At 3:55 min. you were wrong. Bc5 is the only way to win. All the other squares allows black to play Bd6 and the plan to win the tempo doesn't work. For example: Be3 (instead of Bc5), Bd6 Bg5, Kb6 Bd1, Kc6 Be7, Ba2 and you don't reach the a7-g1 diagonal. The black bishop has to be on g3, f4 or e5.
Its also super important that the white bishop makes the waiting move to c5 and not say d4, because that would allow the black bishop to go to d6, which would then mean the sacrifice doesn't work as the black bishop could retreat to h2 because the king covers c5.
While your point is very valid, it’s not really “super” important. Yes it’s true that you can’t enact your plan after Bd4 Bd6. But if you find yourself making that mistake, you can immediately correct it by playing another bishop waiting move, and black will be forced away from d6. And even if you don’t immediately realize the problem, you haven’t changed the structure and the idea is still possible. No harm no foul
With this puzzle there's a good chance you would have found it eventually. As he stated at the beginning, just determine your strategy and go from there. I came up with the exact same starting moves and knew it was winning position. Besides, this puzzle actually leads you in only one starting direction.
I am great at puzzles, but suck at chess. The problem is when playing chess, I can't be assured that a clever way out of my predicament always exists lol
When you play no one tells you "hey lool there s briliant opportunity there" vs a puzzle, I am not great at either but trying to improove at puzzles...
Doesn’t make much of a difference. Black goes Bd6, and while you can offer the sham sacrifice, you then can’t move on the a7 diagonal because the king is too close and so have to do the same dance anyway.
Well, all that move is achieving is to try to trick black into taking it. If black just moves his bishop instead to g3 or something the move for white is pointless.
1. Ba5 Black King cannot move, it has to move its bishop in the same diagonal. If King Moves, it loses immediately Let us say Black moves Bg3 2. Be1 Now again Black cannot take this sacrifice as it needs to keep the bishop in the diagonal, so it moves its bishop somewhere else on that diagonal (d6/e5/f4/ back to h2) 3. Bf2 Again Black has no moves other than keep moving its bishop on that diagonal 4. Ba7 Now whatever black does, white can 5. Bb8 and win the game
I formulated the only correct plan … however, I didn’t have the patience to carry it out to its logical winning conclusion. Oh, well. Nice puzzle, nonetheless.
There is one more trick. After 3. Bf2 Ka6, and the white Bishop moves to 4. Be3 (instead of c5), then Black plays the tricky move 4 ... Bd6! (and not Bg3 as in the puzzle). You see why? If White moves 5. Bg5? he achives nothing! 5. ... Kb5, 6. Bd8 Kc6 - and now 7. Be7? does not work! Black simply moves the bishop back to h2: 7. ... Bh2 - and white cannot move the Bishop to c5. What now? Therefore, if Black plays 4. ... Bd6!, do not move the white Bishop to g5 "business as usual", but stay on the Diagonal g1-a7, for example move the white Bishop to 5. Bd4!. Now Black moves back to 5. ... Bh2. And now? You cannot gain the tempo via attacking the black bishop. But you can "steal" the magic field d6 from Black: 6. Bc5!. And now, finally, black MUST move the bishop onto a "bad" square, for example 6. ... Bg3. And now you can go on with your plan, attack the black Bishop via 7. Bf2! and win a tempo. And so on. And this is the reason, why you have to play 4. Bc5! instead immediately - it matters! The field d6 is also a magic field for black (same as h2). You have to force the black bishop onto another field than d6/h2.
At 6'34": don't move the King. Move the bishop on his diagonal line. Ist white ba7. Stay on the diagonal. White bb8 move your bishop to the left diagonal from a7 to g1. If white go back a7, go back on the old diagonal to save b8. When white stay on the old diagonal, go to a7 to save b8. What did i miss?
White doesn’t go back to a7. White moves along the b8 diagonal, black has to go a7, then white goes somewhere on the a7 diagonal. Black can either move their bishop to b8 and get taken by the king, take white’s bishop and allow the promotion, or shuffle the king and get their bishop taken by white’s bishop
hmm I fail to see how this is not a draw if Black follows the below strategy. Every time White moves the bishop away from d8, Black moves Kb5. If white moves back to d8 then Black moves Kc6 again. If White moves Bishop to the G1/F2/E3 diagonal Black moves Ka6. If White moves Bishop away form that diagonal Black moves Kb5 again ready to play either Ka6 or Kc6. All other moves by White Black moves the bishop on the diagonal covering b8. I do not see any way White can ever get the Bishop to b8 when Black follows this simple strategy.
Flummer, as described in the video, once the black king gets to a6, the black bishop does not leave that diagonal. By staying within the diagonal, black can't move their king, which means they must move their black bishop. That leaves the black bishop vulnerable to a "sham sacrifice" threat.
And the white strategy is to AVOID black moving the king to b5. White can achieve this by attacking the black bishop when moving away from d8. If the black bishop does not stand on h2, but on g3 (for example), white attacks the black bishop via Bh4. Black has to decide - you to b5 with the King? This costs the bishop! Or hit the white bishop? Then white promotes? Or (finally) move the bishop (back to h2 for example) - but then he did not play Kb5 and cannot avoid the white bishop going to a7. Therefore white makes some good waiting moves to force the black bishop to g3 or another "weak" field. Watch the video!
@@ohlookitisacat7404 Correct. People think just because stockfish is better than humans that it can magically create a solution that doesn't exist for a 100% losing position (assuming correct play from the other side)
At 3:55 min. you were wrong. Bc5 is the only way to win. All the other squares allows black to play Bd6 and the plan to win the tempo doesn't work. For example:
Be3 (instead of Bc5), Bd6
Bg5, Kb6
Bd1, Kc6
Be7, Ba2
and you don't reach the a7-g1 diagonal. The black bishop has to be on g3, f4 or e5.
You mean Bd8 in the 4th line not Bd1.Any way your idea is clear and u are correct.
This is really a great puzzle. Thanks for sharing this with us.😊
I like your channel so much. Really unique i hope you get more subscribers so you continue doing this
Wow! Kings and Pawn start out where they want to be, so it has to be tricky bishop moves to save the day.
Its also super important that the white bishop makes the waiting move to c5 and not say d4, because that would allow the black bishop to go to d6, which would then mean the sacrifice doesn't work as the black bishop could retreat to h2 because the king covers c5.
I think you mean the waiting move should be c5 (not g5).
@@GeekyNeil yes, fixed it
I was thinking that as well.

At 3:45 my idea was to offer the bishop sacrifize but you nrver explored that option
(G1)
I was wondering this as well. Maybe Black sees promotion on the next move and always moves their bishop further up the diagonal to avoid trading.
I managed to figure out most of the puzzle, save for the tempo move. That was amazing!
But the whole point of the study is the tempo move!
With this puzzle there's a good chance you would have found it eventually. As he stated at the beginning, just determine your strategy and go from there.

Really amazing. Certainly I knew this study for a long time, but it is beautiful and instructiv. I will show it other peoples
Good puzzle. I thought I had a different solution but I see the flaw now.
This is the first Bishop ending I studied in the first chessbook I read, "Gli scacchi" by Giuseppe Padulli😊
that type of sacrifice is not a sham, but it is a deflection or a decoy.
Great puzzle
I am great at puzzles, but suck at chess. The problem is when playing chess, I can't be assured that a clever way out of my predicament always exists lol
Me too! The difference between finding a brilliant idea when you're told one is there vs finding it on the fly
When you play no one tells you "hey lool there s briliant opportunity there" vs a puzzle, I am not great at either but trying to improove at puzzles...
I think 1. ba5 also works. The bishop can reach a7 from this side.
It does. It's much faster than the solution he gave in the video.
Also see it, seems like it would save the back and forth dance with the black king, fast forward to the "sham" sacrifice offer.
@@NorthernDruid It definitely does save a lot of time. I put it into Stockfish after I figured it out, and it agrees.
Doesn’t make much of a difference. Black goes Bd6, and while you can offer the sham sacrifice, you then can’t move on the a7 diagonal because the king is too close and so have to do the same dance anyway.
@@chompyzilla You're wrong. I did it in much shorter moves with Ba5. Like I said, Stockfish agrees that Ba5 is the fastest.
I was hoping for Two Promotions to Knights, but it's Beautiful either way.
Very nice. I wanted to give up after 5 or 10 minutes, but I thought it couldn't be that hard with so few pieces, and then I quickly found it.
Good one.
Is there a reason at 3:57 that white cannot move to G1 with their bishop? Black could not afford to take it when it is offered.
Well, all that move is achieving is to try to trick black into taking it. If black just moves his bishop instead to g3 or something the move for white is pointless.
I said this in a comment can't the bishop Chase the bishop
@@donovinbombcookie1785That’s just repetition; all the moves are pointless
Excellent...
Looks like magic!
Black bishop didn't know what got him!
I've used such deflection " sham " sacs a few times, in games, and they are hard to beat.
why would you not move the white bishop to C7?
Why not Bishop to g1?
By 6:16 opponent should resign sees that you know what to do to win !!!
Why can't you move to g1?
I'm going to have to study this one with a chess board in front of me...
very very good puzzle of gm level sir
1. Ba5
Black King cannot move, it has to move its bishop in the same diagonal. If King Moves, it loses immediately
Let us say Black moves Bg3
2. Be1
Now again Black cannot take this sacrifice as it needs to keep the bishop in the diagonal, so it moves its bishop somewhere else on that diagonal (d6/e5/f4/ back to h2)
3. Bf2
Again Black has no moves other than keep moving its bishop on that diagonal
4. Ba7
Now whatever black does, white can 5. Bb8 and win the game
Bishop to g1?
Great !
I formulated the only correct plan … however, I didn’t have the patience to carry it out to its logical winning conclusion.
Oh, well.
Nice puzzle, nonetheless.
Can't you just do Bg1 to sack your bishop and give you a turn with a queen earlier?
No the black bishop would just move along the diagonal to g3.
When the black king went to a6 could you not go to bishop to attack the other bishop because if they take you promote and if they run you chase them

What now?
Therefore, if Black plays 4. ... Bd6!, do not move the white Bishop to g5 "business as usual", but stay on the Diagonal g1-a7, for example move the white Bishop to 5. Bd4!. Now Black moves back to 5. ... Bh2. And now? You cannot gain the tempo via attacking the black bishop. But you can "steal" the magic field d6 from Black: 6. Bc5!. And now, finally, black MUST move the bishop onto a "bad" square, for example 6. ... Bg3. And now you can go on with your plan, attack the black Bishop via 7. Bf2! and win a tempo. And so on.
And this is the reason, why you have to play 4. Bc5! instead immediately - it matters! The field d6 is also a magic field for black (same as h2). You have to force the black bishop onto another field than d6/h2.

That is indeed the right strategy for black but white has a tactic twitch beating this strategy. The answer is in the video!

Have you not watched the video?
not watched the video yet, but i guess you should attack the black bishop from another diagonal.
At 3.40, why not Bg1?
After Bg1 White play b8 Queen!
No, White bishop to g1
@@бообвооб
White Bg1 would be pointless, Black doesnˋt have to take and continues to control b8. And when white goes back black also goes back
Give black to stockfish then show us.
It will give the same result. Black really has no chance to win or stalemate in this puzzle if white plays perfectly.
@@ohlookitisacat7404 Correct. People think just because stockfish is better than humans that it can magically create a solution that doesn't exist for a 100% losing position (assuming correct play from the other side)
Where is L.A. chess prodigy Peter Rhee?
White B must reach b8 and exchange BB..!😂
Bf6 doesn't work because of Kd4
Maybe not the most efficient way but i would just sacrifice bishop on g1 in 3 moves and move on with this game xD
The black bishop would just move along the diagonal to g3 (or f4, or e5, etc.)
Choppy video in 2024 😂
totally has a checkers feel, getting a piece off the edge so you can jump it
Bh4. Kb5. Bf2. Ke6 Bc5. Kb5. Bg1. Bxg1. b8=Q
Solved it under 10 secs.
1.Ba5 Bd6 2.Bb4! Be5 3.Bc3! Bh2 4.Bd4 Kb5 5.Ba7 Ka6 6.Bb8! Bg1 7.Bd6 Ba7 8.Bc5! and black's bishop can no longer guard the queening square. 1-0
After your Bb4, he'd go to Bh2.
You'd never be able to break through without the tempo
Dude you are like 1100, no one would intentionally throw the game like that.
Your video makes me sleep
