Up Topic Hauptforen / CSS-Forum / Endspiel-Motiv Ungleiche Läufer...
- - By Walter Eigenmann Date 2016-12-30 11:32
.

Das Endspiel-Motiv Ungleiche Läufer ist ja ein Computerschach-Klassiker. Doch heute immer noch?

Scheint so. Stockfish 8 oder auch Komodo wollen mit Schwarz in der folgenden Stellung...



... partout die Türme tauschen, um mit dem (Doppel-)Mehrbauern zu gewinnen, was aber (trotz hoher Schwarz-Bewertung) nur Remis ergibt.

Der Mensch (v.a. wenn er S. Karjakin heisst...) knipst hingegen den Läufer sofort weg als die einzige wirkliche Verteidigung des Weissen, wonach der g-Bauer zu seinem schwarzen Umwandlungsfeld durchläuft:

http://www.glarean-verlag.ch/schach/Ungleiche%20L%C3%A4ufer/endspiel-motiv%20ungleiche%20l%C3%A4ufer.htm

Noch ist also das Compi-Schach längst nicht aus seiner "strategischen" Talsohle raus, und ein paar "menschliche" Vorzüge bleiben auch im neuen Jahr 2017 - guten Rutsch!

Na na na... auch "positive Ausreisser" gibt's immer, doch ich schätze mal, dass eine massive Mehrheit der 50 gebräuchlichsten Engines heute
das Stratagem dieser Stellung nicht kapiert bzw. deutlich länger als ein paar Sekunden für die Lösung braucht, während ein Meisterspieler
rein "intuitiv" und sofort das Qualitätsopfer in Erwägung zieht.

Houdine 5.01 spielt ...Td4:!  mit meinem Xeon X5680 in der Grundeinstellung nach 1:03 Min.; in der Tactical Einstellung (im praktischen Schach immer noch so stark
wie Deep Shredder 13) in 8 Sekunden.

Mit einem wenig schnelleren Computer wird der Lösungszug in Blitzzeittempo gelöst.

Trotzdem hochinteressante Stellung und Danke für die Einstellung.

Guten Rutsch ins neue Jahr !

Ich habe keinen Gewinnweg nach Txg7 gefunden, siehe hier:

Nur weil man den Gewinnweg nach Txd4 rechnerisch nachweisen kann,
heisst das nicht, dass er nicht strategischer Natur ist. Strategie ist nicht nur das,
was die Rechner unmöglich (oder fast nicht) berechnen können... Andernfalls verbanne man
den Begriff überhaupt aus dem (Computer-)Schach - was man IMO diskutieren könnte...

"GM Heine Peter Nielsen was not only Magnus Carlsen’s second in last year’s world championship contest but also had formerly served as trainer to Vishy Anand! So who better to present an overview of the recent Candidates tournament in which the Tiger from Madras, against expectations, earned the right to a return title match against Carlsen later this year. His wife GM Viktoria Cmilyte serves as co-writer and adds further colour to the report. "

{Diagramm [#] Black to move. What was his surprise continuation? [For a while
things looked rather grim for Karjakin. Svidler had obtained a promising
initiative for the sacrificed pawn, but Sergei defended stubbornly and took
his chances in the mutual time-pressure with a very strong 40th move. However,
most impressive of all was the following decision, when it already looked like
Svidler had found a good way to defend.]} 64... Rxd4 $1 (64... Rxg7 $2 65. Bxg7
g4 66. Kd2 $1 {would just lead to a drawn opposite-coloured bishop ending, as
when Black/^s king is on g2, White/^s stands on e1, and, as soon as Black
pushes ...g3, White answers Be5! and there is no way for the black pawns to
progress without White setting up a perfect blockade.}) 65. Kxd4 {Diagramm [#]
Black to play. Be precise with your next move!} b6 $3 ({This is the real gem!}
65... g4 66. Rxb7 g3 67. Re7 g2 68. Re1 {is similar to the game, but a much
better version for White where his counterplay is just in time.}) 66. Kc3 {
Diagram [#]} (66. Rb7 g4 67. Rxb6 g3 {is one important difference as with e6
being protected by the black bishop, White simply will not be in time to stop
the g-pawn from queening.}) 66... Ke3 $1 {[Another precise move. By
shouldering the king, Black blocks him from reaching e1 and White has no good
way to stop the g-pawn.]} 67. Rb7 g4 68. Rxb6 g3 69. Rd6 g2 70. Rd1 {Diagram

king is forced back to c3, which makes a decisive difference in the upcoming
race.]} g5 71. b4 Kf2 72. a4 g1=Q 73. Rxg1 Kxg1 74. b5 axb5 75. axb5 g4 76. c5

the white pawns, but despite being low on time Karjakin had calculated the
resulting queen-endgame very precisely.}) 78. b6 Kf2 79. b7 g1=Q 80. b8=Q Qc1+
81. Kd4 {Diagramm [#] Black to move. What tactics can he employ to clinch the
win?} Qe3+ $1 82. Kc4 (82. Kd5 Be6+ 83. Kd6 Qf4+ 84. Kxe6 Qxb8 85. Kd7 Qb5 $1 {
stops the c-pawn from advancing, and thus wins easily.}) 82... Be6+ {[Forcing
the white king to the b-file, where 83...Qb3 picks up the white queen. Svidler
resigned.] In the next round, against Kramnik, Karjakin exploited an early
blunder by his opponent to win a couple of pawns and, with two wins in a row,
from being an outsider he suddenly had a realistic chance of fighting for one
of the top places. The 9th round was crucial for Anand/^s lead. While his two
closest rivals, Aronian and Kramnik, lost, Vishy managed to win an important
game against Topalov, which gave him a 1 point lead over Aronian and at least
11/2 points over the rest of the field.} 0-1
Parent - By Michael Scheidl Date 2016-12-30 23:03
Ja, bin überzeugt. Sensationell gut von Karjakin gespielt! Inzwischen leuchtet mir auch das sozusagen strategische Element (oder das positionelle, oder wie immer man es nennen will) ein. Aber Engines sind hier auf jeden Fall auf Berechnung angewiesen, denn ein etwaiger Penalty für ungleichfarbige Läufer wird sicherlich viel geringer sein als eine Qualität.

Ich mit Schwarz hätte mich vermutlich nicht getraut Txe4 zu spielen.

P.S. Sehe gerade, die Stellung hatten wir im Forum schon und offenbar spielt der Oldie "Der Bringer" das Opfer auch bald. Nette Sache.

Klaus Bischoff vs Guenter Stertenbrink
Bundesliga 8687 (1986)  ·  Sicilian Defense: Hyperaccelerated Dragon (B27)  ·  0-1

nach 55...g5



Weiss am Zug , welcher Zug haelt remis ?
Klaus Bischoff hat's nicht gesehen und ich auch nicht,
hatte ich doch noch mit Bodo Schmidt gewettet, ( Porz spielte parallel
und lauerte auf einen Ausrutscher der Bayern)
