Chess problem 28 / Schachaufgabe 28
English
Finally weekend is coming, so I guess the chess friends around here may enjoy it to take their time, put up their chess boards and maybe a cup of coffee and try to solve my next chess quiz. :)
This time I present you a position, in which white found a really very elegant way to checkmate his opponent within only four moves! Who did play these nice moves? Was it me? Was it any famous grandmaster? No, the position arose in one of my chess software test games between "Ruffian 1.01" and "Ktulu 4.0". Even if computers may have no sense for aesthetics, sometimes they create it unintentionally, just by calculating. Actually this exact computer chess match mentioned above, produced so many fantastic games that I may chose another position from this competition as one of my next chess challenges again.
Your task is it now to be at least as good as "Ruffian" and find the fastest checkmate as white! :)

Endlich naht das Wochenende, und ich vermute, die hiesigen Schachfans dürften mal wieder Lust dazu haben, ihre Schachbretter und vielleicht eine Tasse Kaffee aufzustellen, um zu versuchen, mein heutiges Schachquiz zu lösen. :)
Dieses Mal möchte ich euch eine Stellung zeigen, in der Weiß einen wirklich sehr eleganten Weg fand, seinen Gegner in nur vier Zügen schachmatt zu setzen! Wer spielte diese schönen Züge? War ich es? War es ein berühmter Großmeister? Nein, die Position entstand in einer meiner Schachsoftware- Testpartien zwischen "Ruffian 1.01" und "Ktulu 4.0". Auch wenn Computer möglicherweise keinen Sinn für Ästhetik haben, erzeugen sie sie zuweilen ungewollt durch pures Rechnen. Gerade dieses oben erwähnte Computerschach-Match führte zu so vielen wirklich großartigen Schachpartien, dass ich sehr wahrscheinlich eine weitere Stellung daraus für eines der kommenden Schachrätsel auswählen werde.
Nun gilt es, mindestens so gut wie "Ruffian" zu sein und mit Weiß in spätestens vier Zügen matt zu setzen! :)
Rg7 Bxg7 2. Rf5 Bh6 3. Ng6+ Kg3 4. Rf3#
Rg7 Rd5 2.Rf5* Bxg7 3. Ng6+ Kg3 4. Rf3#
* I know Rxf5 Nxf5# is a possibility.
I started working on 1.Rf4 but seems black has plenty defenses, but Rg7 is a really surprising attack, following the first Rook sac with Rf5 is impressive.
Congrats - you are the winner of this round!
I have to say I found 1. Rg7! really so impressive when Ruffian "pulled this rabbit out of the hat"! :)
I found Rf5 more impressive, seems Rf4 is more natural, I am posting a classic puzzle will be up soon you might want to check it out.
Rf5 is a consequence of Rg7 though, but indeed a great part of the winning path. :)
I think 1. Rg7 is just fantastic: its sense is that after Bxg7 later black cannot control the g6 square any longer by playing Rg8, because the own Bg7 blocks it.
Ok, I may check your puzzle, and I am sure you will reward me with a 100 % upvote in case I solve it, will you? :)
Brilliant. Look like a master of chess
Not as brilliant as your introduction post, my friend. :)
Nice to hear it look forward of your post
Black will answer 1. ... Kg5 (1. ... Kg3 is not possible anyway).
Didn't see that Kg3 not possible because of Nf5. It's hard to imagine where the pieces are when they have been moved.
Yes, needs some practice ... :)
That's the quickest way, it is possible because I'm playing both sides.
But why should black play Kh4-g3?!?!? :-)
Because he wants to lose the game the quickest way.
Ng6!! Kg5, Why g5? There are two squares for the king left only. But King can't go to g3 because of Rf2-f3!!
So he goes to g5 but this place is full of poison too because next step of white is
Rxf6
Now there is no way out for the black king. Black's next draw doesn't matter at all. Next draw of white will be the end…
Rf2-f5!! exitus
It was a little bit easy, @Jaki01…
Where are all our chess champions?
It is NOT yet solved! :)
1. Ng6 Kg5 2. R7xf6 Bg7! (Black can escape to h6 now.)
How can you checkmate in two moves now, my friend?!? :)
There is one short sentence, @jaki01: „I surrender!“ But you love to go the hard way. Thanks. My proposal was no checkmate in 4 moves… I have to think about…
Ich dachte, sowas gehört gar nicht zu deinem Wortschatz! ;)
Das habe ich dir nahegelegt, lieber Jaki. Mit den neuen Zügen habe ich Lösung ja wohl auf dem Tisch…
Yes, the pawn is strong of course.
Ng6+ Kg5
h4+ Kxh6
Rxf6+
Und nun? :)
Ja, der Springerzug war falsch… Besser:
Nf5+ Kg5
h4+ Kg6
Nxh6 Kxh6
Rxf6#
Statt 3. ... Kxh6 spiele ich 3. ... Rd6. Wo ist das Matt? :)
Ich habe vergessen, dass die Aufgabe lautet , in vier Zügen. Da wehrst du dich natürlich auch, wenn es keinen Sinn mehr macht. Also anders lösen. Ach ja, viel besser…
Ng6+ Kg3
Rf7xf6 egal was jatzt kommt
Rf2-f5#
oder
Ng6+ Kg5
Rxf6 egal was du nun tust nächster Zug
Rf2-f5#
Mann, war das wieder einfach und doch so schwer.
e7-f5
h3-h4
Good try, but finally not fast enough. Lets see:
Now two more moves are left to checkmate ... how? For example:
Ich begreife diese symbole nicht.
Ja ich wollte dann mit dem Pferd nach h6 und dann mit dem turm nach f6.
4 züge matt (?)
7E to f5 ?
Or 7e to G6
King h4 to g5
tower 2F to 5F
kinda late and totaly wrong xD realy genial chess quiz
Try again tomorrow. ;)
yeah would be a good idea
