Carl Kockelkorn (26-11-1843 - 16-07-1914) German composer
Carl Kockelkorn and Johannes Kohtz published their first common chess problem when they were 17 and being in total accord after a short while they decided to publish their problems as co-productions. After Carl Kockelkorn died in 1914,
Kohtz still published his problems under both authors names.
Together they founded the logical school of chess composition, in reaction against the old German school founded by Johann Berger.

Show SolutionThe main plan fails to Black's O-O# forward defense.
Main plan: -1.Kf6-f5? Se7-g8 -2.Kg7-f6 and 1.Bd7#, but this fails on the forward defense -1...Se7-g8 and 1...O-O!#
Solution:
-1.g2xBh3 g4-g3 -2.Ra2xBc2!
[
Now Black can't uncapture anything, because the pawn structure and promoted Bishop need 5 captures.]
-2...Bd1-c2 -3.Bc3xRa5! Ra4-a5 -4.Ke4-f5 Ra5-a4 -5.Kd5-e4 Ra4-a5 -6.Kc4-d5 Ra5-a4 -7.Kb5-c4 Ra4-a5 -8.Kb4-b5 Ra5-a4 -9.Rd2xSa2 Sc1-a2
[
Because of this move, the white Bishop had to come from c3 on the 3rd move]
-10.Kb5-b4 Ra4-a5 -11.Kc4-b5 Ra5-a4 -12.c2xQb3 Qb2-b3 -13.Kd5-c4 Ra4-a5 -14.Ke4-d5 Ra5-a4 -15.Kf5-e4 Ra4-a5 -16.Kf6-f5
[
and because of the forward defense Qb2xc3#, the white Rook had to go to d2 on the 9th move. Because there are 16 black pieces on the board, the white e-pawn had to promote on e8, so no forward defense O-O now!]
-16...Se7-g8 -17.Kg7-f6 & 1.Bd7#
