Why not White Bishop to f2 traps the king then it's either just Knight to e3 Mate or if Black covers with their Bishop you have to dance around knight to f5 giving you options for e3 / g3 and Black can't cover both
@@user-ch2kt8mz4b good excuse for not being prepared for class the next day. Once I got a bug in my eye...still there, but no longer an excuse.
Please continue the Chess adventures series

Yes
There's a separate channel for that
Give him time man he's been in the hospital, my boy Nelson needs to be okay before anything else
@@BL-vs4cdso true
Many persons asked, what if after Bb6 black plays Bd2 (instead of Be1, shown in the video).
Then Bf2 Bf4 Nc3 Bd2 Ne4 Bf4 (only square, where the bishop stops both, Nd2# and Ng3#, but now the f2 bishop is defended by the knight, so) Kxf4 wins the bishop.
Thanks
1. Bf2 was my first thought. You're threatening 2. Ne3# and the Black king can't move, so he has to move the bishop. 1... Bd2 is the only move which doesn't lose immediately: 1... Bd4 loses the bishop and anything else allows 2. Ne3#. I guess after 1... Bd2 the king and bishop are close enough together to prevent the threats of forks or discovered checks which occur in the main line, which must be why that attempt doesn't win.
Okay
There's another interesting line after playing Bd4 while black has their bishop on e1. If they go Bd2, you have to play Bf2 and then regardless of what black does (as long as they don't trivially give the bishop away for free or allow you to checkmate with Ne3#), you have to play Nc3 with the idea of going Ne4, forcing black to give up their bishop due to the double mate threat.
Another small detail, that makes the position slightly less perfect (but still insanely impressive), is the fact on the 4th move white can play either 4.Be5 or 4.Bf6 - which are both equally winning with the same idea.
Another important detail is that the Knight on e4, also guards the Bishop on f2, ridiculous puzzle.
Thanks.
after 1.Bd4 Bd2 2.Bf2 Bc1 white cannot win. this puzzle is flawed.
@@Bhadrudu You play Nc3 - e4 threatening two mates in one. The only way to stop both is to play ...Bf4 thereafter you simply capture the bishop on f4 with your king. The bishop on f2 is now gaurded by the Knight on e4.
That was incredible. It's the kind of thing that makes chess such a magical game.
Bring back chess adventures please 😢

Great puzzle. I've found a great interest in your channel lately. You also have a great radio voice that captures the listener. Thanks !
Thank you Nelson, I love these presentations and also, your very cool delivery on the details!
Yeah I didn't solve that one funnily enough. Best puzzle I've seen in a long time.
7:14 is not zugzwang because if black is allowed to pass the move, Bg3 Kd2 Nc4 still forks
There is a Bd2 Bf2 Bf4! Nc3! variation that should probably be mentioned.
What about bishop f2 at the start? The black king can't move, the white king is on the light square, so you just move the knight around and give a check and mate eventually
1. Bf2 Bd2 2. Nb2 Be1 3. Be3 Bf2 and White has nothing.
Black plays bishop e1 and then it’s a draw
@@Connor-tw3uu 1. Bf2 Be1 2. Ne3#
Looks like a checkmate though?
Bf2, Be1, Ne3?
Bf2, Bd2. White can't go Ne3 due to black bishop
This puzzle is definitely a top 5 puzzle. Just insane!
Wow thanks for posting this puzzle :)
Excellent Nelson - thank you.
Great puzzle! Will have to rewatch a few times to remember it
Love your puzzles!! ❤❤❤
I cant see why bishop F2, Knight E3 does not win from the original position.
Nice information
The real puzzle comes right after winning the black bishop!
Hehe yes that’s why I couldn’t demonstrate it against my friends. They wouldn’t know bishop+knight is a forced mate and I wouldn’t be able to prove it.😂
Wow, what an incredible puzzle!
fantastic study !
😳that's a real brain buster Teacher Nelson 😮 COOL STUFF 😊THANKS.
Amazing puzzle!
No one annotates these intricate puzzles better than you do.
Domination!!
6:47 It's NOT zugzwang! If Black have option not to move, it's win for White anyway.
Because of Be5-g3+ Ke1-d2 Se3-c4+ fork.
Hey Nelson enjoyed this puzzle but why not initially Black moving the black bishop to D2 instead of E1 to threaten the square (e3) that the white knight could move to to check the black king?
I remember those good old videos of Martin challenges😢😢😢
How about Bishop to F2, then Knight to E3 check mate right off the bat?
I thought the same but black bishop to d2 will kill the idea and white has no mate solutions
Blacks Bishop to d2 stops it.
White moves Bishop to G2. Knight to E3. Checkmate
Would have been a great puzzle for chess adventures
I'd say the point if 2. Bd4 was to cover c3 rather than drop back to e5 - after 1. Bc5 Ba5 2. Ne3+ Ke1 White can still drop back with 3. Bd6, but Black can then survive with 3. ... Bc3. (Also, the line 1. ... Bd2 2. Bf2 followed by Nd1-c3-e4 feels worth discussing, and the position after 4. Be5 is still a win with White to move, through Bg3+.) Nonetheless, a great puzzle and video - I enjoyed it a lot!
The win Stockfish said I missed:
Charming endgame.
Stockfish keeps moving 1...Bd2, that isn't one of the moves you went over but the Analysis does give the solution.
I stopped everything and clicked 😂
What happn if you put bf2 1st and chakmate with knight i dont see any good moves form black
What's wrong with first move white Bishop to f2, followed by Ke3 checkmate?
4:08 You forgot to explain the outcome for moving black bishop to D2. Even though the result is still a loss, just faster :)
I still need an explain why Black wouldn’t play Bd2. I think it’s may be draw.
I've just checked the endgame database. The way to win after Bd2 is Bf2, trapping the King, end after the Black's Bishop moves, either immediate checkmate on e3 or reroute White's Knight d1-c3-e4 threatening checkmates on d2 and g3, forcing Black to lose his Bishop on f4.
Hello I am from Germany, watch your video and include it in my chess group. What if black moves the bishop to d2 ?
This is 10000 rating puzzle!
I thought everytime he would call himself Nelson he was referring to the bot and insulting himself
4:00 -- but what about *Bd2* for black ?? ... *Bb4* is ALSO a good resistance effort.
Yes, it's true: Black *eventually LOSES under optimal play by White...* ... but these are good moves to *PROLONG THE GAME AS MUCH AS POSSIBLE* , yet you didn't explore them AT ALL !! :O
.
If Bd2 then white plays Bf2 trapping the king. Black needs to guard e3 so they have to release control of c3 and e1 (preventing bishop trade). Then Nc3 - e4 threatening checkmate from d2 and g3. Black can only guard these squares by Bf4 sacrificing bishop (note that Be1 loses to Ng3). White king can safely take bishop because white bishop is protected by knight.
This was the my first thought before watching the video. Problem with playing Bf2 right away is that black can play Bd2 and white is in zugzwang.
Bishop b2, then horse e3, easier checkmate but black Bishop to d2 still stops both yours and this moves. From start.
What if black's first move is BD2?
Then Bf2 Bf4 Nc3 Bd2 Ne4 Bf4 (only square, where the bishop stops both, Nd2# and Ng3#, but now the f2 bishop is defended ny the knight, so) Kxf4.
Wow! Great, Nelson! Hope your health is improving?
From a quick look, seems like Bf2 and black has to give away their bishop to stop mate in 1.
You missed out Bd2 after white plays Bb6 in the video. Though it's still a win for white, it's not that straight forward.
"And after you win Black Bishop you will need to spend another 20-30 moves to checkmate with King-Knight-Bishop")))
- "It's well-known that Knight+Bishop is a win."
- "OK, prove it."
- *Starts to sweat profusely*
Yeah stopping what I was doing for that was a good decision.
As soon as i saw the puzzle my brain went back to "the horse does a W"
What about Bishop to F2 as the first move, the king is trapped and has no where to go with the follow on move of Knight to E3 check and mate. Black Bishop can move anywhere it wants but won't change the outcome. Unless of course I am missing something (I am still a beginner).
I was thinking the same, but black can counter with bishop to d2
Ye but what if Bc5, Ba5, Ce3+, Ke1 And finally Be7 with the intention of Bh4#
can you do fog war with martin
What about if Black play Bd2 after white's Bb6?
I admit I never had them patience to learn the knight and bishop mate.
The missed win stockfish tells me in game review:
Couldn't we mate in two with bishop on f2 and then horse e3
Why not put bishup infront of king and then bring horse to check mate bringing next to king. Bishop F2 at beginning. Then horse to e3
Why not Bf2 in the first move?
Bf2 as first move so the black has to sacrifice its bishop to impede the checkmate in the next move?
Bishop to d2 would stop the checkmate, and if you still gave a check with the knight, it'd lead to a draw
In that case, it's sufficient to move the knight in g4, controlling both e3, h2 and f2, the black bishop can't defend both e3 and h2 simoultaneously, if not the king can take it while the black king can't retake because the knight defends the bishop in f2. If the bishop defends the main black diagonal you can reach the checkmate aiming to e4 instead of g4 with the same result... Anyway you can reach the checkmate moving only the knight from the move 2
Why does bishop f2 not work?
What about bd2?
The board at around the 7:00 mark isn't a zugzwang for black, just a straight-up bad position. If black could skip that turn, they would still lose to the upcoming bishop check then knight fork.
yes it is...that's the whole point of a zz.....every move for black puts them in a worse position.
@@dagg310 It’s supposed to put black into a worse position, but black’s position is just as hopeless either way. Ergo no zugzwang.
Probably not important, but what could have lead to this position? What was black's last move? The king could have only come from e1. If so, why wouldn't he take the knight on d1 instead? If it was the bishop, black king could have just taken white's bishop on g1. I love these puzzles anyway. Thank you Nelson!
We're not going to mention that the position is only possible if the black king comes for the bishop instead of taking a knight, or if he moved the bishop last move and just didn't take the bishop
Black's last move could have been BxQc3. All White-to-win puzzles imply that Black had made a mistake at some point in the past.
Alternative title: the scummiest way to suffocate a bishop.
Solved puzzle 1 I think.
1. Bb6! (1.Bf2 is the idea, but then 1... Bd2 draws The thing is we have two threats in the original position. A mating net; and if you pay close attention, we are attacking the black's bishop.)
1... Bb4 2. Ne3+ Ke1 3. Nc2+ (forks king and bishop)
1... Bf6 2. Bf2 Bg5 3. Nc3 Bh6 4. Ne4 Bf4 5. Kxf4
1... Bd2 2. Bf2 (Now we achieve the position from my first comment, but with black to move. Black must either concede the c3 or the e3 square to the white knight)
Well I never saw in my minds eye all those disvered checks. I just said black cant go right because bishop controls the square. Was I blind.
Anyhow, my solution still looks correct even though you came up with with different solutions. My solution focusing on mate, while yours focusing on discovered checks to win the bishop.
The problem now is the one position I didn't analyze. After 1. Bb6 Be1 what now? Well...
2. Ne3+ Kg1 3. Ng2+ Kf1 4. Ba7 (Any bishop move along the diagonal to waste a move. except maybe e3)
4...Ba5 5. Bd4 ( and now)
5... Be1 6. Bb5 ( and win like last time)
5... Bd8 6. Bf2 Bg5 7. Ne1 ( and search for a checking square)
My dad and I were moving the aquarium from one place to another and halfway through I stopped doing it
my mind is blowed since a long time ! Chess is a divine game . God gave us this game
hmm looked at it and white bishop to f2 first move but then stalemate black bishop to d2 and so on
Me: reads the title
Also me: stops breathing
6:10 why not bishop f2?
Why cant you play BF2 for the first move
Scooby is so handsome!!!
We normal ppl cant even calculate that much
I'm early, and great vidoes!
What's about d2
Cant believe i just listened to a youtube video before i even clicked on it
how come there's no outro 😂
Effectivement
Challenge: Play against Martin, but you have to copy every move as black.
At the very beginning I would have offered a draw. Because even if i captured that bishop i dont even know how to mate with knight+bishop😂
If you think I'm going to make the same joke twice.
I will.
I was breathing until you said to stop what I was doing and now I'm watching this from hell. (Heaven had a "NO CZcams POLICY" so they kicked me out)
Couldnt you just start by moving bishop to f2?
Nvm they just move bishop to square knight will check and you lose
A random solving the puzzle: yeah! After ten hours finally I could solved it..... But I don't know the bishop and knight's mate
En effet
When chess adventure come back
why not White Bf2, then Black moves Bishop, next White move Ne3#
Why doesn’t bf2 work?
Coz black bishop to d2 will kill all your ideas
Burned my grilled cheese watching this video. Thanks Nelson.
what if black plays bishiop d2
I like these puzzles, but NOT the weird ones that never occur (24 pawns or 12 rooks....)..
Ok I did what title told me to do
Let's see...
Why wouldn't white's initial Bishop move be to C7? 😎
