Some research, but the idea was to make me a stronger chess player, so you have to wonder whether it was a waste of time. 

Back in the days when chess openings books were mostly descriptive and of the P-K4 variety or a mass of indigestible ECO data I typed out a complete ECO classification with the move sequences and names of the openings. It took me ages. I just now checked my classification to find the name of this opening. It was blank. 

So I looked up a book and found that it is the Blackmar - Diemer Gambit Accepted Euwe Defence. A backwater of D00 with a very distinguished name.

These days ECO classifications are ten a penny and you can find a good one here :-

(Long ECO codes zip file)

I even found a Blackmar-Diemer fan website.

We live in a time when a five minute Google search is the equivalent of a week spent in a reference library, twenty years ago.

All the best

Mike,

Quote from: Mike Watters on January  8, 2006, 06:17AM   

I have seen lots of references to Rbyka but this is the first game I have seen. It is a beautiful demolition. Up to and including move 7 ... Qxf6 the moves have been played many times but 8 Bb5+ I couldn't find in Chessbase 8 at all. Once the critical position is reached Fritz 8 and Pocket Fritz 2 play 9. 0-0 quite quickly sacrificing the bishop for the f and b pawns and the attack.

As for PSH I have no idea what the initials mean.

All the best
Mike

The German chess computer forum that one of Ismenio's links refers to explains it as „Pre-Scan-Heuristic“ or „Pass-Sicher-Halbwegs“, which still does not ring any bells to me, not even tiny Glöckchen

By the way, Rybka may be strong enough to beat Fritz, so far it has all the time been beaten by another program, which is extensively being advertised on eBay. You may guess twice which one that could be ...

You seem to have done quite a bit of research. Have you got any idea what the name is of this gambit (1. d4 d5 2. Nc3 Nf6 3. e4 ..)? I am curious to know more about it (characteristic of weak players ).

As always, I loved the pictures. Also the note on the cardboard chess computer:

- a chess computer made of cardboard that I received because I am supposed to have something with these machines.

LOL!

On the celebration of St Nicolas (5 December), the Dutch customarily give each other presents, which are often accompanied by rhymes and so called surprises. These surprises are home-made contraptions which often symbolize something connected with the receiver (or better: the victim). Just to give you some impression: these are the surprises that the members of the Overtom family gave each other two years ago:



As you can see, one of the surprises was a chess computer made of cardboard. You may guess which of the family members this surprise was meant for. You can read more about this quaint Dutch custom at:

        overtom.nl/weblog/31DEC03.html

Why do I mention these 5 December surprises?

Not primarily because I also wrote an article named "Surprise" on this forum on 5th December ([url=http://users.boardnation.com/~chesscomputers/index.php?board=1;action=display;threadid=603]http://users.boardnation.com/~chesscomputers/index.php?board=1;action=display;threadid=603[/url]

No it's because I recently read the December issue of Dutch chess computer magazine "Computerschaak". One article was written by Cock De Gorter, a Dutchman who contributed to several chess programs by assembling their opening library. His article was entitled 5 December Surprise.

Cock (yes, that's really his first name) describes how he often visits the Playchess server. On the night of 5 December he sees a chess program called Rybka written by Hungarian Vaclav Gerard Rajlich. Cock expresses his surprise about the fact that Rybka evaluates about 50,00 positions per second, which is relevant if we consider the one million positions evaluated by Fritz in the same time.

The games that Rybka played, reminded me of the discussion about PSH. For instance, in the article by Thorsten Czub, we can read that PSH should enable computers to "sacrifice a piece or give pawns for a good position and an attack".

But isn't it said that one game may say more than a thousand words? So have a look at the game below and see for yourself the way in which Deep Fritz 8 (!) is beaten by Rybka 1.0 beta:

[White "Deep Fritz 8"]
[Black "Rybka 1.0 beta"]

1. d4 d5 2. Nc3 Nf6 3. e4 dxe4 4. f3 exf3 5. Nxf3 e6 6. Bg5 h6 7. Bxf6 Qxf6 8. Bb5+ c6 ..

                           

What follow now could have been played by chess magician Michael tal: 9. O-O! cxb5 10. Ne5 Qe7 11. Nxf7 Rh7 12. Nxb5 g5 13. Nbd6+ Kd7 14. Qd3 Rg7 15. Rae1 Nc6 16. d5 Kc7 17. dxc6 h5 18. Qg3 e5 19. Rxe5 Qxd6 20. Nxd6 Bxd6 21. Rf6 Black resigns.

Best regards,

tom

Hello Ismenio,

Thank you for your response.
Badly, I knew these 2 links, and the most interesting is
in German, that I don't understand.
However, I'll try to translate it with Google (I know,  because it is not my first try, that Google's translation is sometimes very funny, and need a good knowledge of the subject to obtain a good ROI (return on investment)).
If ROI is good, I'll write it here.

Olivier.

Hi Oliver,

I only found this on web that has some reference to it: http://www.rebel.nl/tczub.htm (By Thorsten Czub).

Also a thead on Schachcomputer.info with some notes:
http://www.schachcomputer.info/forum/showthread.php?p=3274#post3274

But I would be interested in knowing what you find.

Hi, reader (and acrobat ?  )

First, happy new year 2006 !!!
Second, a very very happy new year 2006!!!!!!
Then, the question like a C program with only commentaries on it : 

main()
{
/* Do you have some informations about the PSH stategy
    that Mr Kittinger created for the superconstellation ?
    Do you know the concept behind theses 3 letters ? */
}

Thank you,
Mychess.
