New Chess Endgame Record
From Marc Bourzutschky, a new chess endgame record: a certain position with king, queen, and night versus king, rook, bishop, and knight requires 517 moves to win. And here "win" doesn't even necessarily mean mate, it just means mate or capture of a piece, thus reducing to a simpler endgame. This kind of complexity is reminiscent of the complexity generated by the busy beaver problem, reminding us that simple systems can lead to all kinds of complex behaviors.

Matt in 530 Zügen - Wer kann es lösen ?
Weiss : Kd2/Dh1/Th4/Le3/Sb6/Sh2/c6/e6 (8)
Schwarz : Ke5/Dg3/Te7/Tg7/Lb3/Sf6/Sg5/d7 (8)
Lösung :
1.Lf4+! Dxf4+! 2.Txf4! Kxf4! bis hier noch einfach. Doch welches ist der RICHTIGE 3.Zug von Weiss ? Hier kommt erst einmal ein falscher 3.Zug ( eine Neweklowsky-Verführung : 3.Df1+? Kg3 4.c7 Sge4+ 5.Kd3 Kxh2 6.c8D Tg3+ 7.Kd4 dxe6
8.Dh8+ Th7 9.Dxh7+ Sxh7 10.Kxe4 Ld5 11.Ke5 Sg5 12.Df2+ Kh3 13.Sxd5 exd5 14.Kxd5
und wir haben ein klassisches Remis aus der 5-Steiner-Datenbank. Jeder sollte diese Verführung ruhig einmal in seinen Computer zum Testen eingeben ! Also , welches ist nun der
richtige 3.Zug von Weiss ? Die Lösung geht wie folgt weiter : 3.exd7! Sxd7! 4.cxd7! Txd7+! 5.Sxd7! Txd7+! und was jetzt ? Allein mit dem Zug 6.Kc3 !! geht es jetzt zum Gewinn ( aus der 7-Steiner-Datenbank ) Unter http://www.xs4all.nl/~timkr/chess2/diary_16.htm
kann man ersehen was passiert : 522.Dxg5+! und jetzt sind wir in der 6-Steiner-Datenbank und es Matt im 530.Zug. Mein Problem setzt einfach 4 Züge vor eine 7-Steiner-Datenbank.

I wrote 2 different programs for the #530 :
1.Program : generated from the beginning AFTER 5. ...Rxd7+! ( minimaxes DTM over all winning lines ) with 6.Kc3!
2.Program : only for starting position from 1.Bf4+! Qxf4+! 2.Rxf4! Kxf4! 3.exd7! Nxd7! 4.cxd7! Rxd7+! 5.Nxd7!Rxd7+! ( != there exists no other possibilities )
My worldrecord from the 6-men-endgame-database in wikipedia ( http://en.wikipedia.org/wiki/Chess_problem ) with #267 is composed in the same way of generating.
For example here 2 wrong ways in the #267 to understand what I mean :
1.Bxg2+? Kxg2 2.Qxf6 Bxf6 3.Rxg1+ hxg1D 4.Nxg1 Bxd8+ 5.Kxd8 Kxg1 ( you have KRN against KNN with remis-position ) or
1.Bxg2+? Kxg2 2.Qxf6 Nxf6 3.Rxg1+ hxg1D 4.Nxg1 Bxd8+ 5.Kxd8 Kxg1 ( you have KRN against KNN with another remis-position )
and now the only correct way to mate :
1.Qxf6! Bxf6! 2.Bxf6! Nxf6! 3.Bxg2+! Kxg2! 4.Rxg1+! hxg1Q! 5.Nxg1! Kxg1! ( you have now KRN against KNN with the only winning position )
So my 2 unbroken worldrecords are coming from the mixtur of two things : 1.Generated databases with the help of computers and 2.Chesscomposition from the human brain , checked by computers.
