***The BUG of Shredder***
The NOSE of Shredder at the WM 2003!? Only enclosed: I wrote further down (to
Thomas Wallendik) that also the operators decide whether it a portion give up or
not! Naturally for this the agreement of the tournament line applies. How I read
in another place, the operator of Jonny wanted to further-play against Shredder
(despite 3fach repetition of course) and it implemented its course already, and
went only then to the tournament line. As he now however said, that was (more
ignorantly) an error of it, because he wanted to decide in agreement with the
tournament line. Since it gave however the course right up, the tournament line
could not accept differently than the victory of Shredder later. Strange way
however the tournament line in the portion Fritz accepted vs. cunning (after a
matte announcement of Fritz) the task of cunning, although it had been a long
forecast matte. One could itself have let the matte from Fritz also here show?
but one trusted the matte announcement. I remember however the fact that Diep a
portion up to the matte to play had (believes against Brutus). Result: The
operators with agreement of the tournament line decide, when it is
further-played and when not. On a Remisangebot the engines in any window to wait
is not necessary. So seen, we saw therefore (because of Play off) altogether 13
Fritz and Shredder portions, and there the computers (particularly of Fritz)
with 4x 2.8 GHz the straight slowest was not, were also the Play Offs with
60?/Partie on a high level in the comparison to the SSDF or a dual computer!
Shredder lay in the fine valuation after 11 rounds in front. Fritz won the
direct 1st comparison however. Shredder won however the hochklassige Olay off.
Thus Shredder of the correct, worthy, and correct world champion 2003 is! But we
come to nose. What was there the matter? If it did not receive someone on
Saturday, which is said that Shredder in the portion against SOS likewise a
2fache repetition of course played, and that there was no 3fach repetition to
register already here, it is only because of the lucky circumstance that
Shredder the 2fache repetition introduced and not SOS! Here the 1. Position:
Parsos vs. Shredder
[ D]8/5rkp/3p2p1/Q2P4/6q1/8/6P1/R6K b - - 0 1
49.Dxa5 Dh4+ 50.Kg1 Dd4+ 51.Kh2 Dh4+ 52.Kg1 Dd4+ 53.Kh2 De5+ We see here that
black with the zugfolge 49... Dh4+ a repetition of course made. To determine
thereby the following factors are: Black chess offered and the opponents played
thereafter with its king on the same field back where it before it chess had
gotten. Now the 2. Position against Jonny: Shredder vs. Jonny
[ D]1rr5/p4q1k/3Q4/8/4p1R1/2p5/PPP1B2P/1K6 w - - 0 1
Here it was the opponent of the one 1. Position against getting introduces, by
means of Tab8! And which makes Shredder? It behaves just as in principle as
against SOS and plays a double repetition of course from its view: 33.Tg4 Tab8
34.Th4+ Kg8 35.Tg4+ Kh7 36.Th4+ Kg8 37.Tg4+ Kh7 After the black course 37. Kh7
developed a 3fach repetition of course, since she was introduced by the opponent
of Shredder, in contrast to only the 2fach repetition in the portion of SOS vs.
for Shredder. What is noticeable? We are not in the final game. I.E. that the
repetition of course cannot have to do anything with the Tablebases. Identical
here however the same motive is as in the SOS portion: Shredder gives a chess,
which opponents plays a course later with the king on the same field where he
before already was, and Shredder gives there 2. Times chess. Now I looked for
all Shredder portions of the WM for the same motive, and I found an interesting
position! In the portion Shredder vs. Brutus (round 5) came it to the following
position: Shredder vs. Brutus
[ D]1q3n2/8/pk1p3P/1p2p3/4B3/P7/1PP5/1K4Q1 b - - 0 1
We are in 39. Course and Shredder give Dg1+! But which follows now? This
zugfolge: 39.Dg1+ Kc7 40.Dg7+ Kb6 41.b4 We see here clear parallels for the two
previous examples to course 40. Shredder gives chess, which plays king after c7,
then Shredder 40.Dg7+ now plays and happened in principle the same pulls as in
the previous examples, Brutus its king on the same field where it with first
chess requirement of Shredder lay. Now does the simple question arise to me, why
Shredder did not order the program this NOSE still times on g1 chess if had,
that the samples are identically?? Eduard World:
