Sting SF 21

Post by lech » Sat May 09, 2020 12:43 pm

My project sting is dedicated to solve difficult studies, and not middle-game tactical positions.

There are a few important modifications.
Also I added an old code ("lazy King") tried by me earlier.

The "IQ" test is a very important part of my project (Sting) and doesn't contain middle-game tactical positions and technical endgames.
Here are positions dedicated to all engines to test so-called by me "quasi-intelligent" their abilities.

Don't use such external tricks like: rule-50 changing, null-move disabling, special parameters and others.
The external tools like: MultiPV, tablebases, "backward-forward" and "Monte Carlo" are not welcome too.

"WIN" means the correct solution and some non-zero score.
Don't do the test in a machine way. Test and analyze each of items separately!

I learned about your first position from Bernhard Bauer here:

http://www.talkchess.com/forum3/viewtop ... 10#p753058

I don't know if he created the position. I did not find any earlier appearance of this position, but I didn't search carefully.

If it is so important and I remember good, I am the autor of items: 2, 4, 40, 41, 100 only and I am still alive. :)

YACPDB lists Mendheim's problem in its number 311979:

https://www.yacpdb.org/#311979
YACPDB wrote:Mendheim, Julius
The New York Clipper, 25 May 1867 (E579)
1.Be5+! Rc7 2.Be6 ~ 3.Bd7 ~ 4.Kf7 ~
5.Ke8 ~ 6.Kd8 ~ 7.B×c7#
5.Ke7 ~ 6.Kd8 ~ 7.B×c7#
It is true that the problem appeared in The New York Clipper of 25th May, 1867 (page 58, Enigma No. 579, hence 'E579' from YACPDB):

The New York Clipper, 25 May 1867

BY MENDHEIM.

K at his Kt 6, B Q4, B Q Kt 3, P Q R 6th.
k at Q Kt sq, r Q R sq, r Q B sq, p Q R 2, p Q Kt 3, p K Kt 2, p R R 3d.

White to play and give mate in seven moves.
But I read somewhere at TalkChess that this problem is dated from 1832. I found that source: Aufgaben für Schachspieler nebst auflösungen ('Tasks for chess players with resolutions'), 61st task:

Aufgaben für Schachspieler nebst auflösungen (1832)

Book preview
Aufgaben für Schachspieler nebst auflösungen (1832) wrote: Stellung der Steine.
Weiß. K-g6. L-b3, d4. b-a6.
Schwartz. K-b8. T-a8, c8. b-a7, b6, g7, h6.
Der Weiße macht in 7 Zügen matt.
Problem without diagram at page 14 and solution at page 44.

Other curious fact is the presence of descriptive notation in 1867 while there is a kind of algebraic notation in 1832 (same in 1814, please see the off-topic problem source below).

------------------------

Just a bit off-topic, I found a fun problem from the same author in his book Taschenbuch für Schachfreunde ('Paperback for chess fans') of 1814.

Taschenbuch für Schachfreunde (1814)

Book preview

Problem 27 (pages 53 and 54). Condition: checkmate in a2 square in 12 moves only moving the white knights.



What a knights tour!

It is not the shortest checkmate but I consider the knights checks theme entertaining.

------------------------

I hope no typos.

Regards from Spain.

Thanks for the research about the author. If theme wasn't moving knights only, White could mate with 6.Qg3# instead of Ng6+ already, but yes, it's really beautiful for the eye of the human player.

Indeed it seems to be much better to save the first item of the "IQ" test in an original way as study. Thanks!
