Hallo

Welche Schachengine knackt folgende Stellung:



[Event "Sxe6"]
[Site "?"]
[Date "1990.??.??"]
[Round "?"]
[White "Rewitz, P."]
[Black "_"]
[Result "1/2-1/2"]
[SetUp "1"]
[FEN "8/5p2/4p3/2N2B2/8/2pRr1r1/2K1k3/8 w - - 0 1"]
[PlyCount "25"]
[EventDate "1990.??.??"]
[EventType "game"]

1. Sxe6!! fxe6 2. Lxe6 Txd3 3. Lc4 Th3 4. Lb5 Thg3 5. Lc4 1/2-1/2

Viel Spaß damit!!

Hallo,

Stammt das aus einer Partie? Wenn ja könntest du das ganze Spiel mal posten?

Danke

Hallo Ingo

Das ist eine Studie von Rewitz, P!

Fritz(10) frißt die PGN mit deutschen Figurenkürzeln nicht; hier eine andere:

[Event "Sxe6"]
[Site "?"]
[Date "1990.??.??"]
[Round "?"]
[White "Rewitz, P."]
[Black "_"]
[Result "1/2-1/2"]
[SetUp "1"]
[FEN "8/5p2/4p3/2N2B2/8/2pRr1r1/2K1k3/8 w - - 0 1"]
[PlyCount "9"]

1. Nxe6 $3 fxe6 2. Bxe6 Rxd3 3. Bc4 Rh3 4. Bb5 Rhg3 5. Bc4 1/2-1/2

Bei mir hat keine der Engines die ich probierte, das im Minutenbereich lösen können. Habe allerdings nur Pentium D. Einige Engines erkannten nach Vorgabe des ersten Zuges das Remis recht schnell (andere wiederum immer noch nicht)...

Salvete,

Entschuldigung, aber ich habs noch nicht ganz verstanden:
Was kommt nach 1. Sxe6 fxe6 2. Lxe6 Txd3 3. Lc4 Ke3 4.Lxd3 (was sonst?) Kd4?
Wie hält Weiß danach remis?

Viele Grüße reihum von

Nach Lxd3 hast du einen 5 Steiner (vorher halt 6er):



Gugst du hier:

http://www.shredderchess.de/online-schach/online-datenbanken/endspiel-datenbank.html

Kurz: ALLE legalen Schwarzen Züge sind Remis!

Hi Ingo,
guckts du hier: http://www.shredderchess.de  immer noch keine Ankündigung zum release von Shredder12 am Monatsende.

Hast du vielleicht nähere Info's?

Klar habe ich nähere Infos: Shredder hat noch NIE vorher angekündigt! Irgendwann ist S12 auf der Seite verfügbar.

(Na ja, vielleicht ist diesmal ja alles anders )

Upp's,
habe damals (Shr11, Nov.2007 ) noch keinen eigenen Internet-Anschluß gehabt. 

Stefan hat mir deshalb die Vers. 9, 10 + 11 jeweils extra auf CD zugeschickt!! Super Service!!  Danke nochmals dafür.

MfG

Vielen Dank für die Antworten - jetzt sehe ich das Remis
ebenfalls. Sehr schön, wirklich!

Danke auch für den Hinweis auf die Endspieldatenbank
auf der Shredder-Homepage - klasse! Die funktioniert
allerdings bei mir und meinem Firefox 3.5.3 nicht, nur
unter dem MSIE. Weiß jemand den Grund dafür?

Viele Grüße reihum von

Den Grund kenne ich nicht, aber an deinem Firefox liegts nicht! Den 3.5.3 habe ich auch und es läuft wie geschmiert!

Dankeschön! Unterdessen habe ich's rausgefunden, es lag
an Noscript, einem Firefox-Addon: Dem Noscript genügt
die Vorgabe 'Shredderchess.de erlauben' nicht, man muß
für diese Adresse zusätzlich 'sämtliche Beschränkungen
aufheben', dann klappt's auch mit dem Firefox.

Diese Endspieldatenbank ist ja wirklich sagenhaft! Was
es alles für unglaubliche Remisstellungen gibt - man
glaubt es kaum... Eine richtige Trouvaille für mich.

Vor allem: Du hast auch direkt von der Shredder GUI aus Zugriff darauf.
Zusammen mit der Joker-Analyse und dem Endspielorakel (einzigartige Features der Shredder GUI) bietet das phantastische Möglichkeiten.

Hallo

Gibt's Ergebnisse von SChachprogrammen? Zappa Mexiko II reagiert irgendwie völlig unverständlich... Nach 2 1/2 Stunden immer noch Lfh7 mit Bewertung. -2,9. Nach Eingabe von Sxe6 nach 20 Sekunden 0.00! Arena wurde vorher neu gestartet um nebenwirkungen zu vermeiden. Also wie kann's das geben, vor allem braucht Zappa nur Tiefe 15/29 um als Schwarz das Remis zu erkennen, aber hat als Weißer selbsr mit 24/58 noch keinen Plan...

Hallo Gerhard!

Im Antwortposting an Harun Taner dachte ich noch, es läge am Nullzug, liegt es vielleicht auch, weil immerhin schafft Deep Fritz 10 default nicht in 15 Min., was DF 11 mit Nullzug aus schafft, siehe unten.

bright 0.4 a hingegen, bei dem man den Nullzug ja nicht ausschalten kann ohne Eingriff in den code:

Neue Partie, Blitz:4'+2" Dort
8/5p2/4p3/2N2B2/8/2pRr1r1/2K1k3/8 w - - 0 1

Analysis by bright-0.4a:

1.Lh7 Th3 2.Le4 f5 3.Txe3+ Kxe3 4.Lg2
...
1.Le4 Tg5 2.Sa4 Txd3 3.Lxd3+ Ke3 4.Kxc3 Ta5 5.Lc2 Ta6 6.Sb2 e5 7.Sd1+ Kf3 8.Lb3 Tc6+ 9.Kd3 Td6+ 10.Kc4 f5 11.Kc5 Td2 12.Sc3 e4 13.Ld5 Kf4 14.Sb1 Tc2+ 15.Kd4 e3
  -/+  (-1.40)   Tiefe: 24/48   00:04:31  1742mN
1.Sxe6 Txd3 2.Lxd3+ Ke3 3.Sd8 Tg8 4.Sxf7 Tc8 5.Sd6 Tc6 6.Sf5+ Kf2 7.Sd4 Td6 8.Kxc3
  =  (0.00)   Tiefe: 24/48   00:06:19  2356mN
1.Sxe6 Txd3 2.Lxd3+ Ke3 3.Sd8 Tg8 4.Sxf7 Tc8 5.Sd6 Tc6 6.Sf5+ Kf2 7.Sd4 Td6 8.Kxc3
  =  (0.00)   Tiefe: 25/48   00:06:43  2480mN

Die hardware ist dieselbe (4x2,5GHz, 1536 Mb hash). bright greift dabei zum Unterschied von Fritz nicht auf die kompletten 5Steiner auf der Festplatte zu, sondern auf die, soviel ich weiß, auch für 5 Steine kompletten bitbases.
Mag sein, dass ihm das hier auch Geschwindigkeit bringt.

Hi Peter,

IIRC,

0.4a2 is the bug-fixed version of 0.4a.
0.4a2 had another bug relating to FRC part.
That bug was fixed in 0.4a3-frc.

==========================

20090401 version 0.4a3 (public)
==============================================================================
FIX: fixed yet another FRC castling bug, reported by Ray Banks
     Bright would sporadically castle illegally during it's search and crash.
     The situation occured when an enemy rook was 'hiding' behind the castling
     rook, putting the King in check after castling.
     This can only occur in FRC (not normal chess), for example:
     Rr2krnb/1pp1pp1p/6p1/3p4/3P4/1q2BN2/2bQPPPP/R5KB b kq - 0 21
     q5nk/5p2/1Q2p1p1/4P1P1/5P1p/1BR4P/8/rRK5 w Q - 3 80

FIX: The fix in 0.4a2 for FRC castling was ineffective for the UCI protocol.
     (the fix was good for Kc1'like moves, but did not detect e.g. d1c1)

This with 4x2.5 GHz, 1536 Mb hash and complete 5men_on_board tablebases on HD.

The point is, as to be seen on Fritz' PV, that the questionable 6_men_on_board_tablebase is not only 4 plies away as in main variant after 1... fxe6, but even 10 in this longer one of his. Within this some nullmoves don't make the position worse for any side.
Therefore I guess some engines would find the solution in reasonable time with complete 6 MOB-tbs, especially nullmove turned off.

That's why I switched off forward pruning too.

By the way I found several better achievements of cyclone solving problems with forward pruning off but did try this one with forward off only just about 15 minutes so I cannot say if maybe nullmove off was not really necessary here.
