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

[@lajos-berenyi]

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.

Great puzzle. I've found a great interest in your channel lately. You also have a great radio voice that captures the listener. Thanks !

[@dentonyoung4314]

That was incredible. It's the kind of thing that makes chess such a magical game.

[@UndeadFil]

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.

[@shoopi1234]

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.

[@CarlosSamuel-ms9ee]

Another important detail is that the Knight on e4, also guards the Bishop on f2, ridiculous puzzle.

[@NidusFormicarum]

Thanks.

[@Bhadrudu]

after 1.Bd4 Bd2 2.Bf2 Bc1 white cannot win. this puzzle is flawed.

[@NidusFormicarum]

@@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.

[@escapedlunatic27]

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.

[@luqmaanhay4957]

Okay

[@Lucashallal]

It’s funny that if it was black’s turn again after Bd2 than this would be a win with Nc3, threatening a double checkmate threat in e4. It’s zugzwang for both sides. In fact, this line is important for ruling out Bd2 for black in a couple of other places in the position, as white could then play Bf2 and it would be black’s turn. Mindboggling!

[@roblodocus2539]

This puzzle is definitely a top 5 puzzle. Just insane!

[@terryhayward7905]

I cant see why bishop F2, Knight E3 does not win from the original position.

[@Lucashallal]

Bd2

[@premierkg7822]

@@Lucashallal then Knigh simply travels to F5, then checkmates. It's much easier.

[@Lucashallal]

@@premierkg7822 It’s been awhile, but I remember that the position after Bd2 is a zugzwang for both sides, so that is why we have to go the long way to ensure it is black’s turn when that happens. Otherwise there is some weird defense I don’t quite remember for black (probably involves the fact that no matter where we move, black will have free choice with the bishop, as opposed to if they moved first and had to choose some square to defend and leave another one free to us). It is a truly fascinating position!

[@msjoanofthearc]

Thank you Nelson, I love these presentations and also, your very cool delivery on the details!

[@muskyoxes]

7:14 is not zugzwang because if black is allowed to pass the move, Bg3 Kd2 Nc4 still forks

[@amrutagaikwad8400]

Nice information

[@cwalenta656]

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?

[@Lucashallal]

Than we play Bf2 and it’s zugzwang for black, since they can’t stop us from playing Nc3 next, threatening e4, which would be an unstoppable double checkmate threat. The reason Bf2 doesn’t work in the beginning is because after black plays Bd2, it reverses and becomes zugzwang for white instead, since we have to play Nb2 and they play Be1, defending everything. It’s fascinating!

[@rachanabhandari4585]

I remember those good old videos of Martin challenges😢😢😢

[@adamfysh-foskett961]

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!

[@lethihaiyen4762]

Why cant you play BF2 for the first move

[@stanimir5F]

This is 10000 rating puzzle!

[@alyvav.trauma2440]

4:08 You forgot to explain the outcome for moving black bishop to D2. Even though the result is still a loss, just faster :)

[@viang7300]

I still need an explain why Black wouldn’t play Bd2. I think it’s may be draw.

[@karelspinka3031]

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.

[@dmaster20ify]

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)

[@dmaster20ify]

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)

[@qazzaqstan]

[@vtgrphy3907]

How about Bishop to F2, then Knight to E3 check mate right off the bat?

[@Dandanukadan]

I thought the same but black bishop to d2 will kill the idea and white has no mate solutions

[@kimbirch1202]

Blacks Bishop to d2 stops it.

[@Lucashallal]

That position with black’s bishop in d2 and ours in f2 is a zugzwang for both sides, explaining why Bf2 doesn’t work initially and also why black can’t go to d2 after Bb6 or Bd4. It’s an amazing position

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 .

[@bloak9803]

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.

[@rajatdogra96]

I stopped everything and clicked 😂

[@cowebb2327]

What's wrong with first move white Bishop to f2, followed by Ke3 checkmate?

[@antog9770]

Bf2 as first move so the black has to sacrifice its bishop to impede the checkmate in the next move?

[@someoneelse1942]

Bishop to d2 would stop the checkmate, and if you still gave a check with the knight, it'd lead to a draw

[@antog9770]

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

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?
