Houdini Chess Program Crushed!! - Using The A.R.B Chess System

http://www.youtube.com/watch?v=v1fVAALg7tc


Regards Anthony.R.Brown

Here is the game. No information is available about the hardware on which Houdini ran, or the settings assigned to the engine. No information about time taken to move, by the engine or its human opponent.

As was pointed out at TalkChess, Houdini missed the winning 19. Bxb5, so it was not searching deeply at all.

A System this Profound! needs to be shared! For those who cannot use YouTube, I offer the following excerpt:

Excerpted from http://www.youtube.com/watch?v=v1fVAALg7tc

Anthony.R.Brown 27/07/2013 (Great Britain) [email address removed]

How to play the System...

(1) The Main idea of the System is to Cramp your Opponents Position! Drive them back
and limit their Opportunities!
The System came about because of the Growing Strength of Chess Computers!
Now the Best in 2013 are Rated at 3000+ ELO Stronger than any Human in history!
the System works because the Chess Game Tree has not been Solved?

(2) The Pawns are the Soul of Chess! By the famous François-André Danican Philidor
[link to wikipedia removed]
and Never! more so than with (A.R.B.C.S)

(3) The Majoroty [sic] of Blacks Pawns are developed before the Pieces one square third
rank.

(4) The Knights are developed on the Centre squares second rank and act as
Guardians to the Pawn structure...and only as Attack Pieces if the reason is Good.

(5) The Bishops are developed on the diagonal second rank squares and act as
Skewer's slicing through the Board waiting for Prey!

(6) The Rooks can be used as Sacrificial Pieces because the Pawn structure that
develops weakens them...and of course if the reason is Good any Piece.

(7) The Queen! is the Queen! And can Dominate Closed Positions so look after her!

(8) The King Rules...but only if he has loyal followers...So Protect him well!

(9+) There are many more ideas/rules contained within the System...a Book is needed
to describe everything...maybe that will be next on the list.

OK!...

So it has been pointed out that at move (19) Houdini-White should have Played Bxb5 instead of B-b3 ?

The game was played at 60 seconds each per move...and that's why Houdini did not find the move!

So how long do we wait for a Computer to find the Best move in any Position?.............................

To find the move Houdini would of had to search to 23/65 not possible in the Game with the time controls set...

Plus more important a lot of the Computers previous Analysis was waisted looking at the wrong Black replies!?

The Analysis can now Start to see if Black can Win by not Playing 18-b5 and playing a better move!

This can of course go on forever until the end of the Game Tree ? until every variation has been played...Then Humans will Stop playing Chess!!

As was pointed out at TalkChess, Houdini missed the winning 19. Bxb5, so it was not searching deeply at all.

The Important thing is that We Both Played at the Same Time Settings! 60 Seconds Each Per Move! Fair Game!!

So ask Houdini ?

Below are the Moves as Played in the Game!...
So its Easier to Duplicate the Game Against Houdini.
Set Houdini's Thinking time to (60) Seconds Fixed.
You should also try to Play at about the Same Speed!
If you Play too Quick! it may Change the Response Moves by Houdini ?
P.S you may have to Enter the First (2) Moves Each as the Opening Choice for Houdini!
as that was it's Choice for the Game.
