Rybka which claims to be best Chess program was beaten by Beginner

Rybka played wrong move thinking it will Mate in 2/3 But the King was
saved and Rybka Resigned saying Unable to Respone.

Sanny, I think you are misinterpreting the
program's behavior here. Unless it actually
"resigns", you cannot take the reins and
resign for it just because you want to, as
you so often have in the past-- even for
human players.


Rybka was playing at Hard Level and Beginner was playing with Black
Pieces.

This show Rybka is not Strongest Chess Program in the World as
Beginner Level was able to beat it.

I recall that Zappa beat Rybka in some recent
event, but it mainly showed that the other
program's openings book guy won a single
battle against Rybka's opening's guru.


I suppose GetClub is now as good as Rybka .

That would be wrong.


Is there any other
Program better than Jester and Rybka.

Try playing a game out, to the actual finish
against Rybka, and see what happens.


As GetClub Beginner Level has
beaten Both of them once. Both claim at their site they are the Best.
But then why Rybka lost to Beginner Level.

You are the only one who believes it did.

The rest of the world will see this as just
another "boy cries "wolf!" posting.

Things don't look too bad for the GC program
here. At this quick rate of play, Rybka went
after a pawn (g7) which would have opened a
file for attack on its own King.


15. Qg5-e5{14} Ne4-f6{6}
16. Bc1-f4{18} Qd6-d7{6}

A horrible strategic error. Black ought to
have fallen over itself to trade Queens, in
view of the severely compromised pawns
in front of its own King. Now White's
attack easily crashes through.

This is a forced mate, and in such cases,
a few programs "freeze up", just displaying
the next move in sequence. I hate this, but
don't know if it is a flaw of the engine itself,
or another "interesting facet" of the GUI; in
my case, that would be Arena.

The longest mate goes as follows:

20. Rb1+ Ka7

21. Be3+ c5

22. Bxc5+ Bxc5

23. Qxc7+ Ka8

24. Qb7++

1-0
