: Okay #4 I watched the solution, gg] selfnote: 16:44 (2nd pause of puzzle 4) Honestly you gotta give a tip after pause, I tried now around a lot without hints or evaluation line and can't do it. For instance moving the knight to g5 to threaten check and moving your pawn doesn't seem to make sense because of the perpetual check and even mate if I check (king just runs towards me), I also tried pc3+ different check variations which simply ends up in losing all the central pawns, doing stupid stuff such as the king simply loses the past pawn, other variations: A fork on e6 couldn't be accomplished because of tempo of black, or "offering" the night on d6 as stupid as it looks (black could just ignore it, go for check or improve the positon elsewhere), won't work because black is up a turn in all cases. So 1. Ne4 wouldn't work for me personally I have no follow up plan, while as with 1.pc3+ 2.Nd7+ i would at least have gotten a queen and a decent position. So I really feel offering a hint after the pause instead of solving the turn right away would be quite sweet.
Selfnote: 18:20 second pause - "What's the move we play here?" edit: nice; I got that one 🙂
Or pawn to C3 for instant checkmate
There's Kxe5@@Kambyday
7:11 can white goes bishop g6? If the black bishop takes the white bishop then the white pawn will take the black bishop, If the black king takes the white pawn then the another white pawn will takes the rook and promote to a knight and check and capture the black queen
If
Position 4: c3+ force moves Kxe5, then Nd7+ gives 4 options for the king, all of which are in check once f8 promotes
In position 2 when king moves to g7, push pawn to h6, if the king captures the pawn , u can promote to a queen and win
In position #4 black could have taken the knight with the queen which would lead to 4 pawns vs 4 pawns.
I love these videos, I feel I've learned more about chess in half a year than all my life.
I have a question about position #2: why wouldnt white play Rg1+ as the first move? Black King has one square to go and then pawn promotion to queen with check and the rest is history?
Black would play Bg6 which actually leads to a draw! Good question though
@@ChessVibesOfficial oh yeah thats True. I didnt see that one. Thanks alot for the reply and keep making these fantastic videos bro. 💪😎
Can you show the draw? After Bg6 then white moves Bc4? King moves h7. Pawn takes rook to become queen.
17:17 position #4, after Nf6 simply QxNf6 and black is winning.
Position #2. Rg1, forcing the black king to go corner then, promote a queen and mate.
in position 4 there is mate in one if you move to c3
4 : 13 Rg1 check and kh8 , ef8 mate
2:20 Why can't Queen just go to f3? I mean Black is forced to move the rook so you can move your pawn (if black doesn't play Rook d7) or your queen to h1 if Black moves Rook d7.
Edit: Forgot to mention Queen f3 also blocks Rook from checking the King
Black isn't forced to move the rook, and can just promote the pawn, putting you in check and linking queen and rook.
amazing puzzles as always👍👌
12:21 why not just knight back to g3+ check and cover promotion square. That’s what I would probably have done in game and tired to bring my king and pawns closer to promotion. It might be some black knight moves that draw this I guess but it’s hard to see
4:23 isn't rook g1 better since king forced to h8 then pawn takes rook checkmate?
Bishop blocks
At 6:30 ... After Queening throw in Qg7 forcing KxQ, then RxQ
Position 2 is one mindblowing stalemate problem
I thought I saw an opportunity for an alternate play for position #2 before realizing there was an easy escape from it. I had thought that you could simply move the rook to g1, forcing the king into check. This leaves only three possible plays: blocking with the queen, blocking with the bishop, or fleeing to h8. Unfortunately if they blocked with the bishop, this leaves nothing the rook can do to force the king into checkmate because if you took the bishop, the only viable option to pressure the opponent and prevent them from setting up moves on you, the king could simply move to f7 and escape your grasp, ruining any chance for victory you may have had.
Sorry but isn't there a direct checkmate im position #2, on Rg1?
After Rg1, it's a check. So the King is either forced to move to h8, or block it with the Queen or Bishop, which is useless and would lead back to h8.
Then p×Rf8 and promotes to a Queen/Rook. Blocking with Bishop, again useless as R×Bg8 it would lead to a checkmate...
After rg1 bg6 an escape route is created on f7, where the bishop was.
In the 4th puzzle after you play Nf6, cant you sac the queen for the knight?
Saccing the queen leads to
2. ... Qxf6 3.exf6
Which then leads to:
3. ... gxf6 4. f4 and Black cannot stop 5.c3#
Alternatively:
3. ... Ke5 4.fxg7 leads to an unstoppable promotion
@@selectivepontification8766 thanks
Position#2... That's a thunder promotion🤯🤯
I’ve legitimately been mind blown just in the morning and I feel really fresh now! Tysm
Position 4#: if the Queen capture the horse after the horse block(f6) there is no check mate from white. And i think, even if white capture the black queen, black wins because the pawn in A line.
on position 2, when you promote to a bishop, what's stopping black from taking the new bishop over the old one?
It will be followed by RxQ at d7.
@@MarkYeung1 same for taking the other bishop. no matter which bishop you take, the next play by white is the same. i'm just trying to figure out why the King couldn't have taken the new black square bishop White has on f8 as an option?
18:50 what if the queen captures the knight at this moment... its hard to win against that 5 pawn structure...
Thought this, but same pawn checkmate as black would have to take white pawn to prevent new queen, leaving time to push pawn to f4 then pawn to c3
@@MusicHunter111000 Yes true... I realized that after posting this comment 2 months back... I hope your answers helps others too... 😊 Thanks for explaining ...👍🏻
There is a mistake in explanation of position #4, time 17:45, black queen should take white knight Qf8 6 and if queen is not taken by white pawn, then white is losing, but if it is taken Pe5 f6, than black pawn takes white one Pg7 f6 and in any case black is staying with one pawn more, better position and it is straight win for black.
White can only win if (from original starting position time 15.46):
Pc3 c4 cheek to black king, black king must take Kd4 e5, white knight jump Nf6 d7 it is cheek to black King and save position on f8, so black king must move (best is on d6) and white pawn is out for white queen Pf7 f8, keeping white pawn on f2 safe.
White probably wins later but it should be analyzed.
Regards Igor
on position #2 cant you first check the king at g1 with the rook (it cant be blocked by the bishop or the queen( the only square is H8 then you can take the rook with check by promoting to a rook or a queen with the only move to block with the bishop and mate next move?
ok you can block with the bishop as it frees up the f7 square for the king and then no matter what you do you are losing the pawn (either for the rook or for the queen and hence will be a draw at best)
That line of play would lead to
1. Rg1+ Bg6 2. Rxg6+ Kf7
And now you've lost your pawn and the king is no longer trapped.
Possibly still winnable but black still has a queen and can threaten to draw by perpetual check.
@@selectivepontification8766 Black could even get mating threats.
20:31 what if you check with rook, take queen , he,ll take the queen maybe then you,ll take his rook with your rook ?
What surprises me the most is that, after the 5th position, I used the tablebase and saw that it doesn't work as long as castling is a available...
It's quite exceptional that castling is still available when 7 pieces or less are on the board, but still...
I was really confused by that position, because it looked like an easy win for white. I thought "Just push the pawn up twice for mate. It's unstoppable. Black can do a pointless check with the rook to delay it for a move, but that's about it" and then Nelson revealed Black's follow up was castling, which I hadn't even considered, because no real game would ever reach such a weird situation where castling is still available.
@@AutPen38 It could still happen in real game if both side agrees to reach this particular position, but yeah. The chance of it occuring in real game is slim.
