The position is a known draw IF Black can capture the pawn, OR get his King to any of the four squares of g7, g8, h7, and h8. White's goal is to stop Black from achieving either, and that may require coordination from White's Bishop, pawn, and possibly the King. Only one first move works.
1.Bd7
No other move wins. Any king move is met by Kg1, and the pawn is history.
If 1.Bg2 (or 1.Bf1), Black moves 1...Ke3, followed by f4, e5 (if necessary), and a beeline for h8.
On any of 1.Bg4, Bf5, or Be6, Black will be able to pick up a tempo by attacking the Bishop , aiding the King's path to h8. For example: 1.Be6 Ke3 2.h4 Ke4 (and not Kf4 3. Kd4, and Black is locked out and must move away from the White pawn's queening path) 3.h5 Ke5, and Black reaches h8 safely.
Also, 1.Bc8 doesn't allow White the ability to block out Black's King later, as the Bishop can no longer control the h5 to e8 diagonal.
1....Ke3
Black needs to stay in the "square" of the White pawn's queening path. This move also gains the opposition.
2.h4
Otherwise, Black simply goes to f4, followed by the eventual e5, f6, g7, and h8.
2.... Ke4
The immediate Kf4 is met by Kd4, gaining the opposition and forcing Black out of the pawn's queening path ("square'). Other moves simply allow White pawn to head for h8.
3. h5
Otherwise, Black proceeds to e5, f6, g7, and h8 as above.
3...Ke5
Forced if Black is to stay in the queening path/square.
4. h6
Transposing this with the subsequent Be8 also works.
4....Kf6
Forced in order to stay in the pawn's queening path/square.
5.Be8
Putting Black in Zugzwang. Black must move the King out of range of the pawn and allow it to Queen.
Nice study. I liked following your thinking.
Glad you liked it! 😄
That's a really nice study! Your explanation was a little bit rushed, but clear enough to follow. I thought Bf1 was the solution but your analysis shows that's wrong.
Lovely.
Who composed this known chess study?
I believe this is composed by Alexey Alexejevitsch Troizki (Алексе́й Алексе́евич Тро́ицкий; March 14, 1866 - August 1942). But I am not completely sure. It is hard to know all studies with the name of the composer. Although this famous endgame study I know, when I was 12 years old, now I am 57 years old. The chess composer has the right, if you publish on CZcams, that you add the name of the composer of this study. Even then the study composer is already passed away!
Thanks for the feedback. I couldn't find the composer name from the material I had. I will add the composer name you mentioned in the description.
U stuck yourself on the edge restricting the B,for no reason 😅
In a game you wouldn't be able to calculate all the variations.
Enjoyed that. Maybe never withdraw a piece more than is necessary or less than is necessary. The full withdrawal of the Bishop lessened it's power for no reason.
Glad you enjoyed it :D
Bg2 and win
Bg2 does not work in this position unfortunately. Note Black is not forced to capture with Kxg2.
Sample line: Bg2 Ke3 H4 Kf4 and black catches up with the pawn. This line is similar to the famous Reti Endgame Position
At 14:46 how is it an "elementary" Checkmate? The King can move to any of 3 squares - d7 e7 or f7 and be out of check. Please explain your statement here. Thanks.
Since it is a king vs king and queen ending, I called it an elementary checkmate position. I have not covered the technique to checkmate with a king and queen on the channel but there are definitely loads of content online on this checkmate pattern. I will try to cover the sequence of moves from my next video until checkmate if it helps.
Thanks for watching my video! Appreciate it.
Queen and King vs a lone King is an elementary checkmate. Nothing to do with the position.
@@HD-fy2wu Thank you for your input. I didn't know about that nomenclature. It turns out that, when asked, even ALEXA , through my Echo Dot device, knew this. I learned something new about the game of Chess today.
Bishop g2
After h4 ,5, 6, 7, 8=Queen...
Black King can catch up with e3, f4 to the pawn and that is why Bg2 does not work. The winning move is Bd7.
@@YourAverageChessPlayer yes ,i was wrong
L170 I enjoyed your video.
Thank you very much
Good video, could have been shorter.
Glad you enjoyed the video!
very simple...pls give a harder one...
I will try my best :)
B c8
Bc8 does not work. Bd7 is the only winning move!
Before we start, won't Bf1 win? Black can't threaten the pawn and all we need to do is to go for g8 with our king
Black can play Kf3 with threat of playing Kg4 and then play Ke4 to block our king from progressing. Then black king can take the route of Ke5-f6-g7-h8 uninterrupted and there is nothing white can do about it. The first variation in the video that we look at is indeed Bf1 and you can have a visual explanation there on how this plays out over the board.
after bf1 kf3 be2 comes kg2 and draw
No, Kg2 h4 and white win. Only Ke3, Ke4 or Kf4 is draw move
A good player on blacks side would simply ignore the bishop and chase the pawn no matter what move is played because they understand that's the only way for white to win. In that scenario this game only ends in a stalemate. Am I wrong?
You are wrong. First, know the difference between stalemate and draw. Second, the position is such that black cannot directly pursue the pawn. Black must try to use Reti's idea about the unique geometry of the chessboard. White, however, has the bishop to frustrate that plan.
@@francisminiter2692 "Black cannot directly pursue the pawn" yes it can, what do you even base that off of? ???????????
@@gavin2870 because the pawn and the bishop can prevent the black king from accessing the needed squares. Did you watch the video?
