Babson-Task

The Babson Task is a task of the chess composition. It calls for a mutual Allumwandlung in immediately successive trains in each case by the same farmer.

Formation of the task

The term goes back to the American Joseph Babson ( born December 26, 1852 † December 20, 1929 ) back. He published in 1914 the first mutual Allumwandlung, which was, however, still performed by three farmers. Babson made ​​it in the following years, not to accomplish this task. Therefore, the Americans Powers launched in 1925 under the name Babson tournament a composition tournament and donated as a prize $ 20 (or 25, if the key move is a sub- transformation ). The tournament won Henry Wald Bettmann, but later submitted pieces by H. Krämer and W. August were almost identical.

Solution:

1.a8L!

After the key move (also a sub- transformation ) is the emerging black figure to eliminate. In the conversion into a lady that is except for the above-mentioned variants always possible in the conversions in rook and bishop prevents White checkmates his hand, and in the conversion to a knight, the field is d7 defended, could escape through the black otherwise.

After the presentation of the Babson task in self- Matt its realization still seemed impossible in an orthodox task. Especially the Paris metallurgy engineer Pierre Drumare ( born October 26, 1913 † April 2001) explored in more than 20 years systematically Babson, but without finding a correct representation. Only until then completely unknown composer Leonid Vladimirovich Jarosch 1983 could present a correct task without conversion figures in the starting position. The problem with the number 23 was headlined "! Jest task Babsona? " ( German for "Is the Babson task ?") and was later known as the problem of the century world.

Solution:

1.Txh4

The Cooperative State were accepted in the Erstdarstellung so. A few months later Jarosch created a dual free version, which was awarded 1st prize. In orthodox problem the sub transformations in rook and bishop are motivated by stalemate avoidance.

Meanwhile, 16 Orthodox problems with the Babson task were composed, and also with fairy tale characters and then each 5 sub- transformations of the Babson task was realized. Pierre Drumare also has created a correct Babson. Nevertheless, continue to be a challenge remained. So far, only the same transformations successively set up, and in 2003 Peter Hoffmann went back to work on cyclic Babson. In September 2005, published in the German magazine chess under the number 15.778 subsequent problem.

Solution:

1.Lxc6

Erstdarstellung the cyclic Babson without conversion figures. A later version of this study received a trophy.

The Babson Task in the study

The Babson Task was not fully met in a study, however, he was presented with three ( instead of four ) transformations. A project implemented in 2005, composing thematic tournament by Gerd Wilhelm Hörning, Gerhard Josten and Siegfried Hornecker for Babson task in the study with a prize fund of € 500 remained without sent.

January Rusinek

January Rusinek ( born December 2, 1950 in Cracow) has tried to portray such a " three-quarter Babson ", but failed. Presumably its creation Gady Costeff inspired.

Proposed solution: 1.Tb8 -b1 e2- E1D Tb1xe1 2 , and now:

There are many dual exists, moreover the task after 1 ... G1d 2.fxg8D Dd1 is unsolvable.

Gady Costeff

Gady Costeff ( born May 7, 1961 in Beersheba in Israel) has shown the three-quarter Babson correctly.

Solution: 1.d6 - d7 Tc8xe8 2.Tb2xb1 , and now

First correct representation of a three-quarter Babson.

Solution: 1 ... LG8 - c4 ! 2.Kd3 -d4 - d7 Tc7 3.Kd4 - c5 -a4 Sb6 4.Kc5xc4 Sg 2 -e3 5.Kc4 - b4 Td7xb7 6.Kb4xa4 Se3 -d1 7.Ta1xd1, and now:

Beautiful presentation of the subject, especially through the long introduction.
