SF6 moves comparison: Event Vugar Gashimov Mem 2015

[Dann Corbit]

...
I am doing a study on Paul Morphy right now. At current depths (probably 30 plies average) there is a 55% hit rate with Stockfish move choice {at that depth}. About the same as Eichborn (but I eventually analyzed Eichborn to about 35 plies and I am not there with Morphy yet).
...

You mean the Eichborn (Louis) whose ficticious games were made up by CB? It is not even sure the person did exist in reality and his personality
is just a fiction but gratefully accepted by the internet after all informations where gone?

Guenther

I saw some of his game scores in very old books. So if CB did make him up, then they also own a Tardis and are friends with Dr. Who.

very old books from what date?

It is the first time that I read about this player

I found that he has a value in wikipedia

http://en.wikipedia.org/wiki/Louis_Eichborn

The books are old and copyright has passed so the quotes are easy to find by web search now.

https://books.google.com/books?id=lCkCA ... ch&f=false

https://books.google.com/books?id=EWEzA ... ch&f=false

https://books.google.com/books?id=0bw3A ... 29&f=false

https://books.google.com/books?id=ha1AA ... 29&f=false

Deutsche Schachzeitung volumes 48-49 is probably the most interesting because it records three of his games against players other than Andersson

So no proof again he ever played Anderson?

Guenther

There are Andersson games in the those citations as well. Take a look. Those games are easy to find. The games against other opponents are much harder to come by.

There is a hypothesis that Eichborn only recorded his wins and draws which explains the absurdly good record against Andersson. But there is no proof of that conjecture. So it is entirely possible that he was the greatest chess player of all time.

You might want to try. Tested in windows 7. Prepare your engine, I only test this on sf6. If you try other engine use first a fast time say 0.05 sec or 50ms.
The epd file is also included, this is only up to 3 rounds. This epd file is specially generated from pgn with move time info taken from chessbase playchess site.

There is a hypothesis that Eichborn only recorded his wins and draws which explains the absurdly good record against Andersson.

This is probably more than a mere hypothesis, it is rather likely. Wildhagen in his "Weltgeschichte des Schachs, volume 4. Anderssen I, 1968" writes: "It may come as a surprise to many that this collection contains more lost games by Anderssen than one might expect. v.Gottschall as early as 1912 explained that Anderssen did not write down the games himself. His partners have recorded mainly games in which they succeeded in making a draw or achieving a win against the famous master." Wildhagen mentions Eichborn's games as an obvious example.
I think this quote is of interest because Wildhagen and the editors of the "Weltgeschichte des Schachs" (world history of chess) put a lot of work into their project, it is more than a random opinion.

Again a nice tool Ferdinand..Thanks

Do you have also a tool that makes these .epd files from .pgn like you do now?!

Then we can use this for any tournament..and i was thinking for my engine testings to see how many moves each new compile or different engines think on same moves..

I am using python chess library 0.7.0 to convert the SAN move to LAN move which is the only thing special in this epd. The uci engine will output move in LAN format so it is easy to compare moves. I am not sure if you are willing to install that library together with python 2.7.6 which I have been using. That epd is also from a pgn with time info in the move like the following. I am not really willing to share this unless you know python programming. It was just unfortunate that I cannot convert the script to exe, I could have shared it without much inconvenience to the user. When using that python libary, the py2exe program will fail to convert. Other tools I share in exe are from python script but not using that library.
Send me your interesting pgn file, and I will convert it. Not really the big files, this is basically intended for human tournaments. Perhaps the KK matches, or some human tournaments in the past. I will create a new version that will not consider time in the move on the games.

Thanks Ferdinand ,this goes to far away from my knowledge..i don't know anything about python or programming..

I'm just a engine tester who likes your automatic tools
I will not disturb you with sending files to convert them..you do already enough for people who are interested in your tools!

Kind regards,
JP.

I even agree that it is probable. But I do not agree that it is a certainty and even as framed above it is clearly a hypothesis.
