I love the channel. In all seriousness, I've seen so many of your puzzles (subscribed) that I was able to call every move of this one. Thanks for posting awesome stuff.
I was so surprised when I had the right idea of h6 and Bh7. Only thing I got wrong was that I thought Bh7 would be immediately after h6, but I didn’t see Kg5 winning the pawn.
If the king had moved to f7 instead of f6 after the pawn moved to h6, then Bh7 would be next (as then black king to g8 would need to be immediately blocked rather than Kg5). Both the king move and the bishop move are needed, but the order is determined by where the black king moves. The pawn move is needed either way, which is why it moves first (otherwise, the black king can move in the way that white isn't set up to blockade in a single move).
What is surprising about this is that the position is not contrived, yet the the solution is one of those counterintuitive ideas. Can definitely see this being useful in a real game some day.
I've been struggling with your puzzles but this one I solved. After pushing the pawn, if black goes to f6 then white goes Kg4 to block black as you showed. If black goes to f7, then white uses the Bishop first to h7.
Pretty interesting puzzle and pretty interesting solution, but I don't like your reasoning for bringing the king up at this specific moment, you could have elaborated that way better. So the whole idea is that it's a race, black king trying to get into h file and white trying to secure that h file by building up a wall. The black king has two ways to get into the h file, either from above or from below, and you have to choose your sequence order such that you prevent that from happening. you play pawn to h6 first because it takes control of the diagonal square g7 which prevents the direct approach of the king to h8. now the king has two ways to go about this, either go for the f6 square attempting to hit the pawn from behind or he goes to f7 attempting to make a run for the corner. each of the two steps puts the king 1 tempo away from making his main plan but 2 tempos away from making his secondary plan. so if the king goes to f7 he can hit g8 in one move and secure the corner but he needs two moves to come back and hit the pawn from behind and vice versa. so if the king goes for f7 you play the bishop to h7 establishing a wall and since it takes two steps for the king to work his other plan, your white king has enough tempo to cover the pawns back establishing a defense with no holes in it. and if the king goes down to f6 then he is 1 tempo away from getting to the pawn then you move your king up to protect it (as it is the more immediate threat) then as it takes the black king two tempos to hit the corner square your bishop is just there in time to make the wall. then your king can make his way to g7 to attend the promotion ceremony.
Thanks. I've never seen that trick with the bishop and pawn blockade before. The flank pawn and wrong bishop is a common endgame theme, so this is good to know.
We were on a cruise in Alaska when the this video was released and exactly 7 days ago there was a presentation of how many Rhode Islands fit into state of Alaska just wow this channel that I watch had it.
My attempt before seeing the solution: I think it's h6, Kf6, Kg4, Kf7, Bh7, Kf6, Kf4, etc. Or if they try to go kf7 immediately then it's: h6, Kf7, Bh7, etc. Same idea, the black king can't enter the g and h files at all and can be pushed out by the white king
Hey Nelson I'm not sure if this is the place to propose this, especially with a video 5 days old already, but I have a challenge for you. Martin's pieces exercise zone of control, meaning if your piece moves near his, your piece can't get away in the same move.
I had the glorious situation recently of managing to salvage an unlikely draw by virtue of being up against a flank pawn and a wrong-colour bishop. So satisfying! Sacrificed my final pawn to sprint my king towards a1. Happy day :-D
The key is the position of the opposing king. If it's close to or in the corner, it's a draw. However, as you see in the featured position, the Black King is far enough away from the corner to give White time to bring up his King and Bishop.
The way you set up the puzzle made the tactic very easy to spot. Admittedly I wanted to go Bh7 first, then h6. I now see that Kf6 spoils any plans in that move order because the g5 and g7 squares are both weak.
Now, if only I can remember to make sure the black king can’t get into the corner ….. Great lesson, Nelson. I enjoyed solving this OTB. It took me many tries, even after you gave white’s first move. I like how you explained the blockade. Visual learner here.
Actually this one is quite easy to solve if you know what's the main threat of black. But yeah, you don't see this result often in a/h pawn, bishop and king vs king endgames. Edit: typo.
Nice puzzle. You can't do anything once the black king gets to the g file, so you have 2 moves to block it. If Kf6, you need to play h6 and move the king up to block the dark squares. If Kf7, you need to play h6 to block the dark square and the only way to block the light squares is Bh7. h6 is required on both lines, so you need to play it first.
When you know there's a win, it's easy to find, but I think most players who know about the wrong rooks pawn endgame would take one look at the position and assume it's a draw.
Nope, it's not possible to checkmate with a king and bishop, even if your opponent helps you (a "helpmate"). The best you can do is stalemate. Because the bishop can't control two adjacent squares, even if you manage to get the opposing king into a corner with your king blocking it so that it only has a single rank or file to move along, your bishop can't both deliver check and control the escape square on the free rank/file. Weirdly, it might be possible to checkmate if your opponent has an extra piece (such as a bishop of his own), since that piece can block the escape square. Practically, though, you won't be able to checkmate your opponent unless they cooperate.
Nelsi 2 years before:
Principle: Flank pawn+ wrong bishop is always a draw
Nelsi now:I already told you " a really good player know right time to violate principles"
What a genius
"almost" always a draw. Far advanced pawn plus close white king and blacks king off on vacation.
Or this position
If it is wrong depends on the king not the pawn.
Crazy that I've actually nearly had this position as black in a game. It's an important position to know lol

Other fun Alaska/Rhode Island facts: Rhode Island has 1062 people per land square mile. Alaska has 1.2 people per land square mile.
I actually found bishop h7 so happy
me too
*not that hard, just to keep the black king away from the promotion square! can easily be done by sliding the bishop over to h7
not very hard though, white need to control the dark square to block the king

Always good things to learn on this channel and he always explains things neatly.😄
Might be the first puzzle I knew the solution to pretty quickly!
Nice endgame study
The critical position is White's pawn on h6, Bishop on h7, and the King on a square that prevents Black from getting to g5.

"King comes up" 💀
My attempt before seeing the solution:
I think it's h6, Kf6, Kg4, Kf7, Bh7, Kf6, Kf4, etc.
Or if they try to go kf7 immediately then it's: h6, Kf7, Bh7, etc.
Same idea, the black king can't enter the g and h files at all and can be pushed out by the white king
nice I got it

Martin's pieces exercise zone of control, meaning if your piece moves near his, your piece can't get away in the same move.
I need to remember this one for practical use! I probably won’t, but I will definitely try 😊
I found h6 and Bh7 with relative ease, box out the Black king and you're golden.
This construction is called the Coral Reef
I had the glorious situation recently of managing to salvage an unlikely draw by virtue of being up against a flank pawn and a wrong-colour bishop. So satisfying!
Sacrificed my final pawn to sprint my king towards a1. Happy day :-D
Great lesson for winning with the setup provided
Finally, one I solved on my own.
Great lesson.. thanks!!

I really don't know this idea. I learn something new from you. Very nice. Keep it up.
I learned something new today. Nice video. Blockade with B and P and have K close by....
This is the first puzzle I was able to solve from the thumbnail pic. Thanks to your previous videos. Thanks for sharing.
Saya suka problem catur seperti ini..👍
Learned, thanks.
The way you set up the puzzle made the tactic very easy to spot. Admittedly I wanted to go Bh7 first, then h6. I now see that Kf6 spoils any plans in that move order because the g5 and g7 squares are both weak.

P6R _(h6)_ and B7R _(Bh7)_ in order to prevent the Black King from reaching the corner.
Took me some time to process how RI and Alaska are relevant to this position 🤔
how is it relevent
Actually this one is quite easy to solve if you know what's the main threat of black. But yeah, you don't see this result often in a/h pawn, bishop and king vs king endgames.
Edit: typo.
You mean a/h file pawns, right?
@@Bartolito201 yeah, typo.
There’s another variation to this :
-Pawn h6
-Bishop f5 (if black king took, the pawn can easily promote)
-Bishop h7
Then push your king and promote
Yep, either order works
I saw immediately that the block that needed to happen. I just visualized it exactly wrong. moving the bishop first.
Can anyone tell me why bg6 at start would not work?
If 1. ...Kf7 then 2.Kg4 is a draw the correct move is Bh7
Nice little nugget. The good thing about ignorance is you don't know what you are not supposed to do, and so you are free to try it anyway!
Nice puzzle. You can't do anything once the black king gets to the g file, so you have 2 moves to block it. If Kf6, you need to play h6 and move the king up to block the dark squares. If Kf7, you need to play h6 to block the dark square and the only way to block the light squares is Bh7. h6 is required on both lines, so you need to play it first.
Build a wall that prevents Black from getting to h8 with h6, Kg4, and Bh7 controlling g5-6-7-8.
I had seen the pawn and bishop blockade when the a and h pawns were called rook pawns.
Rhode Island fits inside of one county in Nebraska (Cherry County).
it makes no difference if you move king first or pawn first as long as third move is bishop h7
Can you start with Bishop G6?
Day before disasters
Can you do h7 first?
I read that (generally speaking) puzzles are legal positions that won't actually come up in a game, but studies can. This would be a study.
3:50 Rather Kf6.
I have been in this position as black before!
What if Kf6 instead?
I don't understand the 1:39 mark, why can't white push his pawn up, it's black's turn, he has to move his king into danger, no?
once the blockade is made, then happily underpromote your pawn to a knight and utilise your B+N mating skills
Short answer is yes, long answer: Always think logically, especially in chess. 😊
I was wrong
I found the right answer and why, but I tried to do it in the wrong order.
Nice puzzles.
i actually know this puzzle when im 7 years old
Haha, i finally solved one before Nelson revealed the solution.
I am beginner and stuck in 1300 elo how to improve i practice daily
king to G4? escort your pawn since g6 is blocked by the bishop
Is this a newly discovered stockfish refutation?
Kf7?
BUILD A WALL
I thought first bishop want to move and pawn and next king
Oh yeah...Definitely that one bishop saves the game.. Pretty smart.!!
what if the king instead of f7 goes f6, wouldnt that be tables too ?
Fun fact: I did not find h6, but I found Bh7.
edit: I also found Kg4
I saw the h6 and Bh7 idea very quickly, but didn’t realize the king could infiltrate on g5 after h6
i love these facts. please keep them going
Like who wants to add Chess 4D and 5D in adventure chess series
Hmmmmm Alaska is Large.
I solved all the puzzle.
I started Bh7. Same idea
You're a strong player and I'm surprised that you found this problem at all difficult.
When you know there's a win, it's easy to find, but I think most players who know about the wrong rooks pawn endgame would take one look at the position and assume it's a draw.
@@kicorse
Yes, perhaps, but I'm assuming that Chess Vibes knew that it was to play and win.
Conceptually this is the same solution, but technically your first move could have been Bh7, instead of the pawn move. Still winning.
I stared at it and my solution was Bh7, then h6, and then move white's king forward. Same 3 moves you did, in a different order.
Doesn't work. After Bh7 Kf6 you can't prevent both Kg7 and Kg5.
Bh7 works too
What’s with the random fact at the beginning?
1 possible difference between NM and IM
IM is fide title and NM is USCF title
Easiest puzzle so far..
umm not trying to be a cocky ass, but that h7 bishop move didn't really dumbfound me
why didnt black play f7 first?
But the king and bishop can checkmate..
Nope, it's not possible to checkmate with a king and bishop, even if your opponent helps you (a "helpmate"). The best you can do is stalemate. Because the bishop can't control two adjacent squares, even if you manage to get the opposing king into a corner with your king blocking it so that it only has a single rank or file to move along, your bishop can't both deliver check and control the escape square on the free rank/file.
Weirdly, it might be possible to checkmate if your opponent has an extra piece (such as a bishop of his own), since that piece can block the escape square. Practically, though, you won't be able to checkmate your opponent unless they cooperate.
Never mind
This is actually a draw
Yay, I got this one lol.
Obviously bishop to h7, pawn to h6, bishop g8, pawn h7. This puzzle is for BABIES.
❤
1:33 how the f its a stalemate, the king can just chose not to move??? 😂😂
Cool!
2:50 and why do you put black king there? You wasted a move. Fake puzzle bro?
Then it's M13 dude
Similar idea of Bh7 works there too
1. h6 Kf7 2. Bh7 Ke7 3. Kf4 Kf6 4. Kg4 Ke5 5. Bg8 Kf6 6. Kh5 Ke5 7. h7 Kd4 8. h8Q+ Kd3 9. Kg4 Kd2 10. Qd4+ Kc2 11. Kf3 Kc1 12. Qc3+ Kb1 13. Qd2 Ka1 14. Qc1#
Wdym? The black king was there previously.
