Problem-715
Tichomir Hernadi
1st Prize, StrateGems 2012 h#n

8/kb1r4/2Bp4/6p1/q7/2p3bp/2r4p/4s2K (2 + 12)
h#7,5

1...Be4 2.d5 Bxc2 3.Bb8 Bxa4 4.c2 Bc6 5.c1=B Bxb7 6.Be3 Bc8 7.Ka8 Bxd7 8.Bea7 Bc6#

The wBc6 makes two roundtrips (in German : RundLauf) like the figure 8!
 

Problem-716
Kostas Prentos
2nd Prize, StrateGems 2012 h#n

8/1p5r/6q1/3p4/4r1k1/1p6/1p2S3/1K3B2 (3 + 8)
h#4,5  2 solutions

1…Sd4 2.Rh2 Bb5 3.Kh3 Se6 4.Qg3 Bd7 5.Rh4 Sf4#
1...Bh3+ 2.Kh5 Bf5 3.Rh4 Bc2 4.Qg5 Bd1 5.Rh6 Sf4#

The White forms twice a battery Knight / Bishop and the wS goes to the same square to give a model mate. There is a mirror-Echo of the mates in the two solutions. We see the self-blocks of the Black and a Pelle-move of the pinned wB. The position of the wK defines the sequence of the black moves.
 

Problem-717
Christer Jonsson, Rolf Wiehagen
3rd Prize, StrateGems 2012 h#n

8/3pK1p1/3p3p/3p1Sp1/3p1pBs/5P2/8/7k (4 + 10)
h#3,5  duplex

White plays : 1...Sxh4 2.Kh2 Sg2 3.Kg3 Se3 4.Kh4 Sf5#

Black plays : 1...Sxf5+ 2.Kf7 Se3 3.Kg6 Sg2 4.Kf5 Sh4#

Reciprocal captures. When the piece, which gives mate in another solution, is captured we have Theme Zilahi. We see model mates. The interesting part is that the knights step on the same squares, making their roundtrips, but in opposite directions!

Composers' cooperations (3)

In this post we will see five problems created by cooperative composers. In general, the chess composition is a lonely activity. Most of the time it is you and your chessboard, or even your computer running the proper software. But often the composers share an idea with someone else and the composition has more than one parents.
Who has done most of the work? Finally, it does not matter. The cooperation is worthwhile.
Whose name will be written at the top? We said, it does not matter. The main thing here is that the composers cooperate and sometimes they become friends.
There are in the chess history rare cases, where composers having together awarded compositions, at the end they do not speak to each other.
